Вопрос
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?
Решение
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.
