How to use Split View (split screen) on iOS 9
iOS 9 supports split screen feature to use two apps at the same time (Split View). However, this feature is only available for iPad Air 2 , iPad mini 4 , iPad Pro and only with certain supported apps. The steps are as follows:
Step 1 : From the main screen select an application, here QTV selects the web browser Safari .
Step 2 : Drag from the right edge of the screen to a column containing Split View supported applications .
Step 3 : Select one of those applications, here QTV select Map . Notice a small white line in the middle of the left edge of the app.
Step 4: Drag the small bar to the left, the screen will split in half so that two apps can run at the same time.
Good luck.
