ios - WatchKit 基本文本动画

Question

是否可以重现我们在演示页面上看到的基本动画:http://www.apple.com/watch/health-and-fitness/

我们可以看到一些文本出现/消失。我想知道他们是否做到了，我们是否也可以做到，或者我们还没有获得这些方法...

我知道 watchKit 上的动画非常有限，但我们可以用 NSTimer 和 WKInterfacegroup 做点什么吗？

Can I use Core Graphics to generate images dynamically and then use them in a watch app? Can they be cached on the watch?

Yes, but the composition of any images using Core Graphics must take place on the iPhone as part of the extension. Once you have rendered the Core Graphics drawing context into an instance of UIImage you can then cache it on the watch using addCachedImage(_:name:) from WKInterfaceDevice.
