UINavigationController: View not popping, but title pops

I have a UINavigationController and a UIViewController pushed onto the stack with pushViewController. When I click the default back button, the title appropriately animates away, but the view does not pop. Is there something that I am missing?

There is a solution here: UINavigationController not popping view on back bu开发者_高级运维tton, but this involves overwriting the button itself. It doesn't seem to be very good design. Isn't the back button supposed to pop the view automatically?

Could be due to an exception occurring - CoreAnimation eats the exceptions, so carefully check your console output for error messages.
