Answer 1

Does your class still exist in memory?

If your class goes away before the performSelector fires, do you wind up sending the message to nil (which would cause nothing to occur). You could test this by dropping an NSLog into your dealloc()

You mentioned threads. If your performSelector isn't called from the MainThread it could cause issues (UI things should be done on the main thread).
