Instruments reports this a memory leak (98.6%, whatever that means):
[[NSNotificationCenter defaultCenter] postNotificationName:kNotificationSomeNotification object:self];
"self" is a subclass of UIImageView. Is including "self" in the notification causing a memory leak? If so, how do you resolve it?
Better check your notification observer. The cause of memory leak might be there.
Memory leaks are almost always it is not safe. Check again are there leakage accurately!? You can do this by using deleaker.
