From Resource Programming Guide,

Objects in the nib file are created with a retain count of 1 and then autoreleased. As it rebuilds the object hierarchy, UIKit reestablishes connections between the objects using setValue:forKey:, which uses the available setter method or retains the object by default if no setter method is available.

Not that the available setter method is generally a retained one. So if you are not using ARC then you need to release IBOutlets. one suitable place to release is the dealloc method.
