iOS 7 - Strange behaviour when panning the top view controller

[eduardocoelho]

iOS 7 introduced new system-wide gestures, such as navigating back to a previous view controller through a 'swipe' gesture.
Looks like the current implementation does not expect that (e.g.: the private readonly UIPanGestureRecognizer _panGesture; property).

I'm also facing a strange behaviour: If I pan the top view controller all way to the right and then still try (insist) panning the top view controller to the same direction (right) I get the unexpected black background in the middle of the screen, as shown in the screenshot:

Will look into this after upgrading to the latest iOS sdk's. If i remember correctly you can quickly solve this by manipulating the widths and offsets but i will look into the calculations to take the correct screen widths. I assume you are developing for iPad?

I'm developing for both iPhone and iPad. The behaviour applies for both platforms.

I also noticed a crash while panning the navigation bar. Currently I just commented private readonly UIPanGestureRecognizer _panGesture; to avoid crashes on my production app.

Thanks for the feedback will dig into it soon, let me know if you find something else in the meantime
