title: How to I create a MainWindow.xib in Xcode 4.2 in an iOS application?
body: <p>I am just starting out learning to build interfaces, but the book I am following is a little dated and it says that Xcode should create it for me with my new project, however it didn't. So now I need to link my buttons to my app delegate, but I can't because it isn't showing up when I right click on my buttons. And yes, I did define my methods and instance variables.</p>
