I currently try to exclude my In-App Purchase logic in an App of mine to make it reusable in other Apps of mine or even put it on a public git repository for others to use. For this purpose I follow this guide of creating a framework in XCode.
But in step 2 I have to set the Target Membership of my .h file to public. The problem is, that in my Xcode (v 4.5) I can't see any visibility when the .h file is clicked (and also not when I click other files like .m ones). It looks like that:
What am I doing wrong there?
I came across this same problem and found your question an hour after it was posted but here is what I have found. In Xcode 4.4 the ability to change the target membership, and visibility, for header files was removed so this tutorial will not work as written.
Instead of changing the target membership visibility you can add a "Copy Headers" build phase to the target you made in step 1 (Serenity in the example). This will have 3 sections for Public, Private, and Project headers. Just click the plus at the bottom and the headers you want to be public to this step. By default they are put in the Project section but you can click and drag them to the Public section.
The rest of the tutorial should work fine from there.
Edit: Just noticed that in my own project, after adding the copy headers build step, that the target membership can be selected for header files so the tutorial works as written. Though it seems to act a little strange with my framework header. In any case, changing the visibility in the build phase is reflected under target membership and vice versa
Build Phases -> Add Build Phase -> Copy Bundle Resources (in case you don't have it) Then drag and drop your file there... Good luck ;)
