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:]?

Answer 1

It's a new syntax feature. It's syntactic sugar for creating an array (NSArray) with the given objects.
