Add tint to UIImage

I have been working on a SDK that allows user to customize colors for images. In many cases, I need to add an image to a button with different color at run time. So using just tintColor is not going to work. The following method will mask an image with the color you define.

- (UIImage *)maskWithColor:(UIColor *)color
    CGImageRef maskImage = self.CGImage;
    CGFloat width = self.size.width * self.scale;
    CGFloat height = self.size.height * self.scale;
    CGRect bounds = CGRectMake(0,0,width,height);
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    CGContextRef bitmapContext = CGBitmapContextCreate(NULL, width, height, 8, 0, colorSpace, kCGBitmapAlphaInfoMask & kCGImageAlphaPremultipliedLast);
    CGContextClipToMask(bitmapContext, bounds, maskImage);
    CGContextSetFillColorWithColor(bitmapContext, color.CGColor);
    CGContextFillRect(bitmapContext, bounds);
    CGImageRef cImage = CGBitmapContextCreateImage(bitmapContext);
    UIImage *coloredImage = [UIImage imageWithCGImage:cImage scale:self.scale orientation:self.imageOrientation];
    return coloredImage;

function recurseCopy($src, $dst, $excludeFileType=array()) {
    $dir = opendir($src);
    mkdir($dst, 0755, true);
    while(false !== ( $file = readdir($dir)) ) {

                    copy($src . '/' . $file, $dst . '/' . $file);
