自动联想补齐代码

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。

先这么写试试, 有空检验一下
