Here is what i have:</p> <pre><code> //Loading Image from Url and adding it to navigationbar NSString *urlString = [NSString stringWithFormat:@"http://someurl.com/%@.gif",imageId]; NSURL *imageUrl = [NSURL URLWithString:urlString]; UIImage *myImage = [UIImage imageWithData: [NSData dataWithContentsOfURL:imageUrl]]; UIButton* button = (UIButton *) myImage; UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithCustomView:button]; self.navigationItem.rightBarButtonItem = buttonItem; </code></pre> <p>This works as long as i take a local image and allocate the image view like this:</p> <pre><code>UIButton* button = (UIButton *) [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"myLocalImage.png"]]; </code></pre> <p>The error i get is: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImage _setAppearanceIsInvalid:]: unrecognized selector sent to instance 0x6876df0'</p> <p>Anybody can help? (Or is this too nasty of a hack anyway?) Thanks a lot!</p> <p>Ps: heres the original question for the adding image to navigation bar: <a href="https://stackoverflow.com/questions/844416/how-to-display-an-image-in-the-navigation-bar-of-an-iphone-application">how to display an image in the navigation bar of an iPhone application?</a></p> <p><strong>Edit:</strong> Theres an error in the code: Should be like this i guess:</p> <pre><code>UIButton* button = (UIButton *) [[UIImageview alloc] initWithImage:myImage]; </code></pre> <p>Anyway, i dont get an error anymore now, but the image does not appear...</p>
