头文件自动补齐

在stackoverflow上找到了解决办法:

Go to the Target > \”Build Settings\” tab and find the \”User Header Search Paths\” setting.

Set this to \”$(BUILT_PRODUCTS_DIR)\” and check the \”Recursive\” check box.

Now the built target will search the workspace’s shared build directory to locate the linkable header files.

简单说就是这么几步:

• 选择Target -> Build Settings 菜单，找到\”User Header Search Paths\”设置项
• 新增一个值"${SRCROOT}"，并且选择\”Recursive\”，这样xcode就会在项目目录中递归搜索文件

自动补齐功能马上就好使了。
