title: Accessing method of another component on React-Native
body: <p>I have 2 components <code>A</code> and <code>B</code> as below,</p>
  
  <pre><code>class A extends Component {
  
    testMethodA() {
  
    }
  
    render() {
        return (
            &lt;View style={[styles.scene, {backgroundColor: 'red'}]}&gt;
                &lt;TouchableHighlight onPress={this.onPress}&gt;
                    &lt;Text&gt;Welcome. Press here!&lt;/Text&gt;
                &lt;/TouchableHighlight&gt;
            &lt;/View&gt;
        );
    }
  }
  
  
  class B extends Component {
  
    testMethodB() {
  
    }
  
    render() {
        return (
            &lt;View style={[styles.scene, {backgroundColor: 'red'}]}&gt;
                &lt;TouchableHighlight onPress={this.onPress}&gt;
                    &lt;Text&gt;Welcome. Press here!&lt;/Text&gt;
                &lt;/TouchableHighlight&gt;
            &lt;/View&gt;
        );
    }
  }
  </code></pre>
  
  <p>How can I access <code>testMethodA</code> from <code>B</code> and <code>testMethodB</code> from <code>A</code>?</p>
