if you have an IBOutlet on an ivar like IBOutlet UIView *view; @property (nonatomic, retain) UIView *view; that object created by ib will be managed by ib, but what if you have, UIView *view; @property (nonatomic, retain) IBOutlet UIView *view; does ib now use your setter to set that object? that would mean the setter has added +...
