reactjs – 无法在AsyncStorage中设置setItem

我无法使用AsyncStorage设置setItem.以下是我的代码.所以我从TextInput获取状态名称,然后将其存储在AsyncStorage onPress of TouchableOpacity中.我收到错误：

import React, { Component } from 'react';
import { View, Text, StyleSheet, TextInput, TouchableOpacity} from 'react-native';

class AsyncStorage extends Component {

    constructor(props) {
        super(props);
        this.state = {
            name:''
        }
        //this.asyncSetName = this.asyncSetName.bind(this)   //tried this too.
   };

    asyncSetName(){
        let name = this.state.name
        AsyncStorage.setItem('name', name);
    }

    render(){
        <View>
            <TextInput
                placeholder='Set Name here'
                onChangeText={(name) => this.setState({name})}
                value={this.state.name}
                autoCorrect={false}
            ></TextInput>

            <TouchableOpacity
                onPress={this.asyncSetName.bind(this)}
            >
                <Text>SetName</Text>
            </TouchableOpacity>
        </View>
    }
}

我究竟做错了什么？请帮忙.

您需要从react-native导入AsyncStorage

import { View, Text, StyleSheet, TextInput, TouchableOpacity , AsyncStorage} from 'react-native';

您还需要保持asyncSetName函数的绑定

取消注释这一行

this.asyncSetName = this.asyncSetName.bind(this)

同样由@Chris发现,您需要将您的类名更改为与AsyncStorage不同
