how to prevent screen record in ios11

Question

To some reasons, our APP dont't want people record screen, but in ios11 a new feature can let user record there iphone screen, so is there an API or notification indicate me user is recording now thank u very much

Answer 1

You can detect if the screen is being recorded with:

UIScreen.main.isCaptured
// True if this screen is being captured (e.g. recorded, AirPlayed, mirrored, etc.)

You can't prevent it using project settings, but you could use a modal or something to request the user to disable it. Not sure how that might workout with your AppStore submission.

Answer 2

You can use kvo observe UIScreenCapturedDidChangeNotification in iOS 11 like this

NSOperationQueue *mainQueue = [NSOperationQueue mainQueue];
    [[NSNotificationCenter defaultCenter] addObserverForName:UIScreenCapturedDidChangeNotification object:nil queue:mainQueue usingBlock:^(NSNotification * _Nonnull note) { 
 //code you want execute
}];
