Attempt to present UIViewController on UIViewController whose view is not in the window hierarchy

Question

Just started using Xcode 4.5 and I got this error in the console:

Warning: Attempt to present < finishViewController: 0x1e56e0a0 > on < ViewCont

Answer 1

I had this issue, and the root cause was subscribing to a button click handler (TouchUpInside) multiple times.

It was subscribing in ViewWillAppear, which was being called multiple times since we had added navigation to go to another controller, and then unwind back to it.
