问题 I need you to humor me during this question. This is somewhat pseudo code because the actual situation is quite complex. I wouldn't load an image this way unless I needed to. Assume that I need to. NSURL *bgImageURL = [NSURL URLWithString:@"https://www.google.com/images/srpr/logo3w.png"]; UIImage *img = [UIImage imageWithData:[NSData dataWithContentsOfURL:bgImageURL]]; [self.anIBOutletOfUIImageView setImage:img]; but I crash out with -[__NSCFData _isResizable]: unrecognized selector sent to

问题 In a program I am creating for iOS 5, I am experiencing unexpected behavior with the checkResourceIsReachableAndReturnError method of NSURL.

问题 I have some URLs in my app which takes the user to Safari browser through openURL API. My aim is to sent the auth token to Safari from the app, so that user will be logged in by using this token.
