问题
My project contains XMPPFramework which contains a file that has to be used with ARC. But my project is Non ARC and cannot be converted due to certain other libraries linked to it.
How do I force the compiler to use ARC only on a certain class ?

It is the inverse problem of this question. The difference is that you would use -fobjc-arc instead of -fno-objc-arc.
