One interesting thing to note about IBOutlet and their connection to Interface Builder. If the field being defined as an IBOutlet does not have an explicit “setting” method, either by manually writing it or by using @property and @synthesize, the route to connect the Nib’s definition to this field in the file is setValue:forKey. This method retains the field that is set as an outlet. Therefore, even though you didn’t retain the field anywhere in your code, you need to release it in your dealloc method.
So, I typically just make sure all outlets are properties.
