ES6下子组件调用父组件的方法(推荐)

export default class TestPrj extends Component {    constructor(props){      super(props);      this.timesReset = this.timesReset.bind(this);      this.state = {timex:2};    }    timesReset(){      this.setState({        timex:0      });    }    render() {      return(        <View style={styles.container}>          <Son ref="Son1" timex={this.state.timex} timesReset={this.timesReset}/>          //或者<Son ref="Son1" timex={this.state.timex} timesReset={this.timesReset.bind(this)}/>        </View>      );    }  } class Son extends Component{    constructor(props){    super(props);    this.state = {times:this.props.timex};  }  componentWillReceiveProps(props){    console.log(this.props);    this.setState({      times:props.timex    })  }  timesReset(){    this.props.timesReset();  }  render(){    return(    <View style={styles.container}>      <Text style={styles.instructions}>      儿子：虽然你揍了我 {this.state.times} 次，但是我 永 不 屈 服！！      </Text>      <TouchableHighlight style={styles.btn} underlayColor={'pink'} onPress={this.timesReset.bind(this)}>        <Text style={{textAlign:'center'}}>爹，再给你儿子一次机会！！</Text>      </TouchableHighlight>    </View>    );  }}
