UIImage图片换颜色

有时候我们需要同一张图片在不同情况下显示不同的颜色，让UI出图费时费力，自己出图自己又懒(别和我比懒，我懒得和你比)，所以还是用代码解决吧😊
Swift版

//MARK: 改变图片颜色
extension UIImage{
    /// 更改图片颜色
    public func maskImageWithColor(color : UIColor) -> UIImage{
        UIGraphicsBeginImageContext(self.size)
        color.setFill()
        let bounds = CGRect.init(x: 0, y: 0, width: self.size.width, height: self.size.height)
        UIRectFill(bounds)
        self.draw(in: bounds, blendMode: CGBlendMode.destinationIn, alpha: 1.0)
        let tintedImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return tintedImage!
    }
}

OC版

- (UIImage *) maskImageWithColor:(UIColor *)color
{
    NSParameterAssert(color != nil);
    
    CGRect imageRect = CGRectMake(0.0f, 0.0f, self.size.width, self.size.height);
    UIImage *newImage = nil;
    
    UIGraphicsBeginImageContextWithOptions(imageRect.size, NO, self.scale);
    {
        CGContextRef context = UIGraphicsGetCurrentContext();
        
        CGContextScaleCTM(context, 1.0f, -1.0f);
        CGContextTranslateCTM(context, 0.0f, -(imageRect.size.height));
        
        CGContextClipToMask(context, imageRect, self.CGImage);
        CGContextSetFillColorWithColor(context, color.CGColor);
        CGContextFillRect(context, imageRect);
        
        newImage = UIGraphicsGetImageFromCurrentImageContext();
    }
    UIGraphicsEndImageContext();
    
    return newImage;
}
