@interface CustomObject : NSObject

{

id target;

SEL selector;

}

- (void)setDelegate:(id)aTarget selector:(SEL)aSelector;

- (void)setDelegate:(id)aTarget selector:(SEL)aSelector

{

self.target = aTarget;

self.selector = aSelector;

}

// 콜백 메소드를 호출함

if(target)

{

[target performSelector:selector withObject:result_obj];

}

<< 콜백 메소드를 호출 당하는 쪽 >>

[custom_obj setDelegate:self Selector:@selector(CallBackMethod:)];

- (void)CallBackMethod:(id)result_obj
