react-navigation：如何在多个屏幕中包装navigationOptions

Question

我只是想知道是否必须在所有屏幕上放置navigationOptions 。 像这样：

const AppStackNavigator = createStackNavigator({
  welcome: {
  screen: WelcomeScreen,
  navigationOptions: {
      header: null
    },
  },
  email: {
  screen: EmailLoginScreen,
  navigationOptions: {
      header: null
    },
  },
  password: {
  screen: FindPassWordScreen,
  navigationOptions: {
      header: null
    },
  },
  register: {
  screen: RegisterScreen,
  navigationOptions: {
      header: null
    },
  },
  agree: {
  screen: AgreementScreen,
  navigationOptions: {
      header: null
    }
  }
  })

我可以将navigationOptions包装到所有屏幕吗？ 但是，这将使我出错。

const AppStackNavigator = createStackNavigator({
  welcome: WelcomeScreen,
  email:EmailLoginScreen,
  password:FindPassWordScreen,
  register: RegisterScreen,
  agree: AgreementScreen,
  navigationOptions: {
      header: null
    },
})

是的，可以将设置应用到所有路线，您做错了

这里，

const AppStackNavigator = createStackNavigator({
  welcome: WelcomeScreen,
  email:EmailLoginScreen,
  password:FindPassWordScreen,
  register: RegisterScreen,
  agree: AgreementScreen,
},{
    navigationOptions: {
      header: null
    }
})
