Question

index.js有这样的代码，它有StackNavigator

const App = StackNavigator({
  Home: {
    screen: Home,
  },
});

const AppNavigator = StackNavigator(
  {
    Login: {
      screen: SignIn,
    },
    SignUp: {
      screen: SignUp,
    },
    myApp: { screen: App },
  },
  {
    gestureEnabled: false,
    headerMode: 'none',
  },

);

我正在登录并推送到myApp路线，

this.props.navigation.dispatch(
      NavigationActions.reset({
        index: 0,
        key: null,
        actions: [NavigationActions.navigate({ routeName: 'myApp' })]
      })
    );

现在所有导航推送和流行goback工作我正在尝试切除那些无法正常工作。

从家里我想登录界面。我正在进行退出行动

logoutPressed() {

    const resetAction = NavigationActions.reset({
              index: 0,
              actions: [NavigationActions.navigate ({ routeName:  
              'Login' })],
     });

     this.props.navigation.dispatch(resetAction);

}

错误：routeName: 'Login' not found in StackNavigator是什么问题。如何解决。

Answer 1

您必须按如下方式编写堆栈导航器

 const App = StackNavigator({
      Home: {
        screen: Home,
      },
      Login: {
        screen: SignIn,
      },
  });

App StackNavigator没有登录路线，您需要在其导航中设置路线名称

反应导航重置动作不起作用
