I have two controllers - how can I call the functions in them from the console?

Most of the time there is a hierarchy of UIViewController-s, and you can tap into those. starting at the UIWindow#rootViewController instance, and navigating through the childViewControllers. I would recommend either using BubbleWrap to access the window (App.window) or delegate (App.delegate). The SugarCube gem, which I maintain, provides an easy way to view the view or viewController hierarchies, too - the tree and tree root commands are available in the REPL for just this purpose.

I usually add a temporary global variable in the view controller to make it easier to access it from the console.

def viewDidLoad
  $temp_view = self
end

It is not pretty, but gets the job done.

The only way I can figure out how to do this is by using the UIApplication sharedApplication class method and drilling down from there, which is pretty icky.

(main)> UIApplication.sharedApplication.delegate
=> #<AppDelegate:0x6c8a800 @window=#<UIWindow:0x6e71280>>

Unfortunately to access the window I had to add an attr_reader :window to my AppDelegate class to access this private variable and then drill down even further to get at the view controllers:

(main)> vc = UIApplication.sharedApplication.delegate.window.rootViewController
=> #<TouchesViewController:0x8c747c0>

Now you should be able to call any public methods on that view controller.
