We may use arc when developing our own apps. If we want to use some non-arc open-source code, we will encounter problems during compilation, A good solution is to compile some files using arc, while other files are not compiled using arc. How can this problem be solved?

Find the file to be specially processed in the compile source in build phase, and add the compilation option (compiler flags). If the arc file is added to a non-arc project, add-fobjc-arc as the compilation option. Otherwise, add-fno-objc-arc if a non-arc file is added to the ARC project.
