Need to close until showFromRect: animation finished.

[ReBruT]

If you press "back" on navigation bar until open animation finished, menu remains open on other view. It's simple to solve: simply comment "if (self.isAnimating) return;". It works good, but update from pods cleans it, and exist variable "BOOL waitUntilAnimationIsComplete;".

To close menu i'm used [menu close]; in viewWillDisappear:, maybe exist better way to do it?
