Color Me Crazy (or "When a Color Isn't Just a Color")

Ever need to use an image as a background, but can't figure out how? It's quite simple -- colors aren't always colors:

UIImage *patternImage = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"patternImage" ofType:@"png"]];

[myView setBackgroundColor:[UIColor colorWithPatternImage: patternImage]];
