javascript - 动态 react 抽屉导航锁

Question

如何动态锁定抽屉？我有来自 react-native-modalbox 的模式使用。当我打开模式时，我调用 this.refs.modal.open(); 并锁定抽屉。我只知道drawerLockMode可以在navigationOptions中设置。但模态并不是 DrawerNavigator

中的屏幕

const MainDrawer = DrawerNavigator({
    Event: { screen: EventScreen },
    Wallet: { screen: WalletScreen},
    Profile: { screen: ProfileScreen},
    Contact: { screen: MemberContactScreen},
    Reward: { 
      screen: MemberRewardScreen,
      navigationOptions:{
        drawerLockMode :'locked-closed'
      }},
},{
  contentComponent: props => <DrawerScreen {...props} />
});

我使用了以下代码

    static navigationOptions = ({ navigation }) => ({
drawerLockMode: navigation.state.params ? navigation.state.params.drawerLockMode : undefined});

为了隐藏抽屉导航，在称为此的条件下使用了此代码。

    this.props.navigation.setParams({ 
    drawerLockMode: locked-closed });
