How do I create delegates in Objective-C?

Question

I know how delegates work, and I know how I can use them.

But how do I create them?

Answer 1

//1.
//Custom delegate 
@protocol TB_RemovedUserCellTag 

-(void)didRemoveCellWithTag:(NSInteger)tag;

@end

//2.
//Create a weak reference in a class where you declared the delegate
@property(weak,nonatomic)id  removedCellTagDelegate;

//3. 
// use it in the class
  [self.removedCellTagDelegate didRemoveCellWithTag:self.tag];

//4. import the header file in the class where you want to conform to the protocol
@interface MyClassUsesDelegate ()

@end

//5. Implement the method in the class .m -(void)didRemoveCellWithTag:(NSInteger)tag { NSLog@("Tag %d",tag);

}
