How To Pin An App To Screen For Easier Multitasking On iOS 9 iPhone
With PullOver tweak you can easily pin an app to screen for easier multitasking in iOS 9 that can be useful depending on what you’re doing on your jailbroken device. For example, you could be watching videos on Youtube or browsing the internet on Safari and you can quickly click on the pullover button to bring your frequently used application to the front. Use it and then return to whatever you were doing before.
To get PullOver tweak on your device head to Cydia’s BigBoss repository and download it for free. The tweak has been tested to work on iOS 9.0.2 up to iOS 9.3.3. To start to configure PullOver, you’ll need to navigate the tweak's preferences pane in the Settings app after installation:
From Settings you can configure the appearance of the PullOver button, turn the tweak on or off and more importantly choose an Activator gesture that will be used to pin an application.
When you invoke the tweak, you’ll see a small slider at the edge of your iPhone's screen; invoking the action again hides the slider from view.
While the slider is on your screen, you can pull on it to bring up a windowed interface of your selected app. In this windowed mode, it is possible to use the app like you normally would.
You can play with the size of the PullOver button and change background or arrow color, all of which can help you achieve the look you’re want.
