利用数码测色计来获取需求原型图中的颜色，设置为开发中的颜色

    CGFloat R  = (CGFloat) 225/255.0;
    CGFloat G = (CGFloat) 66/255.0;
    CGFloat B = (CGFloat) 88/255.0;
    CGFloat alpha = (CGFloat) 1.0;
    
    UIColor *myColorRGB = [ UIColor colorWithRed: R  green: G  blue: B  alpha: alpha  ];
    
    cell.iconImageView.backgroundColor = myColorRGB;
