问题
I have a question about the far right column of your Xcode project (image here)
Apple's documentation tells me this about that column:
Target membership. The column marked by the target icon indicates whether the file is included in the active target. If the checkbox next to a file is checked, then the active target includes that file.
So what if I have #import <Security/Security.h> in my .m file, do I still need to link it with the target membership? What if a .m file has that and it's not linked but the code works? Should I remove the line? Should I remove the framework?
Thanks.
回答1:
If you don't add it to the target, the compiler won't find the Security framework from the other files compiled under the same target. Targets are in a way separate projects that share some common settings.
