Best practices when importing class files in xcode

Question

I'm working with xcode and I have classes associated with other projects that I want to be included in new projects. I realize that the #import will do the job technically (although what should i do if it's out of the project root folder). But what do I do if I want to include the class "properly" --basically so i can double click and edit out of the main project window where you can see all your files and such.

I guess I'm just looking for the best and/or proper way to include/import (into the project) .h and .m files that I've already created outside of the current project I'm working on. Taking into consideration that I may want to modify the class from the original without subclassing. Hopefully this makes sense.

Thanks,

Nick

Answer 1

Might be worth thinking about how to make the classes into a private framework - then you can import that as another dependency each time. Alternatively you could use a separate version control system location to store the shared classes and just check that out into the project folder.

Answer 2

Xcode project file organization doesn't reflect the data files on disk. Files can be added to a project from anywhere in the file system. When you add the files, choosing not to copy the files to the current project's directory means that the original files are used. Selecting one of these files in Xcode for editing will alter the original file in that other project. When returning to that other project, Xcode will use the edited files in any further work.

This type of use can be quite handy while working on multiple projects with some shared code. Yet, it can also cause headaches for a versioning system.
