on iOS7 if you pushViewController animated, and then popToRootViewController not animated, and then again pushViewController animated, you will see

nested pop animation can result in corrupted navigation bar
nested push animation can result in corrupted navigation bar

Hello,

I'm trying to use the BufferedNavigationController programmatically, outside of IB. I simply replaced all my references to UINavigationController to BufferedNavigationController. So far, my calls to push and pop aren't doing anything.

Any idea what could be going wrong? Does the class work without using IB?

Thanks!

Hi.

With iOS 7, a pop gesture was introduced. Basically, if you have several controller on your navigation stack, swiping left to right will pop the view controller.
But if you start popping, then cancel (by, for instance, swiping back), then the - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated method is not called, and you are always marked as "transitioning".

BufferedNavigationController seems to be using delegate property itself. So, upon setting up a delegate to it, it does not do any transition.
