POButton background and gradient change since iOS6
text
Body
copied!<p>For an app I had to create a <code>UIButton</code> filled with a gradient and a background image. Everything worked fine until I upgraded the OS from iOS 5.1 to the recently released iOS 6. </p> <p>Here are two screenshots from the simulator : </p> <p><img src="https://i.stack.imgur.com/QyGHF.png" alt="screenshot with iOS 5.1"></p> <p><img src="https://i.stack.imgur.com/Zp3Xa.png" alt="Screnshot with iO 6"></p> <p>Well, the first screenshot shows what I need (and did), you can see a brown background and the grey radient. </p> <p>Below is the screenshot with the same buttons but with iOS 6 running. As you can see the gradient has vanished and a strange white strip has appeared at the bottom of the <code>UIButton</code>.</p> <p>I've looked if this is a bug or something but I've found nothing, maybe someone here has faced the same problem? Here is my code for gradient</p> <pre><code>CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.frame = btnCountry.bounds; UIColor *colorTop = [UIColor colorWithRed:.992f green:.992f blue:.992f alpha:1]; UIColor *colorBot = [UIColor colorWithRed:.788f green:.769f blue:.745f alpha:1]; gradient.colors = [NSArray arrayWithObjects:(id)[colorTop CGColor], (id)[colorBot CGColor], nil]; gradient.borderColor = [UIColor colorWithRed:.545f green:.506f blue:.459f alpha:1].CGColor; gradient.borderWidth = 1; gradient.masksToBounds = YES; gradient.cornerRadius = 11; [[btnCountry layer] insertSublayer:gradient atIndex:0]; </code></pre>
