iOS 开源代码**
搞了好久的ios开发，过程遇到各种各样的问题，基本都是靠搜索，然后下载别人的开源代码来研究，下面列出一些常逛的ios开源代码网站，分享一下。
cocoacontrols.com 收集了很多UI控件效果代码，缺点是需要代理，而且代码分类不够好。
code4app.com，国内有个类似的，大部分代码来自github，但是做了中文翻译和效果截图，支持搜索，比较好用。缺点是代码还没有那么多。
www.mopapp.com/directory/best-resources-iphone-developers 基本汇集比较热门的iOS免费开发资源，大多数代码我都是从这里面找的。
cocoalit.com 也是个十分齐全的代码库，分类十分清楚。
