You can't completely prevent this. Even if Apple allowed disabling recording, jailbroken phones could probably get around it, and at the end of the day, recording the screen with a camera is always possible. – Carcigenicate Jul 30 '17 at 16:27

I do not consider jailbreak now, do you know ios11 have such an API? – Wong Sam Jul 30 '17 at 16:30

No. It's been a long time since I've dealt with Apple. – Carcigenicate Jul 30 '17 at 16:31

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.

This is not only screen capture but also mirroring with airplay. So not the exact solution. – birdcage Sep 14 '17 at 12:03

It's worth noting that I have seen this value return an incorrect result multiple times in testing. Frequently, we encounter a bug where the we *are* using screen recording but isCaptured returns false. – FateNuller Sep 29 '17 at 15:05

@WongSam if this is the correct answer that solves your problem, don't forget to accept it (green tick is) ;) – Ahmad F Apr 26 '18 at 06:47

if UIScreen.main.isCaptured is true, then How to Stop that record? I have start screen record, by pressing RECORD button from CONTROL CENTER, then immediately, if I open my app, then I have to STOP that record programmatically. – McDonal_11 Apr 09 '19 at 17:36

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
}];
