AppDelegate confusion when converting code to Marmalade

Question

I'm converting standalone iPhone code for use as a Marmalade extension (a cross-platform mobile dev kit). You don't need to know about Marmalade though for this question.

My issue is figuring out what to do with AppDelegate. The stand-alone app defines AppDelegate, but a Marmalade extension is callback based and Marmalade has probably already defined its own AppDelegate. So what do I do when my extension is called back? I don't think I can define another AppDelegate can I? How? And I don't want to replace the one Marmalade already defined. There are Marmalade calls I can make to retrieve the UIApplication and pointers to the UIViews Marmalade defines, but I don't know how to get my own AppDelegate in there. Can I extend the one that Marmalade already defined somehow?

I come from a C/C++ background and this is my first attempt at Objective C, and so far it's got me very confused.

Got it sorted now. My confusion had the better of me and it turns out the way the original code used AppDelegate was not vital, so I was able to do away with it for the Marmalade extension and get things working without it.
