如何防止ios11中的屏幕记录

Question

由于某些原因，我们的APP不希望人们记录屏幕，但在ios11中一个新功能可以让用户在那里录制iphone屏幕，所以是否有一个API或通知指示我用户正在录制现在非常感谢你

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
}];
