    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!!!
