Dealloc not being called on ARC app

Question

I have a UIViewController that is pushed onto a container controller and then popped off, and using the allocations instrument, I can see that the view controller is destroy

Answer 1

If dealloc is not being called by the VC, then I would bet there is a circular reference somewhere in your code, which is preventing ARC from calling dealloc.

Some things to check:

1. Do you have an object instantiated that references back to the VC?
2. If you need to reference the VC be sure you have used '__unsafe_unretained' attribute or 'weak' (iOS5+) so that the retain cycle does not occur.

I was nipped in the butt when my delegate declarations did not utilize __unsafe_unretained.
