I got this error when I integrate admob to my app
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSURLResponse statusCode]: unrecognized selector sent to instance
-[NSObject(NSObject) doesNotRecognizeSelector:]
[AdMobURLDownload connection:didReceiveResponse:]
it does not crash if I don't implement
- (void)didReceiveAd:(AdMobView *)adView;
