More than anything else, iOS 9 should be appreciated by iPad users, and for good reason. It's all about the new multitasking features. The key one is Split View, which will only be available to owners of the brand new iPad Pro, iPad Air 2 and its "little brother" iPad mini 4. It allows you to display two applications on the screen at the same time, doubling (or even more) increasing productivity. Read below for how it works.
To switch to Split View, you swipe in from the right edge of the screen and bring up Slide Over, another new feature that lets you view and interact with your running apps in a small widget. To switch the application from Slide Over to Split View, you just need to drag the border of the window and expand it to half the screen.
Both applications will be pinned to the screen, and you can work with them at the same time, as if it were a single application. You don't need to bring up the multitasking menu to switch between programs, they don't reload - you get a completely seamless user experience.
Work
Anyone who has used an iPad for work knows what a painful experience it is. Usually doing any serious task on the tablet turned into endless switching between Safari tabs, which reload when not needed, and between applications through the multitasking menu. It is difficult to endure such torment for a long time, it is easier to get a laptop or go to a computer.
With Split View, you can jot down some drafts in Safari while lying in bed while viewing work notes in Notes or press releases in Mail. As promised by Apple, the experience in this case is completely seamless, the feeling of stiffness that was previously impossible to get rid of when working on the iPad is gone.
As strange as it may sound, this approach increases productivity. On the computer, each of us has a lot of open windows, some even have several monitors - and our attention is needed everywhere. On the iPad, everything is much easier. All you see is the applications you are working with and need at the moment.
Entertainment
Of course, Split View will be useful not only for work tasks. While watching your favorite movie, you can immediately open Safari and find out the name of an actor or the name of that catchy song. You can use it to find a restaurant or movie tickets while chatting with friends via FaceTime, or use Maps to get directions sent in Mail.
Let's say you want to edit holiday photos to create an album. With Split View, you can simultaneously open the editor and Safari with instructions or the player with a video tutorial.
Application management
Using Split View, you can quickly switch between programs with a swipe gesture from the edge of the screen or resize them by dragging outside the window border.
In landscape mode, you can give applications half the screen, or give 3/4 of the space to one and a quarter to the other. Surprisingly, Split View also works in vertical orientation, although without the ability to choose the proportions of space for applications.
If there is a need to switch one of the applications to full screen mode, then this is easy to do with a stretch gesture in the desired direction.
It is very convenient that Split View remembers the location of windows when switching applications. Let's say you're working in Safari, open next to Notes, then switch to Messages to reply to someone you're talking to. When you return to Safari, its window, like the Notes window, will be in the same place.
Restrictions
At the moment, Split View is not ideal. The feature has a limitation and only works with built-in iOS apps. However, Apple has opened the corresponding APIs that will allow third-party developers to add Split View support to their applications.
Many people are already working on it, so we will probably see more applications that support Split View in the near future. The future of iPad productivity will only get better and better as these apps expand.
You can easily open YouTube next to Twitter, Evernote next to Chrome, or Pages along with your banking app. These combinations make the iPad a useful work tool that can truly replace your laptop forever.
Rejection of the PC
Even at the launch of the first iPad, Apple envisioned it as a post-PC device, an ultra-portable gadget that can do everything from surfing the Internet to editing videos and writing novels. All these opportunities were hampered by the lack of true multitasking. The turning point in this should be iOS 9.
With the announcement of the iPad Pro and its imminent release, it all makes more and more sense. With the proprietary Smart Keyboard, iPad becomes almost like a laptop. And this is just the beginning!
Apple unveiled a new generation of the iOS 9 mobile platform at its WWDC developer conference in San Francisco. In this version of the system, the Siri voice assistant received a new interface and, according to Apple, is now 40% faster. Siri has learned to predict the user's desires and, for example, will automatically launch the player when the owner of the smartphone goes for a run in the morning, or analyze incoming mail and find potentially probable calendar appointments there. In addition, Siri has learned how to search for various content in app stores, and search results now include data from third-party applications and can take into account the user's location. So, Siri will understand requests like "Show me the photos taken last August" or "Remind me to pick up coffee from the roof of my car."
Apple also said that it is opening up a toolkit for third-party developers, and now they can fully connect to search in iOS. The company promises complete confidentiality of data - they are not associated with the owner's Apple ID or any Apple service, and are not transferred to third parties.
