If you want to create an iOS app you have 3 options:
- to create an iPhone app (which generally runs on iPod touch as well)
- to create an iPad app
- to create an Universal app (the same code gets installed and executed both on iPhone and iPad)
Xcode is very nice with developers, and therefore gives us some pre-defined templates for starting to create iOS apps. One of the simplest and most common used is "Single View Application". This generates a AppDelegate class, and also a ViewController class, which has a ViewController.xib GUI file associated with it.
Developers are calling .xib files xibs, or nibs. (nibs come from History, xib files were initially with .nib extension, so generally people use these interchangeably).
In Xcode we have a section named Objects Library, where we have all the GUI elements we can put on the screen. Simply drag-and-drop the ones you need on the main view, and they will be there, and appear when you run your app in the Simulator, or on the Device.
You can change the details/properties of the visual elements from the Attributes' Inspector section, which you can find on the left-top side. Also you can customise those elements in your code(which is not so common however).
