背景

随着公司业务的发展，现在的产品真的是越来越体(sang)贴(xin)用(bing)户(kuang) 了，刚好前阵子准备做一个后台可以让用用户 DIY 自己的小程序，不小心看到了某网提供了一套图标库，用户可以自主选择，并且可以进行颜色配置的时候，我就感觉事情不妙~

当时脑子一热，桌子一拍，我们也需要提供这样的功能，而且要做的比他们还强大...

作为开发的我默默的留下了这张图~

我们知道小程序里面是不支持类似 ttf woff 这类字体的，直接引入编译都过不去~

这个就是要告诉我们，我们不能像 H5 那样直接把字体下载下来然后引入到样式中，这条道路是行不通了，只能重新找找方案了~

嗯，我也不藏着掖着了，接下来给大家安利 2 中解决方案~

解决方案

方案一

利用小程序中不支持 ttf 字体，却支持 base64 的特点，我们可以通过将 ttf 字体转码成 base64 ，再通过 iconfont 的特点，通过设置字体大小和颜色来达到目的。

其具体实现如下：

1.我们可以先去阿里提供的图标库官网下载我们需要的图标，一般来说都够用了，这里我随便好了 3 个作为测试用，点击 下载代码 将代码下载到本地~

2.解压我们刚才下载的包，会有以下这些文件，但对于我们来说，会用到的只有 iconfont.css 和 iconfont.ttf 这两个文件，

3.我们要对 iconfont.ttf 这个文件进行转码，将它转成 base64 格式，刚好这个网站就提供了这个功能（pass：这个网站可能会有点慢，可以的话代理加个速），按照下图的步骤，分别上传 ttf 文件，选择配置，点击转换。

4.转换完成如下图所示，废话不多说，直接下载下来解压，我们需要的是里面 stylesheet.css 这个文件

5.我们在小程序里的静态资源文件夹里新建一个叫 iconfont.wxss 样式文件，将上面解压出来的 stylesheet.css 里面的内容全部拷贝到 iconfont.wxss 中，另外，还记得我们上面说的 iconfont.css 吗？这时候就要派上用场了，我们打开 iconfont.css 这个样式文件，将下面的样式，也就是我用红框标注的内容复制到 iconfont.wxss 文件里，注意上面的不需要复制！！

到此为止，准备工作算是已经完成了，这时候你的 iconfont.wxss 应该类似下面这样

iconfont.wxss

    font-weight: normal;
    font-style: normal;
}

.iconfont {
  font-family:"iconfont" !important;
  font-size:16px;
  font-style:normal;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
}

.icon-map:before { content: "\e6a2"; }

.icon-success:before { content: "\e6b3"; }

.icon-atm:before { content: "\e6bd"; }

6.接着，将我们的字体文件引入到 app.wxss 全局 , 这样你就可以在任何你想用到的地方进行调用了，只需要将 class 写对就没什么问题了，

<!--index.wxml-->
<view class="container">
    <view class='block'>
        <text class='iconfont icon-map'></text>
        <text>地图</text>
    </view>
    <view class='block'>
        <text class='iconfont icon-success'></text>
        <text>成功</text>
    </view>
    <view class='block'>
        <text class='iconfont icon-atm'></text>
        <text>atm</text>
    </view>
</view>

怎么样，成功了吧！

什么？你要换颜色，难不倒我的，只要改变对应的 color 就可以了~

<!--index.wxml-->
<view class="container">
    <view class='block'>
        <text class='iconfont icon-map' style='color : red'></text>
        <text>地图</text>
    </view>
    <view class='block'>
        <text class='iconfont icon-success' style='color : green'></text>
        <text>成功</text>
    </view>
    <view class='block'>
        <text class='iconfont icon-atm' style='color : blue'></text>
        <text>atm</text>
    </view>
</view>

嗯，是不是可以插会儿腰了~

且慢，刚不是说两种方案么，怎么到这里就叉起腰来了，还没完呢，等会嘚瑟哈！！

方案二

刚介绍了方案一，确实是一种选择，我们只需约定好样式，类名，后端将颜色什么的返回给我们就好了~

但是这种方案存在弊端，不够灵活，如果我们要更新我们的图标库，那么我们上面的流程又得走一遍，如果后面图标库的类型变多，那么我们转码后的文件会随之变大，这对于小程序来说是致命的，因为做小程序都知道，我们都在时刻想着如何用最少的代码发挥最大的价值！

所以，这种方案有一定的局限性，因此才出了第二套方案~

第二套方案的思路是借助 svg 矢量图具有不失真和可以自主填充颜色的特点，通过 fill 属性，用户可以自定义填充颜色，但是小程序里面不支持 svg 标签的，我们通过颜色选择器将用户选择好的颜色填充到 svg 里，在通过转码将换过颜色的 svg 转成 base64 编码发给小程序，小程序可以直接用在 image 标签中的 src 属性上~

我们一起来试试~

1.我们还是先去阿里提供的图标库官网下载我们需要的图标，这次跟第一次有些不一样，这次我们要选择下载素材，选择 svg~

2.将下载好的 svg 源代码直接放在我们的图标库里面，选择某个图标之后，通过颜色选择器我们可以通过 js 设置对应的 svg 图标的 fill 属性，动态的给图标填充不同的颜色，差不多就跟下面的效果有点相似~

3.接下来可以将换过颜色的 svg 通过 svg 转 base64 的插件将其转换成 base64 编码，这里为了方便，我直接偷懒，在线转换了，对应的 base64 编码如下：

4.接着我们只需要把对应的 base64 编码发给小程序端，小程序直接放在 image 组件中的 src 属性即可，对于样式来说，可以直接修改 image 的样式来控制 icon 样式，效果如下：

ok~ 还算是比较圆满的完成了任务~

这下产品总不会刁难我了吧~

结语

到此，我们已经 get 到了两种小程序中实现 icon 自定义颜色的解决方案，对比发现，第一种方案的特点是实现起来比较简单，步骤什么的也都还ok，就是拓展性不强，每次改动都需要重新再来一遍，而且对于比较多的图标来说小程序空间占用较大，有一定的局限性，而第二种方案相比于第一种来说虽然在实现过程中稍微繁琐了一些，但是带来的效果是显而易见的，解决了第一种方案的弊端，拓展性什么的都很好，是我比较推荐的，也是我们正在采用的一种方案~

当然，这不过是我的一种实现思路，如果你有关于这方面更好的解决方案记得及时艾特我，我已经迫不及待的等待学习了~
