RN-Clipboard:复制文字到系统粘贴板上

yarn add @react-native-clipboard/clipboard

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

import Clipboard from '@react-native-community/clipboard'



class AwesomeProject extends Component {
    state = {
        content: 'Content will appear here'
    };
    //异步函数 箭头函数不需要绑定this了
    _setClipboardContent = async () => {

        // 将文字复制到系统的粘贴板上，在系统其他的地方可以粘贴
        Clipboard.setString('Hello World');


       // 取出所存的值， Clipboard.getString()  返回的是以一个promise对象，所以可以在then里面存到state，或者使用同步存到state中
        try {
            var content = await Clipboard.getString();
            this.setState({content});
        } catch (e) {
            this.setState({content:e.message});
        }
    };

    render() {
        return (
            <View>
                <Text onPress={this._setClipboardContent}
                      style={{color: 'blue',marginTop:100}}>
                    Tap to put "Hello World" in the clipboard
                </Text>
                <Text style={{color: 'red', marginTop: 20}}>
                    {this.state.content}
