If you write correct accessors for all outlets, then the retain/release memory management is entirely handled in one method.  the -set retains the new value and releases the old value.
 
Any confusion regarding memory management for IB outlets seems to stem from failure to write the accessors and reliance on syntactic sugar.  Just remember that
 
@property (nonatomic, retain) IBOutlet UILabel *label;
 
results in synthesis of the appropriate accessor methods.  It does nothing more than save you some typing and document your intention.  The -set method that results from the above property declaration retains the new value and releases the old value.  The memory management is therefore all handled in one place just the way it should be and the way you want.
 
So what's the problem again ?
