React Native Orientation

Listen to device orientation changes in React Native applications and programmatically set preferred orientation on a per screen basis. Works on both Android and iOS.

Installing

npm install react-native-orientation --save

Linking Native Dependencies

Automatic Linking

react-native link react-native-orientation

Please note that you still need to manually configure a couple files even when using automatic linking. Please see the 'Configuration' section below. You will also need to restart your simulator before the package will work properly.

Manual Linking

iOS

1. Add node_modules/react-native-orientation/iOS/RCTOrientation.xcodeproj to your xcode project, usually under the Libraries group
2. Add libRCTOrientation.a (from Products under RCTOrientation.xcodeproj) to build target's Linked Frameworks and Libraries list
3. Add $(SRCROOT)/node_modules/react-native-orientation/iOS/RCTOrientation/ to Project Name -> Build Settings -> Header Search Paths

Android

1. In android/setting.gradle

   ...
   include ':react-native-orientation', ':app'
   project(':react-native-orientation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-orientation/android')
   

2. In android/app/build.gradle

   ...
   dependencies {
   ...
   compile project(':react-native-orientation')
   }
   

3. Register module in MainApplication.java

   importcom.github.yamill.orientation.OrientationPackage; // <--- importpublicclassMainApplicationextendsApplicationimplementsReactApplication {
   ......
   @OverrideprotectedList<ReactPackage> getPackages() {
   returnArrays.<ReactPackage>asList(
   newMainReactPackage(),
   newOrientationPackage() <------- Addthis
   );
   }
   ......
   }

Configuration

iOS

Add the following to your project's AppDelegate.m:

#import"Orientation.h"// <--- import@implementationAppDelegate// ...
- (UIInterfaceOrientationMask)application:(UIApplication *)applicationsupportedInterfaceOrientationsForWindow:(UIWindow *)window {
return [Orientation getOrientation];
}
@end

Android

Implement onConfigurationChanged method in MainActivity.java

importandroid.content.Intent; // <--- importimportandroid.content.res.Configuration; // <--- importpublicclassMainActivityextendsReactActivity {
......
@OverridepublicvoidonConfigurationChanged(ConfigurationnewConfig) {
super.onConfigurationChanged(newConfig);
Intentintent = newIntent("onConfigurationChanged");
intent.putExtra("newConfig", newConfig);
this.sendBroadcast(intent);
}
......
}

Usage

To use the react-native-orientation package in your codebase, you should use the Orientation module:

importOrientationfrom'react-native-orientation';

exportdefaultclassAppScreenextendsComponent{// ...componentWillMount(){// The getOrientation method is async. It happens sometimes that// you need the orientation at the moment the JS runtime starts running on device.// `getInitialOrientation` returns directly because its a constant set at the// beginning of the JS runtime.constinitial=Orientation.getInitialOrientation();if(initial==='PORTRAIT'){// do something}else{// do something else}},componentDidMount(){// this locks the view to Portrait ModeOrientation.lockToPortrait();// this locks the view to Landscape Mode// Orientation.lockToLandscape();// this unlocks any previous locks to all Orientations// Orientation.unlockAllOrientations();Orientation.addOrientationListener(this._orientationDidChange);},_orientationDidChange=(orientation)=>{if(orientation==='LANDSCAPE'){// do something with landscape layout}else{// do something with portrait layout}},componentWillUnmount(){Orientation.getOrientation((err,orientation)=>{console.log(`Current Device Orientation: ${orientation}`);});// Remember to remove listenerOrientation.removeOrientationListener(this._orientationDidChange);}render(){// ...return(// ...)}}

Orientation Events

addOrientationListener((orientation)=>{});

orientation will return one of the following values:

• LANDSCAPE
• PORTRAIT
• PORTRAITUPSIDEDOWN
• UNKNOWN

removeOrientationListener((orientation)=>{});

addSpecificOrientationListener((specificOrientation)=>{});

specificOrientation will return one of the following values:

• LANDSCAPE-LEFT
• LANDSCAPE-RIGHT
• PORTRAIT
• PORTRAITUPSIDEDOWN
• UNKNOWN

removeSpecificOrientationListener((specificOrientation)=>{});

API

• lockToPortrait()
• lockToLandscape()
• lockToLandscapeLeft()
• lockToLandscapeRight()
• unlockAllOrientations()
• getOrientation((err, orientation) => {})
• getSpecificOrientation((err, specificOrientation) => {})
