Functions of clean and clean build folder in xcode 4.5

Note: The conclusions in this article are incomplete and only applicable to xcode 4.5 (the version is not clear ).

Clean command

There is a clean command under the xcode menu "product. If you press the Alt key at the same time on the Windows platform, the clean command will change to the clean build folder. What are the functions of the two commands and what are the differences between them?

First, the function of clean is basically to clear the intermediate files, target files, and executable files during the compilation process, so that the project goes back to the pre-compilation. However, by analyzing a lot of articles on the network and testing in xcode 4.5, we can know that the system does not automatically clean every time you run the project, so the resource files will not be automatically updated. As a result, there is a quote like
