iOS中使用blend改变图片颜色

这个属性很有意思自己可以看看,点击这里查看文章

下面是一个方法改变图片的颜色的方法

func drawImageColor(image: UIImage,color: UIColor) -> UIImage {        UIGraphicsBeginImageContextWithOptions(image.size, false, UIScreen.mainScreen().scale);    color.setFill();    let bounds = CGRectMake(0, 0, image.size.width, image.size.height);    UIRectFill(bounds);    image.drawInRect(bounds, blendMode: CGBlendMode.DestinationIn, alpha: 1);    let newImage = UIGraphicsGetImageFromCurrentImageContext();    UIGraphicsEndImageContext();        return newImage;}

接下来就自己看吧,自己琢磨了....
