当我尝试在Xcode中重构时，会出现警告，将文件添加到此工作区中目标的构build阶段

我看到这个消息，当我尝试通过重命名重构我的代码时，

***.h is not part of the build phase of any targets in this workspace and so can't be refactored. Add the file to the build phase of a target in this workspace, or make a selection in another file.

有时，只有在重新启动Xcode并重新打开项目之后，重构才能正常工作。但事后并不奏效。
