I have a strange problem with a memory leak (the only one ;-) ) in my iPhone app: I don't know where I have to look for the cause of this leak... the strange thing is that this, exactly this leak also shows up if I create a new navigation-based app and just run it without any changes.

I'm trying to chain animation events. The application I'm coding for work has a multiple choice quiz. First you pick your multiple choice answer. The quiz view fades away.

I'm trying to compare two UIImages from the file system to see if they are the same. Obviously, I can't use NSObject's hash method, since this returns a hash of the object, and not the actual image data.
