在 react-native-router-flux 中使用 Actions.reset("key") 时,会对组件产生什么影响
when using Actions.reset("key") in react-native-router-flux, what will affect the component
我使用 react-native-router-flux 作为 react-native 路由器,在我的情况下,当用户登出时,我使用 Action.reset("key"),但是 getDerivedStateFromProps
next props
还有pre-data,谁能告诉我原因,或者如何用其他方式解决问题。
react-native-router-flux 基于 react-navigaion。这样我们就可以找到概念和解释。
首先我们看到js源代码,它位于navigationStore
reset = (routeName, data) => {
const params = filterParam(data);
const parent = getParent(this.state, routeName);
this.dispatch(
StackActions.reset({
index: 0,
key: parent ? parent.key : null,
actions: [
NavigationActions.navigate({
routeName,
params,
}),
],
}),
);
};
}
StackActions.reset
仅重置操作会擦除整个导航状态并将其替换为多个操作的结果。所以它只会改变导航状态。我们可以在 react-navigation api.
中看到
对于导航生命周期,与网络不同,导航不会重新安装组件。它管理路由器使用堆栈。以下为官方说法:
Consider a stack navigator with screens A and B. After navigating to A, its componentDidMount is called. When pushing B, its componentDidMount is also called, but A remains mounted on the stack and its componentWillUnmount is therefore not called.
When going back from B to A, componentWillUnmount of B is called, but componentDidMount of A is not because A remained mounted the whole time.
因此,当组件从路由器堆栈中移除时,导航将卸载该组件,例如返回、重置
