UITapGestureRecognizer tap on self.view but ignore subviews

ios, uitapgesturerecognizer

Solution

You should adopt the `UIGestureRecognizerDelegate` protocol inside the `self` object and call the below method for checking the view. Inside this method, check your view against `touch.view` and return the appropriate bool (Yes/No). Something like this:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if ([touch.view isDescendantOfView:yourSubView]) {
        return NO;
    }
    return YES;
}

Edit: Please, also check @Ian's answer!

Swift 5

// MARK: UIGestureRecognizerDelegate methods, You need to set the delegate of the recognizer
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
     if touch.view?.isDescendant(of: tableView) == true {
        return false
     }
     return true
}

Problem

I need to implement a feature that will invoke some code when I double tap on the self.view (view of `UIViewController`). But the problem that I have other UI object on this view and I don't want to attach any recognizer object to all of them. I found this method below how to make gesture on my view and I know how it works. Right now I am in front of handicap which way to choose for create this recognizer ignoring subview. Any ideas? Thanks. ``` UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)]; [doubleTap setNumberOfTapsRequired:2]; [self.view addGestureRecognizer:doubleTap]; ```