Another innovation in iOS 9 is the new personalized Proactive Assistant service. It processes information from many different sources, including Siri, Contacts, Calendar, Passbook, Maps, and third-party apps, to offer the user the information they need. Proactive is intended to replace the Spotlight search function, and can be accessed by swiping the start screen to the right. The service will provide iPhone and iPad owners with the necessary and useful information based on their habits and personal preferences. For example, if a user checks email or Facebook at 9 am, the assistant will automatically show icons of the corresponding programs at that time. If a person calls a colleague at work every Thursday at 17:00, then on the Proactive page by that time the hint “Call a colleague” will appear. At lunchtime, it will show which cafes or restaurants are located near the place where the person is.
Pre-installed applications have been updated, including Notes and Maps, as well as a new News application. Notes received support for text formatting, creating lists, adding photos and handwriting. Public transport routes have been launched in the Maps app. iOS 9 uses multiple modes of transport when calculating a route, if this will reduce travel time. In addition, Apple Maps will show where cafes, shops and ATMs are located in malls, as well as gates at airports. So far, the recommendations will be valid only for ten cities, including Berlin, Chicago, London, New York, Philadelphia, San Francisco, Washington, etc.
As for News, it will collect articles from various sources. The operation of the application is similar to popular news aggregators, when the user can select topics and publications of interest to him and receive content in a specially adapted layout that will be convenient for reading and viewing pictures. The articles will include photos, image galleries, videos and animations. Users can "like" certain materials and add interesting content to bookmarks. It is important to note that searching and adding content is possible not only in general categories or publications, but also in more personalized searches. For example, you can find all the articles about the Swift programming language, subscribe to them and receive information about this topic from various publications in the future. Apple announced News for the US, Australia, and the UK only.
Among the features of the updated Mail application is email scanning. This is necessary to identify contacts when calling from unknown numbers, iOS 9 will try to find such numbers in the mail signature. The Apple Pay service, as previously reported, has become international - in July, the UK will also be connected to "apple" payments. In addition, the Pay features have been expanded - the service now supports bonus cards. Apple Pay has secured the support of new banks and partners. The company announced that next month the service will launch in England, where it will be possible to use it not only to pay for purchases in stores, but also on buses and the subway. The conference also featured an updated version of the payment app for iOS 9, which will support a variety of loyalty programs. In addition, the current Passbook app will be renamed Wallet.
A lot of emphasis has been placed on improvements to the iPad, with the most important being easier task switching and split screen for different apps. The screen is split into two parts in a ratio of 50 to 50 or 70 to 30. To quickly select another program from the multitasking side menu, just double-tap the Home button. Multi-window mode will make it easier to interact with multiple tasks. For example, the user will be able to keep two Safari tabs or a Pages document in front of his eyes, transfer content (text, video, photos) between programs, etc. Both applications work simultaneously.
Tablets will also be able to work in picture-in-picture mode. For example, if a user, while watching a video, wants to check their mail or write a letter, then when they open the email client, the video will continue to play in a small window in the upper right corner of the screen. The new option works on iPad Air, Air 2, mini 2 and mini 3, however full multitasking functionality is only available on iPad Air 2 due to 2GB of RAM. Developers will be given the tools to create applications that support the new multitasking mode.
Apple engineers did not forget about the iOS keyboard, on which the labels "Paste", "Cut", "Copy" and others appeared. If you place two fingers on the keyboard, it turns into a touchpad, which is especially useful for moving the cursor.
In iOS 9, a low power mode will appear, which will help the iPhone stretch an additional three hours. Another important announcement for owners of devices with 16 GB of internal memory - the updated operating system will "weigh" 1.8 GB instead of the current 4.6 GB.
It was also announced the release of the Swift 2 programming language, which Apple decided to make an open source project. It will be possible to use the new features of Swift 2 towards the end of the year.
The new iOS 9 can be installed on iPhone 6, iPhone 6 Plus, iPhone 5s, iPhone 5c, iPhone 5, iPhone 4s, iPad 2, iPad 3, iPad 4, iPad mini and iPod touch 5G. You can download iOS 9 beta 1 now. The final version of iOS 9 will be available for download in the fall.
Since the popularization of smartphones, users have faced the problem of low autonomy of mobile devices. Large touch displays, powerful processors, power-hungry apps all contribute to battery drain to varying degrees. "Experts" advise to manually close these same applications to improve performance and increase battery life. In fact, this is one of the myths that has existed since the first versions of iOS.
Many iPhone users tend to unload previously launched applications from memory. Of course, multitasking works fine, but why take up extra megabytes of RAM? Moreover, there are rumors that several simultaneously running programs adversely affect charging. In fact, this has the exact opposite effect on the system. The paradox is that unloading applications from memory only contributes to the accelerated discharge of the battery.
Myths and reality
To begin with, it is worth understanding that the implementation of multitasking in iOS is at a very high level. No matter what the haters say, the “OS” works great even after running a couple of dozen applications. Sounds like praise, but Apple programmers eat their bread for a reason. All developers are subject to the same requirements for creating software.
