我有2个组件A,B如下所示,

class A extends Component {

  testMethodA() {

  }

  render() {
      return (
          <View style={[styles.scene, {backgroundColor: 'red'}]}>
              <TouchableHighlight onPress={this.onPress}>
                  <Text>Welcome. Press here!</Text>
              </TouchableHighlight>
          </View>
      );
  }
}


class B extends Component {

  testMethodB() {

  }

  render() {
      return (
          <View style={[styles.scene, {backgroundColor: 'red'}]}>
              <TouchableHighlight onPress={this.onPress}>
                  <Text>Welcome. Press here!</Text>
              </TouchableHighlight>
          </View>
      );
  }
}

如何访问testMethodA从B和testMethodB从A？
