.XIB WINDOW
In Xcode 4, Apple has integrated Interface Builder right into the Xcode IDE. You no longer need to launch Interface Builder as a separate application. To use Interface Builder, simply select any of the .xib files in your Xcode project. For example, if you have created a Single View Application project, there will be one .xib file in the project. Selecting it automatically launches Interface Builder.
When Interface Builder is launched, you should see something like Figure B-21.
Within this window are several items; and depending on what you have selected, you should see some of the following:
- File's Owner
- First Responder
- View, Table View, etc.
By default, the three items are displayed in icon mode; but you can also switch to display in document outline mode, where you can view some of the items in more detail. For example, Figure B-22 shows that when viewed in document outline mode, the View item displays a hierarchy of views contained within the View window.
