Is this also true when using completion blocks? I don't implement the delegate.

The docs seem quite explicit that the delegate method will be called immediately. If you're telling me otherwise, as you seem to be, then I'd say you've identified a problem in the docs. > > <https://developer.apple.com/bug-reporting/> > > Share and Enjoy > -- > Quinn "The Eskimo!" <http://www.apple.com/developer/> > Apple Developer Relations, Developer Technical Support, Core OS/Hardware > > > > _______________________________________________ > Do not post admin requests to the list.
