    text
    copied!<p>I've been trying to set the background image of a rect button as a .png file I have on my web server. I've declared the button in the view controller .h and added this under .m viewdidload:</p> <pre><code>[mybutton setImage: [UIImage imageNamed: @"http://www.myserver.com/index_files/stacks_image_14.png"] forState: UIControlStateHighlighted]; </code></pre> <p>but nothing shows in the button. I've been reading on NSSURL to see about calling in images before I try to assign them to objects, but I'm a little stuck at the moment.</p> <p>Thanks for any help!</p> <p>EDIT: New Code I've tried:</p> <pre><code> NSURL *myurl2 = [NSURL URLWithString:@"http://www.myserver.com/bigoaks.png"]; NSURLRequest *request2 = [NSURLRequest requestWithURL:myurl2 cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10.0]; NSURLConnection *connection2= [[NSURLConnection alloc] initWithRequest:request2 delegate:self]; NSString *mystring2 = [NSString stringWithContentsOfURL:myurl2 encoding:NSUTF8StringEncoding error:&amp;error]; [mybutton setImage : mystring2]; </code></pre> <p>Still seem to get "No visible @interface for UIButton declares the selector 'setImage:'</p> <p>Thanks again for all the assistance!</p> <p>EDIT 2:</p> <p>Got it! Thanks for all of the help guys-- here's the final code to help any others:</p> <pre><code>NSURL *myurl2 = [NSURL URLWithString:@"http://www.myserver.com/bigoaks.png"]; UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:myurl2]]; [mybutton setImage:image forState:UIControlStateNormal]; </code></pre> <p>Using this tutorial: <a href="http://mobiledevelopertips.com/cocoa/download-and-create-an-image-from-a-url.html" rel="nofollow">http://mobiledevelopertips.com/cocoa/download-and-create-an-image-from-a-url.html</a></p>
