View animations are suddenly gone after using layer animations

Question

I'm using CABasicAnimation and CATransaction to animate some layers in my custom UIView.

However, when after that returning to the rest of my app using a navigation controller's back button, the navigation controller does not animate anymore. Not even when then going to any other view.

I am using an iPad with iOS5.

Answer 1

I was able to workaround this by calling

[UIView setAnimationsEnabled:YES];

in my viewDidDissapear and viewWillDisappear methods.

Really strange since I am never disabling view animations anywhere in my code.
