@react-native-segmented-control/segmented-control

React Native SegmentedControl library. Use SegmentedControl to render a UISegmentedControl iOS.

For Android and Web, it has a js implementation that mocks iOS 13 style of UISegmentedControl.

iOS	Android	Web

Supported React Native Version

react-native-segmented-control	react-native
v2.2.0	>= 0.62
<= v2.2.0	>= 0.57

This module is NOT supported in the Expo Go app on iOS, because it requires custom native code. You need to use a custom development client or eject into bare workflow in order to use this module on iOS.

Getting started

Install the library using your package manager:

pnpm:

pnpm install --save @react-native-segmented-control/segmented-control

yarn:

yarn add @react-native-segmented-control/segmented-control

npm:

npm install --save @react-native-segmented-control/segmented-control

Link

React Native 0.60+

The package is automatically linked when building the app. All you need to do is:

npx pod-install

For android, no linking is needed, as the module is implemented in js.

For React Native version 0.59 or older

### React Native <= 0.59

run react-native link @react-native-segmented-control/segmented-control

or you can follow the instructions to manually link this package.

Upgrading to React Native 0.60+

New React Native comes with autolinking feature, which automatically links Native Modules in your project. In order to get it to work, make sure you unlink Segmented Control first:

react-native unlink @react-native-segmented-control/segmented-control

Migrating from the core react-native module

This module was created when the segmentedControlIos was split out from the core of React Native. To migrate to this module you need to follow the installation instructions above and then change you imports from:

import {SegmentedControlIOS} from 'react-native';

to:

import SegmentedControl from '@react-native-segmented-control/segmented-control';

Usage

Start by importing the library:

Use SegmentedControl 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.

import SegmentedControl from '@react-native-segmented-control/segmented-control';

return (
   {
      this.setState({selectedIndex: event.nativeEvent.selectedSegmentIndex});
    }}
  />
);

Tips and Tricks

How can I increase the height of the tab ?

For android and IOS, simply pass prop.style:

{
  "height": number
}

For react-native-web, additionally pass :

{
  "paddingVertical": number,
  or
  "height": number
}

Adding padding makes text disappear on Android

If padding amount exceeds the fixed height of the container, it will shrink the text. So either increase the height or reduce your padding.
