Weird. i just did a project-wide search for "performSelector". All instances where I use this is to direct a view controller to perform another action after something did happen. I do an NSLog() in each controller's viewDidUnload: and didn't see any of those. So, the chance that the object would be deallocated seems slim to me. Instances are like when a view appear, I want to start a download from the server but not immediately, just a second after the view did appear. The view controllers where I use my performSelector:withObject:aferDelay: should still be there when the perform is fired. I don't pass any object for withObject:. Like I said, it's just used to delay some actions strictly in view controllers. That is strange...

-Laurent.
