ImageBrightness....with simple one Method

- (UIImage *)imageNamed:(UIImage *)newimg withColor:(UIColor *)color{

    // load the image

//    NSString *name = @"badge.png";

    UIImage *img = newimg;

    // begin a new image context, to draw our colored image onto

    UIGraphicsBeginImageContext(img.size);

    // get a reference to that context we created

    CGContextRef context = UIGraphicsGetCurrentContext();

    // set the fill color

    [color setFill];

    // translate/flip the graphics context (for transforming from CG* coords to UI* coords

    CGContextTranslateCTM(context, 0, img.size.height);

    CGContextScaleCTM(context, 1.0, -1.0);

    // set the blend mode to color burn, and the original image

    CGContextSetBlendMode(context, kCGBlendModeColorBurn);

    CGRect rect = CGRectMake(0, 0, img.size.width, img.size.height);

    CGContextDrawImage(context, rect, img.CGImage);

    // set a mask that matches the shape of the image, then draw (color burn) a colored rectangle

    CGContextClipToMask(context, rect, img.CGImage);

    CGContextAddRect(context, rect);

    CGContextDrawPath(context,kCGPathFill);

    // generate a new UIImage from the graphics context we drew onto

    UIImage *coloredImg = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    //return the color-burned image

    return coloredImg;
