Use SegmentedControlIOS to render a UISegmentedControl iOS.

Programmatically changing selected index

The selected index can be changed on the fly by assigning the selectedIndex prop to a state variable, then changing that variable. Note that the state variable would need to be updated as the user selects a value and changes the index, as shown in the example below.

<SegmentedControlIOS
  values={['One', 'Two']}
  selectedIndex={this.state.selectedIndex}
  onChange={(event) => {
    this.setState({selectedIndex: event.nativeEvent.selectedSegmentIndex});
  }}
/>
