Dismiss modal view form sheet controller on outside tap

Question

I am presenting a modal view controller as a form sheet and dismissing it when the cancel button, which is a bar button item, is clicked. I need to dismiss it when I tap on

Answer 1

Here is my version that works for iOS 7 and iOS 8 and does not require conditional swapping of coordinates:

- (void)handleTapBehind:(UITapGestureRecognizer *)sender
{
    if (sender.state == UIGestureRecognizerStateEnded)
    {
        CGPoint location = [sender locationInView:self.view];

        if (![self.view pointInside:location withEvent:nil]) {
            [self.view.window removeGestureRecognizer:self.recognizer];
            [self dismissViewControllerAnimated:YES completion:nil];
        }
    }
}
