Prevent iOS from taking screen capture of app before going into background

Question

You all might know that iOS takes a screen shot of your application before throwing it into the background. This is usually for a better User experience like quick animation

Answer 1

I came across the same issue, and my research has lead me to the following answers:

• set a blurry screen overlay before the app goes in the background and once the app becomes active remove this overlay

• if it is iOS 7 or later you can use the function ignoreSnapshotOnNextApplicationLaunch

See in apple documentation: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplication_Class/Reference/Reference.html#//apple_ref/occ/instm/UIApplication/ignoreSnapshotOnNextApplicationLaunch

I hope this helps somebody.
