How to be productive in iOS 9
Split View, Slide Over, Picture in Picture
With iOS9, Apple has introduced a new feature called Multitasking that takes the iPad to the next level. By running two apps side by side, you can be more productive than ever before. While this feature is only fully compatible with the iPad Air 2, iPad mini 4 and iPad Pro (and in limited ways on some older iPads), it's an incredibly powerful feature that might be worth the upgrade. (Note that Multitaskingg does not work on any model of iPhone)
Multitasking comes in three forms:
Split View: You can have two apps running fully side by side in Split View mode
Slide Over: You can peek at an app and use it in limited ways with Slide Over
Picture in Picture: You can run a video in a window all its own in a mode called Picture in Picture.
This handy feature lets you run a second app on your iPad without leaving the app you're currently using. To use Slide Over:
1. Open Safari, Mail, Messages or any other app that supports Multitasking. This includes most apps bundled with iOS, as well as apps downloaded from the iTunes App Store, including Microsoft Office (Word, Excel, PowerPoint), 1Password.
2. Slide your finger from the right edge of the screen towards the centre. This will "pause" the main app you have open and initiate Slide Over view, allowing you to select from a column of supported apps. Tap one to start using it.
3. While you are in this mode, you can switch apps by swiping from the top of the screen on the Slide Over window (just like you were opening Notification Center). If you want to exit Slide Over mode, either press the Home button or tap the drag bar and pull it back to the right side of the screen and let go.
After initiating Slide Over, if the two apps you're using support multitasking, then you'll see a drag handle on the Slide Over window. Dragging this handle to the left will let you enter Split View mode for true side-by-side multitasking. From Slide Over mode, drag the handle to the centre to switch to Split View mode.
When using apps in Split View mode, iOS 9 will remember the sizes of the windows that you're using, so if, for example, you use the Home button to exit to the Home screen, then open another app, then return to one of the two apps that were split in multitasking mode, the windows will open at the sizes they were previously. As with Slide Over, if you want to exit out of Split View mode, simply grab the drag handle and slide it off to the right side of the screen until the secondary app disappears from view.
Picture in Picture
Picture in Picture (commonly called PIP) refers to the feature in iOS 9 that lets you overlay a small video window on top of all other apps and the Home screen, allowing you to keep the video playing while navigating iOS and going in and out of apps.
Activating PIP can usually be accomplished in one of two ways. The first is to simply play the video in a compatible app, then press the Home button - if the developers have set the app up to do so, then the video will minimize to a PIP window on the Home screen.
The second way is by manually activating PIP from the video player window. This is how it's done within Safari and other apps that use the standard player controls available in iOS. If you encounter a player with a PIP button, you can tap this button to shrink the player down into one of the four corners of the screen, allowing you to keep navigating inside of the app or leave the app by pressing the Home button, all while the video remains playable.
You can resize this mini player by using a pinch gesture, play or pause the video by tapping it once then tapping the play/pause button, stop the video by tapping the "X" button, or restore the app the video belongs to (and exit PIP mode) by tapping the maximise button. Minimising the Picture in Picture window is easy: just push it toward the edge of the screen.
In addition, the PIP window can be moved to any of the four corners of the screen by simply dragging and releasing it. You can also make the PIP window minimize itself further by pushing it further towards the edge of the screen. The audio continues to play, but only a small portion of the video will remain on the screen.
