I am going through the Hello World iOS tutorial, and I am having some problems. When I launch it in the simulator, the app is loading off center, and when I click the translate button, a MonoTouch.Foundation.MonoTouchException is being thrown. It looks like TranslateButton and translatedNumber are unknown identifiers in ViewController.cs. I copied the text word for word for ViewController.cs from the tutorial; it did not have any code that declared those variables.. Isn't that done by the Storyboard? What am I missing? The only change I have made to the previous zip file was setting the storyboard for the Main Interface as suggested to get the simulator working.
