I just notice that Activity holds a strong reference to the ActivityViewController and this leads to all 3 instance are not being deallocated after calling ActivityViewController dismissViewController.
I added dealloc method to all 3 instances to print a dealloc message and tried with the Mail activity, i didn't see any of the dealloc messages.