It's a common myth that forcing apps to close will save battery. By not allowing the system to manage all the processes on its own, you are making a mistake. The fact is that the very action of calling the multitasking mode and unloading programs from memory consumes much more energy than their “working in the background”.
Perhaps most will not believe and think that it is a mistake to use the terms "background applications" and "energy efficiency" in the same sentence. We assure you that reservations and other errors in terminology are excluded. Multitasking is launched by double-clicking on the Home button. And the complete closure of programs is carried out by swiping the window up (valid for iOS 9).
The reality is that as soon as you exit the application, once "tapping" on the "Home" key, its work stops: the application stops accessing the processor, and the memory that it occupied is freed up over time. Of course, there are exceptions when the system does not stop the program from running in the background. For example, sending an email, playing music, or automatically downloading updates. Nevertheless, even such "wastefulness" on the part of the "OS" is economical in relation to the battery of the device.
When you manually close an application, the operating system must unload the task from memory, which consumes battery power. When you reload the same application, the system again needs to load it into RAM, which will also result in energy costs. Thus, forcibly closing applications, you consume battery power twice. Being in the RAM of the device, it does not affect its autonomy in any way.
How multitasking works in iOS
In total, applications in iOS have five types of states:
- Out of Service - The application has been terminated or has not been started.
- Inactive - the application is active but does not receive events (for example, the user has locked the screen).
- Active - the normal state of the application in use mode.
- Background - the application is hidden, but it is executing code.
- Suspended - the application is in memory but is not executing code.
Active and inactive for this topic are uninteresting. Most people get confused when an app goes from being active to being in the background, to being suspended, and then to being inactive.
When you press the Home button, the program switches from active to background. Most apps go into pause after a few seconds. The first technical nuance is that the suspended application remains in the device's memory. This is so that it can continue working faster if you decide to return to it. However, it does not use processor resources and battery.
It can be assumed that if the software is in memory, then it must be removed from there to free up resources. In reality, iOS does this on its own. If you have a paused application and you run resource-intensive software, such as a complex 3D game, iOS unloads the suspended program from memory and moves it to the Idle state. In other words, it will be completely removed from RAM and started from scratch the next time it is started.
conclusions
The main rule of iOS multitasking is as follows: the multitasking bar is just a list of recently used apps, no matter what state they are in. The operating system unloads tasks on its own - when necessary.
In what cases should you close applications and free up device RAM? The answer is simple - in theory never. It is extremely rare that situations occur that should force you to restart the program. Unless it hangs or does not work correctly. It's probably hard to believe, but iOS itself does a great job of distributing the load on the processor and battery. Apple products are a technique that you just need to use without creating unnecessary difficulties for yourself.
On June 5, at the opening of the WWDC 17 developer conference, Apple announced a new version of the iOS 11 operating system. After ten beta versions for registered developers and public testing, new firmware for iPhone, iPad and iPod touch players became available. From September 19, the iOS 11 operating system can be installed on 22 Apple mobile devices.
Since the first beta version of iOS 11, the iguides editors have been telling you about all the changes and improvements in the new version of the operating system, and for the release of the update, we have prepared a complete list of the most important and interesting innovations that you should definitely know about.
Despite the relatively small list of changes that appeared only for the iPad, the iOS 11 operating system is a very important step for the further development of Apple tablets and the possibility of using them as work and professional tools. New principles for switching between applications, improved multitasking, multiple selection and drag and drop of files between applications - all this will significantly change the familiar user experience of iPad owners.
1. New Dock 
The bottom line now has more icons and app signatures are gone. A block with three recently launched applications has also appeared, separated from the rest of the icons, and the third can change to the program with which you are working on another device. With a stroke from the bottom up, the Dock can be launched on any screen to quickly switch between applications.
2. Multitasking 
Now an additional application can be opened on the screen from the Dock - in Split View mode, it will appear along with the current one on the same screen, and in Slide Over mode, the second application can be moved to the left. In total, up to four apps can be open on the iPad screen at the same time: two in split-screen mode, one on the side, and a video player window.
3. Drag and drop and multiple selection 
Now you can transfer text, photos and files from one application to another. iOS 11 lets you drag and drop documents one at a time or select multiple documents at once. By the time the new operating system was released, apps with drag and drop support began to appear in the App Store.
4 Apple Pencil 
With Apple Pencil, you can now take instant notes on PDF files and screenshots, jot down a note right on the lock screen (it will be saved in the Notes app), and draw and write in Notes, Mail, and other apps. In some cases, automatic adaptation of texts and drawings occurs - for example, in Notes, printed text will automatically step aside, making room for sketches.
