Hi all. I'm writing an iPhone app that interacts with a database over the Web using XML, and PHP on the server side.
Obviously, delays in downloading data are frequent, so I'm using Grand Central Dispatch to do a bunch of it asynchronously. This brings up a basic question: How do I notify all concerned views that the underlying data store has changed? I could create some kind of multi-delegate or "subscriber" system where view controllers join a list to be notified. Is that how people are doing it, or is there some Cocoa mechanism that I should be using? Thanks for any insight. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
