iOS更改图片颜色

- (UIImage*)imageChangeColor:(UIColor*)color image:(UIImage *)image{
    //获取画布
    UIGraphicsBeginImageContextWithOptions(image.size, NO, 0.0f);
    //画笔沾取颜色
    [color setFill];
    
    CGRect bounds = CGRectMake(0, 0, image.size.width, image.size.height);
    UIRectFill(bounds);
    //绘制一次
    [image drawInRect:bounds blendMode:kCGBlendModeOverlay alpha:1.0f];
    //再绘制一次
    [image drawInRect:bounds blendMode:kCGBlendModeDestinationIn alpha:1.0f];
    //获取图片
    UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
