例如，您可以创建代表 FFT bin 行的小 png 文件，并根据音乐对它们进行动画处理。使用 cocos2d 这将非常容易，因为它已经提供了 API 来加载 png 文件并为它们制作动画。
再见
my suggestion is to exploit cocos2d http://www.cocos2d-iphone.org/ a very good framework enable developers to easily and quickly realize IOS graphical applications without dealing with OpenGL complexity.
You could for example create small png files representing rows of your FFT bins and animate them according to the music. This would be very easy with cocos2d because it already provides API to load png files and animate them.

一个非常好的框架可以让开发者轻松快速的实现IOS图形应用，而无需处理OpenGL的复杂性。
