Question

After creating an Xcode project from the iPad “master/detail” storyboard template, I cannot seem to find the UIGestureRecognizer instance that’s responsible for the Mail-style swipe to show the master view in portrait mode.

I need to do this in order to make it ignore touches on certain UI elements, but it doesn’t seem to be handled by any of the 4 gesture recognizers returned by the gestureRecognizers method of the master view. When I set a delegate on them, its functions only get called when interacting with the master view itself, and not with a swipe on, e.g. the detail area. The detail view returns an empty array from gestureRecognizers.

A project-wide search for “gesture” reveals nothing, and I see no gesture recognizers in the storyboard. Where is this handler created and managed in the default Xcode “master/detail” template, and how can I access it in order to set a delegate?

Answer 1

I expect it is on the split view controller itself rather than the master or detail view controllers. You can turn it on or off using the presentsWithGesture property (5.1 and later only).
