运动图像一起predetermined路径？ [英] Moving image along predetermined path?

问题描述

是否有可能将图像设置成随着一个按钮的iPhone SDK推一个predetermined轨迹运动？我不是在寻找任何幻想。我工作的一个简单的概念，但是这将节省大量的动画作品。

Is it possible to set an image into motion along a predetermined path with the push of a button in iphone SDK? I'm not looking for anything fancy. I working on a simple concept, but this would save a lot of animation work.

推荐答案

是的。您可以通过创建一个 CAKeyframeAnimation 动画沿路径任何的CALayer并分配 CGPath 到路径属性。请参见由比尔Dudney 一个例子这个博客帖子。

Yes. You can animate any CALayer along a path by creating a CAKeyframeAnimation and assigning a CGPath to its path property. See this blog post by Bill Dudney for an example.
