Answer 1

This is an excellent thread. Here's my experience: I messed up with the retain/assign keyword on a property declaration. I said:

@property (nonatomic, assign) IBOutlet UISegmentedControl *choicesControl;
@property (nonatomic, assign) IBOutlet UISwitch *africaSwitch;
@property (nonatomic, assign) IBOutlet UISwitch *asiaSwitch;

where I should have said

@property (nonatomic, retain) IBOutlet UISegmentedControl *choicesControl;
@property (nonatomic, retain) IBOutlet UISwitch *africaSwitch;
@property (nonatomic, retain) IBOutlet UISwitch *asiaSwitch;
