Question

在我的抽屉式导航器中，当我按注销时，有一个注销按钮。我想删除app_token，但不知道如何。

我试着放这样的东西：

onItemPress:() => { AsyncStorage.removeItem('app_token')},

但这没用。

const AppDrawerNavigator = createDrawerNavigator({



      Logout: {

    onItemPress:() => { AsyncStorage.removeItem('app_token')},

          screen: HomePage,
          navigationOptions: {


              drawerIcon: (
                  <Image style={{ width: 30, height: 30 }}
                         source={require('./assets/IconDrawerNavigation/logout.png')} />
              )
          }
      },

} ）;

为解决此问题，我使用了一个名为contentComponent的道具，您可以创建自己的抽屉

import drawerContentComponents from './Drawer';

const AppDrawerNavigator = createDrawerNavigator({

  Home: {screen: Home,}
  },

},
  {contentComponent: drawerContentComponents,}

  );

//抽屉源代码

//i use this library so i can restart the app and logout 
import RNRestart from 'react-native-restart'; 

export default class drawerContentComponents extends Component {


    _logout = () => {
        AsyncStorage.removeItem('sale_id');
        RNRestart.Restart();

    }
    render() {


        return (

            <View style={styles.container2}>

                <TouchableOpacity onPress={() => this.props.navigation.navigate('profile')} >
                    <View style={styles.screenStyle}>
                        <Image style={styles.iconStyle}
                            source={home} />
                        <Text style={styles.screenTextStyle}>My Profile</Text>
                    </View>
                    <View style={styles.underlineStyle} />
                </TouchableOpacity>


                <TouchableOpacity onPress={() => this.props.navigation.navigate('social')} >
                    <View style={styles.screenStyle}>
                        <Image style={styles.iconStyle}
                            source={home} />
                        <Text style={styles.screenTextStyle}>Contact US</Text>
                    </View>
                    <View style={styles.underlineStyle} />
                </TouchableOpacity>



                <TouchableOpacity onPress={this._logout} >
                    <View style={styles.screenStyle}>
                        <Image style={styles.iconStyle}
                            source={home} />
                        <Text style={styles.screenTextStyle}>Logout</Text>
                    </View>

                </TouchableOpacity>


            </View>

        )
    }
}
