    Here is a function which returns an image with different background of you choice.

    - (UIImage* )setBackgroundImageByColor:(UIColor *)backgroundColor withFrame:(CGRect )rect{

// tcv - temporary colored view
UIView *tcv = [[UIView alloc] initWithFrame:rect];
[tcv setBackgroundColor:backgroundColor];


// set up a graphics context of button's size
CGSize gcSize = tcv.frame.size;
UIGraphicsBeginImageContext(gcSize);
// add tcv's layer to context
[tcv.layer renderInContext:UIGraphicsGetCurrentContext()];
// create background image now
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

return image;
//    [tcv release];
}

    It will return you an image with blue background color. Happy Coding!!!
