title: Xcode iOS UIView with tap gesture allowing input on subviews
body: <p>So I have a homepage view that people see when they first boot up the app, it has several different options. Yesterday I added a tutorial overlay, so the first time they open the app I have a view that is 0.5 alpha black and is fullscreen over the other view, this view has white text and arrows pointing to functions on the page. I attached a tap gesture recognizer to this view and its action is to call the next tutorial screen ( 3 in total). Afterwords they all are hidden and the app acts as normal. This all works, except even though my view is full screen, with User Interaction Enabled checked and a gesture tap recognizer, the gestures / touches on the sub view still work. So if I just tap some white space on the app the tutorial and tap gesture work as expected, cycle me through the pages etc and works. However if I accidentally press a sub view button or do a gesture from the subview it will do the action (take  you to a new page or w/e) </p>
  
  <p>So basically as far as I can tell my view despite being on top of the other and having a tap gesture recognizer attached to the view the sub views are still getting pressed, any ideas?</p>
