I've been trying to dismiss the modal form sheet view on outside tap on iOS 8 with no luck,
I've tried this code
UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)];
[recognizer setNumberOfTapsRequired:1];
recognizer.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view
[self.view.window addGestureRecognizer:recognizer];
- (void)handleTapBehind:(UITapGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded)
{
CGPoint location = [sender locationInView:nil]; //Passing nil gives us coordinates in the window
//Then we convert the tap's location into the local view's coordinate system, and test to see if it's in or outside. If outside, dismiss the view.
if (![self.view pointInside:[self.view convertPoint:location fromView:self.view.window] withEvent:nil])
{
// Remove the recognizer first so it's view.window is valid.
[self.view.window removeGestureRecognizer:sender];
[self dismissModalViewControllerAnimated:YES];
}
}
}
But it doesn't detect outside view clicks, any suggestions ?

There are actually two problems in iOS 8. First, the gesture recognition does not begin.
I solved this by adding the
UIGestureRecognizerDelegate
protocol and implementingAlso, don't forget to register the delegate with
Now the gesture recognizer should recognize gestures and the target method (
handleTapBehind:
) will be called.Here comes the second problem in iOS 8:
locationInView:
doesn't seem to take the device orientation into account ifnil
is passed as a view. Instead, passing the root view works.Here's my target code that seems to work for iOS 7.1 and 8.0:
