What is the best way to access the references of 'child controllers' in NavigatorIOS within a React Native app?

After diving into react-native for the past few days, I've encountered a dilemma regarding the NavigatorIOS component. Is there a way to access and manipulate 'child controllers' of NavigatorIOS similar to how it's done in native objective-c (with UINavigationController.viewControllers)? I'm looking to retrieve references and trigger some update methods.

_addNavigator: function (component, title) {

    var data = null;

    var temp = <NavigatorIOS
      style={{ flex: 1 }}
      barTintColor='#007AFF'
      titleTextColor="#fff"
      tintColor="#fff"
      translucent={false}
      initialRoute={{
        component: component,
        title: title,
        passProps: {
          data: data
        }
      }}/>;

    componentArray.push(temp);

    return temp;
  }

Answer №1

In NavigatorIOS, obtaining the reference of a child controller directly is not supported. However, we can leverage the EventEmitter library to achieve this functionality. EventEmitter functions in a similar manner to NSNotification. For further details, please refer to the following link: EventEmitter
