Using CocoaPods (iOS Only)

pod 'react-native-orientation', :path => 'node_modules/react-native-orientation'

Consult the React Native documentation on how to install React Native using CocoaPods.

Manually

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

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)

   import com.github.yamill.orientation.OrientationPackage;  // <--- import
   
   public class MainApplication extends Application implements ReactApplication {
     ......
   
     @Override
     protected List<ReactPackage> getPackages() {
         return Arrays.<ReactPackage>asList(
             new MainReactPackage(),
             new OrientationPackage()      <------- Add this
         );
     }
   
     ......
   
   }
   

Configuration

iOS

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

#import "Orientation.h" // <--- import

@implementation AppDelegate

  // ...

  - (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return [Orientation getOrientation];
  }

@end

Usage

Whenever you want to use it within React Native code now you can: var Orientation = require('react-native-orientation');

  _orientationDidChange: function(orientation) {
    if (orientation == 'LANDSCAPE') {
      //do something with landscape layout
    } else {
      //do something with portrait layout
    }
  },

  componentWillMount: function() {
    //The getOrientation method is async. It happens sometimes that
    //you need the orientation at the moment the js starts running on device.
    //getInitialOrientation returns directly because its a constant set at the
    //beginning of the js code.
    var initial = Orientation.getInitialOrientation();
    if (initial === 'PORTRAIT') {
      //do stuff
    } else {
      //do other stuff
    }
  },

  componentDidMount: function() {
    Orientation.lockToPortrait(); //this will lock the view to Portrait
    //Orientation.lockToLandscape(); //this will lock the view to Landscape
    //Orientation.unlockAllOrientations(); //this will unlock the view to all Orientations

    Orientation.addOrientationListener(this._orientationDidChange);
  },

  componentWillUnmount: function() {
    Orientation.getOrientation((err,orientation)=> {
      console.log("Current Device Orientation: ", orientation);
    });
    Orientation.removeOrientationListener(this._orientationDidChange);
  }

Events

• addOrientationListener(function(orientation))

orientation can return either LANDSCAPE PORTRAIT UNKNOWN also PORTRAITUPSIDEDOWN is now different from PORTRAIT

• removeOrientationListener(function(orientation))

• addSpecificOrientationListener(function(specificOrientation))

specificOrientation can return either LANDSCAPE-LEFT LANDSCAPE-RIGHT PORTRAIT UNKNOWN PORTRAITUPSIDEDOWN

• removeSpecificOrientationListener(function(specificOrientation))

Functions

• lockToPortrait()
• lockToLandscape()
• lockToLandscapeLeft()
• lockToLandscapeRight()
• unlockAllOrientations()
• getOrientation(function(err, orientation)

orientation can return either LANDSCAPE PORTRAIT UNKNOWN PORTRAITUPSIDEDOWN

• getSpecificOrientation(function(err, specificOrientation)

specificOrientation can return either LANDSCAPE-LEFT LANDSCAPE-RIGHT PORTRAIT UNKNOWN PORTRAITUPSIDEDOWN

TODOS

• Add some way to allow setting a preferred orientation on a screen by screen basis.
• Make API Cleaner to Orientation Locking
• Android Support
