How to steal touches from UIScrollView? http://stackoverflow.com/questions/4629499/how-to-steal-touches-from-uiscrollview of hitTest withEvent actually returns the subview that should receive the touch. Instead it uses gesture recognizers to intercept the touches. So the third thing I attempted was to implement my own gesture recognizer and cause it to fail.. it to fail if the touch was outside of the picker view and otherwise succeed. Then I set all the scroll view's gesture recognizers to fail unless my gesture recognizer failed using the following code for UIGestureRecognizer gestureRecognizer in self.tableView.gestureRecognizers.. after 150 ms. I'm thinking that I should be able to write a similar recognizer that causes the scroll view's default recognizers to fail and instead of delaying the touches immediately sends them to the picker view. So if anyone knows how to write such..
