Question

I am trying to add a delegate to a CALayer so I can know when the animation sequence is complete. It’s animating 40 sublayers around the screen. Once I add the delegate as I do below, all the animation stops on the CALayer.

Here is my code:

@protocol NIArticlesLayerDelegate;

@interface NIArticlesLayer : CALayer {
    id<NIArticlesLayerDelegate> delegate;
}

@property (nonatomic, assign) id<NIArticlesLayerDelegate> delegate;

@end



@protocol NIArticlesLayerDelegate <NSObject>

@optional
-(void)itemAtCenter:(id)item;

@end

Answer 1

Checking the CALayer Docs, CALayer already has a property called delegate which MUST be assigned to the owning view. Try changing the name?
