React Native CLI项目中的箭头函数逻辑

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

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      count: 0
    };
  }

  componentDidMount() {
    // 组件挂载后执行的逻辑
  }

  handleClick = () => {
    this.setState(prevState => ({
      count: prevState.count + 1
    }));
  }

  render() {
    return (
      <View>
        <Text>{this.state.count}</Text>
        <TouchableOpacity onPress={this.handleClick}>
          <Text>点击增加</Text>
        </TouchableOpacity>
      </View>
    );
  }
}

export default MyComponent;