5. Scanning and signing documents 
The new document scanning feature in Notes automatically detects the document, crops excess around the edges, and straightens the image. This allows you to digitize papers, fill out and sign them with your Apple Pencil, and then easily save files or send them to others.
6. Quick Type Keyboard 
Letters, numbers, symbols and punctuation are now on the same buttons, which reduces the number of layout switches. To select the desired character instead of a letter, simply swipe down on the key.
You can learn about other changes in iOS 11 that apply to all mobile devices at once in other parts of the review. For example, we talked about new system settings, scanning QR codes with the camera, changes in the Messages app, editing the Control Center, and other important and useful innovations in the iOS 11 operating system.
On iPhone and iPad, you can run multiple apps at the same time. Thanks to multitasking, you can combine the functionality of several applications, for example, enable recording in Voice Recorder and open a toy. Audio recording in the background will be accompanied by a red bar at the top of the screen (only visible on the home screen). And this is just one example that raises several questions about how multitasking works in iOS. Let's try to figure it out...
How to force close an app on iPhone, iPad
But first, a simple answer to a simple question. If the program freezes, closes automatically, or refuses to start normally, try closing it forcibly and then restarting it.In order to view or close running games and programs in iOS, you must double-click the "" button. This will take you to the multitasking panel, where you can view all previously opened applications. Closing is done by moving up the selected window.
In principle, the multitasking interface in iOS is intuitive and its functionality is obvious. Swipe left-right scroll through the applications, and access them by touch.
It is impossible to close all applications at once, but you can close three at a time by swiping them up with three fingers.
How multitasking works in iOS
When you exit an application, it cannot be said that it is minimized, as it happens in Windows. By and large, applications in the multitasking panel do not work and practically do not consume the resources of your iPhone, iPad. Why it happens? Let's take a look at the technical side...One of the developers of iOS, in one of his materials, technically describes the five states that an application can be in;
- active state - the application is currently open and in use;
- inactive state - at the moment the application is open, but not used (for example, the device screen is locked);
- background activity state - the application is closed, but continues to be active in the background;
- suspended state - the application is closed, does not show activity;
- non-working state - the application was forcibly closed or did not open at all.
- The application is launched and it works in full, consuming the resources of your gadget;
- after pressing the "Home" button, the application closes, but continues to be active in the background for up to 30 seconds;
- if after this time the application did not require iOS to be able to work in the background (for example, to download a large document or complete some operation), it will automatically go into a suspended state, in which it will no longer consume device resources, but will continue to take up space in RAM;
- the application goes into a non-working state if you run another game or program that needs more RAM.
Not all applications are allowed to work in the background for a long time, after 10 minutes the game or program will be forcibly transferred to a suspended state, with the exception of those programs that are designed to work in the background - music programs; apps that track your location; programs that work with external accessories and so on...
"Then how do you get notifications for those apps that are in the unloaded or suspended state?" - you ask. To work in the background, developers of games and programs use specially provided APIs in Apple. I will briefly describe them as far as my knowledge allows.
- Background Fetch - The API works with applications on a polling basis that adapts to the user. A sort of intelligent system for assessing background activity. For example, the user launches the program once a day, the mechanism adapts and checks for updates quite rarely, thereby practically “waking up” the application. If the user opens the program dozens of times a day, the API will access it more often. The mechanism also adapts to the time at which the user uses the application, updating the content before opening it.
In addition, the content update adapts to periods of low power consumption of your device, for example, in the area of \u200b\u200bWi-Fi or when connected to a charger.
- Remote Notification are the most common push notifications. An update of a content or something else is registered on the developer's server, after which a corresponding push notification is sent to the user. This technology also practically does not increase the cost of system resources by the application, since it works only at the moment when a notification arrives.
Do I need to close apps on iPhone, iPad manually?
A difficult question that can be answered with both yes and no. In most cases, the multitasking bar does not display a list of running applications, but rather a list of recently used applications.On the one hand, it makes no sense to upload manually, since iOS does everything for you when necessary. And applications that are in a suspended state will not use up battery power. But on the other hand, many applications can quietly work in the background for another 10 minutes, and some even devour your battery power all the time. By closing them, you will reduce battery consumption. Most often, applications that are allowed to run in the background all the time are very well optimized and should not create problems for you, except for those that use the GPS / Glonass module.
If you really notice that after force closing games and programs, your iPhone, iPad works better or the battery is used up more slowly, then you are using some kind of application that is very active in the background. If you don’t notice the difference, then there’s no point in closing applications manually, as I said above, iOS will do everything for you.
