Laying out a view
In order to make a GUI, we need a strategy. For example, how do we control that a certain button should have the red color? How do we ensure that the background color changes when the user taps on the button? How do we position our different UI elements so that they look reasonable across different devices with different screen sizes, such as the iPhone and iPad?
