How to disable screen Recording in iOS app

问题:

Is there any way to disable the screen recording? or is is possible through a configuration profile? or any third party library is available?

回答1:

NotificationCenter.default.addObserver(self, selector: #selector(preventScreenRecording), name: NSNotification.Name.UIScreenCapturedDidChange, object: nil)

And create a view inside main view and prevent like that.

(void) preventScreenRecording {
if (@available(iOS 11.0, *)) {
    BOOL isCaptured = [[UIScreen mainScreen] isCaptured];

    if (isCaptured) {
        self.blockView.hidden = false;
    }
    else {
        self.blockView.hidden = true;
    }
}

回答2:

When your app is started you can test UIScreen.isCaptured property and show some splash screen if it's set to true.

You should also observe (subscribe in some place for) capturedDidChangeNotification notification, and do same thing (show splash screen) if UIScreen.isCaptured is set to true.

sharedRecorder.stopRecording( handler: { previewViewController, error in    
    if let error = error {
        print("\(error.localizedDescription)")
    }
    if UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiom.pad {
        previewViewController?.modalPresentationStyle = UIModalPresentationStyle.popover
        previewViewController?.popoverPresentationController?.sourceRect = CGRect.zero
        previewViewController?.popoverPresentationController?.sourceView = self.view
    }
    if previewViewController != nil {
        self.previewViewController = previewViewController
        previewViewController?.previewControllerDelegate = self
    }
    self.present(previewViewController!, animated: true, completion: nil)
    })
    return
}
