The most common reason for a message being "ignored" is because the receiver is nil. Step through your code in the debugger and see if self.delegate really is what you think it should be. By the way, it's a bad idea to have multiple calls to performSelectorOnMainThread: in a row like this. It's inefficient and gives you a large opportunity for brokenness by having other actions insert themselves in between the main-thread-perform actions. Instead, use performSelectorOnMainThread: only once, to call out to another method of yours which then performs all of the necessary main thread actions together.
