I banged my head against figuring out how to make use of third-party frameworks. Unfortunately, this seems like a task that most developers expect users to instinctively know how to do and never explain it otherwise. I was somewhat frustrated and having trouble getting my project to make use of the third party Framework for both compiling and running. After some banging my head on the wall, a post on StackOverflow and a few bruises later I got it working.
The first thing that I needed to do was build the framework. The particular Framework I am using is MPOAuthConnection which provides an SVN link and a project. I, therefore, needed to build the Framework in that project. Xcode is nice enough to put Products in the item list. I simply dragged the MPOAuth.framework product from the MPOAuthConnection Project to my Celery Project. Dropping it into the Linked Frameworks section and choosing to copy the files.
Using the proper imports, this admittedly tripped me up a bit, because I was working in the project and doing “file.h” imports rather than the proper <library/file.h> imports, my project would compile.
However, I was getting odd errors on running, where it couldn’t find the files needed (and some strange memory problems). Turns out, when you add a new Framework, you also have to have the build system copy the framework into the Application product. To do this, you need right click on the target for your application, Add -> New Build Phase -> New Copy Files Build Phase. The only setting that needs to be set is the Destination must be set to “Frameworks”.
Here is the key element that I could not figure out for about an hour. You must drag the Framework from the Linked Framework to the new Build Phase you just created.
Viola! You should be set.
