The setImageFailed: method is not declared anywhere in the AsyncImageView library. My guess is that either:

1. You have implemented your own handler for the AsyncImageLoadDidFail NSNotification, and in the logic you've written for that function, you are calling setImageFailed: on the wrong object.

Or

2. You are calling loadImageWithURL:target:success:failure:, and passing @selector(setImageFailed:) as the failure argument, but you've set the target object as an image that doesn't implement setImageFailed:.

Nick,

Thanks for the quick response. setImageFailed is there in AsyncImageView library, you can find that method next to setActivityIndicatorStyle method

@harishios I see a setImage: method and an imageFailed: method, but not setImageFailed:
