How to catch a click in any area of ​​UIWindow?

Question

Objective-C

The essence of the problem: It is necessary to record a video from the screen of a mobile phone so that it can be seen where the user clicks.
Question: Is it possible to catch the touchDown / touchUp events anywhere, even on top of other controls, but so that these controls also receive this event.
Or maybe there are already other solutions to this problem?
Thank you.

Found this solution:

UIGestureRecognizer* tapper = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                              action:@selector(handleSingleTap:)];
tapper.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapper];

- (void)handleSingleTap:(UITapGestureRecognizer *) sender {
    NSLog(@"handleSingleTap");
}

True, tap on the UIView background is not caught, but you can probably put some kind of control on the bottom layer and catch tap on it too ...

Have a look at ready-made components on cocoacontrols, it doesn't always make sense to reinvent your own wheel.
