title: How to delay a CABasicAnimation?
body: <p>I have a <code>CABasicAnimation</code> and want to start it after a delay. In UIKit I can specify delays. The <code>CAMediaTiming</code> protocol has a <code>timeOffset</code> property but I can't see an effect. My next try is to use GCD to delay it but it feels like overkill.</p>
