Even in this case, all you need to do is override -init to return the shared object. Apple's sample code, showing overrides to -retain, -release, and other such methods, just serves to hide bugs in the calling code.
I'd agree with that; I think it's generally more useful to raise an exception on dealloc to catch the memory management errors. The sample code also uses @synchronized in +sharedInstance, which turns out to be surprisingly bad for performance if you happen to call +sharedInstance in a loop.
There was a very long thread on Apple's singleton example a few years ago:
