When creating a single view application in Xcode and dragging a UIButton in, for example, the button shows up when running the application in the iPhone simulator. However, when creating a new UIViewController class and setting that as the custom class of the view controller in the storyboard file, just a black screen is shown in the iPhone Simulator.
What did I do wrong?
I bet the Xcode template included the loadView method in your controller class. You need to delete that as you only override that method when you are creating your interface via code.
