Whether I should use @property(nonatomic,copy) or @property(nonatomic,strong) for my (NSString *) attr in An object?

Question

@interface PaneBean : NSObject

@property(nonatomic,copy) NSString *name;
@property(nonatomic,copy) NSString *type;
@property(nonatomic,assign) NSInteger width;
@end
         


        

Answer 1

Strong indicates composition, while Weak indicates aggregation.

Copy means that a new object is to be created before the contents of the old object are copied into the new object. The owning object, PaneBean in this case, will be composed of the newly created object.
