IPhone SDK: Wrappers, Delegates, and Data - OH MY!

Question

I'm writing a wrapper for another library and I would like to know the BCP for receiving the data returned via the delegate and returning that response to the instance that called the wrapper object.

// Original_Instance.m
BOOL example = [wrapperInstance getSomeData];


// Wrapper_Instance.m
[self thisWillReturnDataToTheDelegate];
return DataReceivedByDelegateToOriginalInstance;

Sorry if my example is unclear. Does anyone know what I'm talking about?

Thanks
