At compile time, the headers need to have been #included. It looks like CAAudioFile.h does include <AudioToolbox/AudioToolbox.h>, so I'm not sure why it wouldn't pick up the AudioFile declarations. Unless there's something different about the header layout on iPhone.
UInt32 nFrames = inNumberFrames;

Um, PullBuffer is a method, not a function. You have to call it through an instance of the class, i.e. myfile->PullBuffer. (Unless this snippet is part of a method in a class that subclasses CAAudioFile? In that case, we'd need to see more of the code.)
