Answer 1

Can you tell us which class is creating the GoogleDocsViewController? Check that class' header (.h file) and see if it implements the GoogleDocsViewControllerDelegate.

Basically the delegate is the object which will listen to interesting events from the GoogleDocsViewController and it should implement the protocol mentioned so it "knows" which actions to perform when the events are fired.
