how to prevent screen record in ios11

问题:

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

回答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.

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
}];
