微信小程序：关注公众号组件自定义样式

概要

关注微信公众号组件，官方提供了official-account，只有在固定的场景下才会显示，比如扫码进入的小程序才会显示。更多相关场景：开发能力/official-account。

公众号组件official-account，本身样式是固定的，也不支持修改样式。但是在做微信小程序的时候，有个需求就是把关注公众号的组件改成一个按钮，不要问为什么，因为有现成的别人家的小程序就可以点击一个按钮去关注公众号。于是在网上搜了一些案例，发现没一个靠谱的。不过后来，被我攻破了这个难关。那么我就把这个关注公众号组件自定义样式方法分享出来。

下面的实现案例，使用了uniapp打包，仅做参考。如需在原生微信小程序中使用，则需要读懂代码，在此基础上依葫芦画瓢。

Tips

此案例可以直接当成一个组件使用，需要改样式及文字，可以自行修改，这里展示的仅做参考，最重要的是思路。isFollow表示是否关注过公众号，我处理的思路是通过后端接口判断是否关注过公众号，关注过就不显示该组件了，仅做参考。max 表示最多点几次关闭按钮，就不再显示该组件了，仅做参考。主要思路：先让组件显示，但是透明度为0=》然后判断组件的宽高，有宽高说明该场景可以显示公众号组件=》通过是否关注过公众号，判断是否显示=》最终的目的就是显示自己定义的按钮，在按钮上面其实是覆盖了公众号组件，位置刚好调整在关注的按钮上面，透明度为0，所以看到的就是自己的按钮，点击的其实还是组件上的按钮。
