Hello.
I found a few examples of creating UIGestureRecognizer programmatically but
since they're in IB now, I thought why not using them there. So, I have an
Xcode 4.4 iOS 5.1 project using ARC with a UITableViewCell that contains a
UIScrollView, among other things, which scrollview contains an UIImageView. I
want the user to be able to zoom the image view, obviously. So, I dragged an
instance of UIGestureRecognizer into my controller's segue (scene?). I then
connected its action to an action method in my view controller. I then dragged
a connection from the scrollview to the gesture recognizer and connected it to
the gestureRecognizers of the scrollview. Everything seems to be OK. But when I
launch my app in the simulator, as soon as the view is to appear, it crashes
more or less randomly with:

The gesture recognizers is configured with 1 tap, 1 touch, state enabled,
events canceled in View, delayed begin and delayed end.
What am I missing?
