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
}];
