In Objective-C problem in creating view delegate

Tarun Kumar 2194 25 Sep 2015

I have a problem with my delegate, when I was trying to create a delegate protocol in a custom UIView.

Here is my code:

@protocol MyViewDelegate
@optional 
- (void) myViewDidInitialize:(MyView *)myView;
@end
 
@interface MyView : UIView {    
@private
}
@property(nonatomic, assign) id<MyViewDelegate> delegate;
@end

This doesn't work because the MyView interface has not been declared at the time of the MyViewDelegate declaration. I was tried to adding a prototype before the @protocol:

@interface MyView;

But this just drives the compiler nuts. How am I supposed to do this?

Here is your problems solution, I think you can forward the declared protocol:

@protocol MyViewDelegate;
@interface MyView: UIView{
@private id<MyViewDelegate> delegate;
}
@property(nonatomic, assign) id<MyViewDelegate> delegate;
@end
@protocol MyViewDelegate
@optional -(void) myViewDidInitialize:(MyView *)myView;
@end
