Can someone explain this Objective C @property syntax?

Question

Reading over some example Objective C code just now.

@property (nonatomic, strong) IBOutlet UILabel *descriptionLabel;

I understand that here we're declaring a property named descriptionLabel. The property has two attributes: nonatomic and strong.

What I don't understand is there are two type definitions ... IBOutlet UILabel ...

Can anyone explain why and what the implications are of two type definitions?

I think IBOutlet is #define'd to be a "empty". This is basically used as an indicator by Interface builder to indicate properties that can be set. — akhisp, Feb 12 '12 at 21:47
