是否可以重新加载顶级React Native组件以刷新所有子组件？

Question

I'm working on an iPad app that needs to reset itself at midnight each night. Most of the children components contain data that needs to be wiped or refreshed for the new day. Is it possible to reload (forceUpdate() didn't do the trick) the whole app programmatically?

I realize it's counter to the React paradigm, but seems overly complicated to change some dummy state in all the children to reset them!

Thanks!

forceUpdate（）是一个生命周期函数，但是除非没有办法，否则最好不要使用它来更新子组件，而应使用setState来更新子组件。
