Taro: 请问要怎么样才能使组件的 componentDidShow 起作用啊？

[jswxwxf]

原来以为 1.2.0 里可以，但是发现还是不行。只有页面的 componentDidShow 可以工作。

暂时将状态从页面传下去吧

[AvailCat]

@luckyadam @jswxwxf @tourze 在微信官方社区看到 组件嵌套时pageLifetimes中的show不会被触发 的反馈，Taro 的页面也是用了 Component 构造器 而不是 Page 构造器，似乎是会触发这个问题的

https://github.com/NervJS/taro/blob/cfb49092fa0bde2b62f97c3ffe845e262d571936/packages/taro-cli/src/weapp.js#L765-L769

BTW: 询问了微信的朋友说这个 Bug 已经安排处理了

@Meeeeow 大赞~

[Chen-jj]

@jswxwxf CLI 、依赖、开发者工具都升级到最新版本后应该能正常触发了。
