Why isn't there NSArrayController for the iPhone? Will there ever be an NSArrayController for the iPhone?
Why isn't there NSArrayController for the iPhone?
Because it's part of the Application Kit. The iPhone doesn't have Application Kit; it has UIKit instead.
Also, it exists on the Mac to complement Bindings, which doesn't exist on the iPhone.
Will there ever be an NSArrayController for the iPhone?
Ask Apple. Better yet, file an enhancement request. File one for Bindings while you're at it, since there's not much point in having NSArrayController without it.
