Get name of button onPress in react native

Question

I have two buttons that both call the same onPress function. In the callback I want to be able to differentiate between which was pressed.

Answer 1

One solution is to pass that info as a parameter:

 this._toggle(event, 'A')}
/>

The callback would then use that parameter

_toggle(event, buttonId) {
  // Use buttonId
}

EDIT: Another solution is a parent component that always returns the title prop:

class RadioParent extends Component {
  render() {
    return (
       this.props.onPress(event, this.props.title)}
      />
    );
  }
}
