Adding A Background Image In Interface Builder
You could also use this Statement in Code.
[self.view setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"foo.bar"]]];
Just drag-and-drop the image from Finder to the extreme left pane of your Xcode window (where the list of files is shown). Now open your xib file and locate the image in your media library. Just drag-and-drop the image from the media library to your view. Adjust the size of the image as you need.
