What kind of object does @[obj1, obj2] create?
Looking at the Master-Detail Template in Xcode, in the App Delegate the SplitViewController‘s view controllers are set like so:
self.splitViewController.viewControllers = @[masterNavigationController, detailNavigationController];
I don’t know what the purpose of the @ sign is before the square brackets. Is this just how NSArrays are made when not using [NSArray arrayWithObjects:]?
It’s a new syntax feature. It’s syntactic sugar for creating an array (
NSArray) with the given objects.
