react-native-orientation-director

A React Native library that allows you to listen to orientation changes, lock interface orientation
to a selected one and get current orientation.
Written in Kotlin, Swift and Typescript. It supports both the Old and New React Native architecture.

This library takes inspiration from and builds upon the following amazing alternatives:

1. react-native-orientation-locker
2. react-native-orientation-handler

Features

- [x] Get the current orientation of the device
- [x] Get the current orientation of the interface
- [x] Get the current interface orientation status (locked or unlocked)
- [x] Listen to device orientation changes
- [x] Listen to interface orientation changes
- [x] Listen to interface orientation status changes
- [x] Lock the interface orientation to a specific orientation
- [x] Unlock the interface orientation
- [x] Reset supported interface orientations to settings
- [x] Check if autorotation is enabled (Android only)

Installation

$3

You can install the package via npm or yarn:

``sh
npm install react-native-orientation-director
`

`sh
yarn add react-native-orientation-director
`

Don't forget to run pod-install.

$3

You can install the package like any other Expo package, using the following command:

`sh
npx expo install react-native-orientation-director
`

Setup

$3

Simply add the library plugin to your app.json file:

`json
{
"expo": {
"plugins": [
"react-native-orientation-director"
]
}
}
`

This way, Expo will handle the native setup for you during prebuild.

> Note: only SDK 50 and above are supported, the plugin is configured to handle only the kotlin template.

#### Android

This library uses a custom broadcast receiver to handle the manual orientation changes: when the user disables the
autorotation feature and the system prompts the user to rotate the device, the library will listen to the broadcast
sent by the MainActivity and update the interface orientation accordingly.

To allow the library to listen to the broadcast, you need to override the onConfigurationChanged method in MainActivity.kt as shown below:

`kotlin
// ...

import android.content.Intent
import android.content.res.Configuration
import com.orientationdirector.implementation.ConfigurationChangedBroadcastReceiver

class MainActivity : ReactActivity() {

// ...

override fun onConfigurationChanged(newConfig: Configuration) {
super.onConfigurationChanged(newConfig)

val orientationDirectorCustomAction =
"${packageName}.${ConfigurationChangedBroadcastReceiver.CUSTOM_INTENT_ACTION}"

val intent =
Intent(orientationDirectorCustomAction).apply {
putExtra("newConfig", newConfig)
setPackage(packageName)
}

this.sendBroadcast(intent)
}
}
`

Nothing else is required for Android.

#### iOS

To properly handle interface orientation changes in iOS, you need to update your AppDelegate file. Since React Native
0.77, the AppDelegate has been migrated to Swift, so see the instructions below for both Swift and Objective-C.

##### Objective-C

In your AppDelegate.mm file, import "OrientationDirector.h" and implement supportedInterfaceOrientationsForWindow method as follows:

`objc
#import

- (UIInterfaceOrientationMask)application:(UIApplication )application supportedInterfaceOrientationsForWindow:(UIWindow )window
{
return [OrientationDirector getSupportedInterfaceOrientationsForWindow];
}
`

##### Swift

You need to create a bridging header
to import the library, as shown below:

`
#import "OrientationDirector.h"
`

Then, in your AppDelegate.swift file, implement the supportedInterfaceOrientationsFor method as follows:

`swift
override func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
return OrientationDirector.getSupportedInterfaceOrientationsForWindow()
}
`

Note: if you are targeting react-native > 79.x, you can omit the override` keyword.

If you need help, you can check the example project.

Usage

This library exports a class called: RNOrientationDirector that exposes the following methods:

| Method | Description |
|------------------------------------------|-----------------------------------------------------------------------------------|
| getInterfaceOrientation | Returns the last interface orientation |
| getDeviceOrientation | Returns the last device orientation |
| lockTo | Locks the interface to a specific orientation |
| unlock | Unlock the interface |
| isLocked | Returns the current interface orientation status (locked / unlocked) |
| isAutoRotationEnabled | (Android Only) Returns if auto rotation is enabled |
| listenForDeviceOrientationChanges | Triggers a provided callback each time the device orientation changes |
| listenForInterfaceOrientationChanges | Triggers a provided callback each time the interface orientation changes |
| listenForLockChanges | Triggers a provided callback each time the interface orientation status changes |
| convertOrientationToHumanReadableString | Returns a human readable string based on the given orientation |
| convertAutoRotationToHumanReadableString | Returns a human readable string based on the given auto rotation |
| setHumanReadableOrientations | Sets the mapping needed to convert orientation values to human readable strings |
| setHumanReadableAutoRotations | Sets the mapping needed to convert auto rotation values to human readable strings |
| resetSupportedInterfaceOrientations | Resets the supported interface orientations to settings |
| isLockableOrientation | Determines if orientation is lockable |

In addition, the library exposes the following hooks:

| Hook | Description |
|-----------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------|
| useInterfaceOrientation | Returns the current interface orientation and listens to changes |
| useDeviceOrientation | Returns the current device orientation and listens to changes |
| useIsInterfaceOrientationLocked | Returns the current interface orientation status and listens to changes |

Head over to the example project to see how to use the library.

Please be aware that there is a subtle difference between the device orientation
and the interface orientation.

When you device is either in landscape left or right orientation, your interface
is inverted, this is why lockTo method needs a second parameter to discriminate
which type of orientation your are supplying.

To match developers expectations, if you supply a device orientation and
OrientationType.device, lockTo switches landscapeRight with left and vice versa
to property align the interface orientation.

This behavior comes from the native API, you can find more information in their
documentation:

1. iOS - UIInterfaceOrientation
2. iOS - UIDeviceOrientation
3. Android - getRotation>)

$3

Since on Android we need to deal with sensors and their usage, it is worth noting that the device orientation computation works
differently than on iOS, mainly in the following ways:

1. Upon start up, all required sensors are enabled just for the initial device orientation computation, then they are disabled;
2. Each time a new device orientation listener is added, all required sensors are enabled if disabled;
3. After the last device orientation listener is removed, all required sensors are disabled;

This behavior allows us to follow Google's best practices related to the Sensors Framework. More here.

Roadmap

- [ ] Add JS side tests
- [ ] Add iOS side tests
