Can you associate child view controllers to a custom container view controller in Storyboard?

I think what you're asking here is how to connect a view controller in one scene to an outlet of a view controller in a different scene. I don't believe that's possible, perhaps because the storyboard machinery may not have all the scenes in a storyboard loaded at the same time.

You're probably asking this because you want to pass some information from one view controller to another as you segue from one scene to the next. The way to do this when you're working with storyboards is to override -prepareForSegue:sender: in one or both view controllers affected by the segue. The UIStoryboardSegue object provided in the segue parameter has sourceViewController and destinationViewController properties, and also an identifier property. You can use these properties to identify the segue that's about to transfer data between the view controllers.

Ray Wenderlich's blog has a nice two-part tutorial on using storyboards that may help you:

• Part 1 covers setting up a storyboard project, adding scenes, and creating segues.

• Part 2 deals with using segues to transition between scenes, including the prepareForSeque method mentioned above.

iOS 5 allows multiple view controllers to be active in the same scene (although one should still be in charge), so a single scene in your storyboard might have several controllers. You can use outlets to connect these controllers to each other, and you can configure those connections the same way you did in IB: control-drag from one controller to another in the same scene. The usual outlet list will pop open to let you choose which outlet to connect.
