Installation

Using npm

npm install react-native-orientation-locker --save
react-native link react-native-orientation-locker

Using CocoaPods (iOS Only)

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

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

Configuration

iOS

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

+#import "Orientation.h"
 
@implementation AppDelegate
 
// ...
 
+- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
+  return [Orientation getOrientation];
+}
 
@end

Android

Add following to android/app/src/main/AndroidManifest.xml

      <activity
        ....
+       android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize">
 
          ....
 
      </activity>
 

Implement onConfigurationChanged method (in MainActivity.java)

// ...
 
+import android.content.Intent;
+import android.content.res.Configuration;
 
public class MainActivity extends ReactActivity {
 
+   @Override
+   public void onConfigurationChanged(Configuration newConfig) {
+       super.onConfigurationChanged(newConfig);
+       Intent intent = new Intent("onConfigurationChanged");
+       intent.putExtra("newConfig", newConfig);
+       this.sendBroadcast(intent);
+   }
 
    // ......
}

Usage

Whenever you want to use it within React Native code now you can: import Orientation from 'react-native-orientation-locker';

 
import Orientation from 'react-native-orientation-locker';
 
 
  _onOrientationDidChange = (orientation) => {
    if (orientation == 'LANDSCAPE-LEFT') {
      //do something with landscape left layout
    } else {
      //do something with portrait layout
    }
  };
 
  componentWillMount() {
    //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() {
 
    Orientation.getAutoRotateState((rotationLock) => this.setState({rotationLock}));
    //this allows to check if the system autolock is enabled or not.
 
    Orientation.lockToPortrait(); //this will lock the view to Portrait
    //Orientation.lockToLandscapeLeft(); //this will lock the view to Landscape
    //Orientation.unlockAllOrientations(); //this will unlock the view to all Orientations
 
    //get current UI orientation
    /*
    Orientation.getOrientation((orientation)=> {
      console.log("Current UI Orientation: ", orientation);
    });
 
    //get current device orientation
    Orientation.getDeviceOrientation((deviceOrientation)=> {
      console.log("Current Device Orientation: ", deviceOrientation);
    });
    */
 
    Orientation.addOrientationListener(this._onOrientationDidChange);
  },
 
  componentWillUnmount: function() {
    Orientation.removeOrientationListener(this._onOrientationDidChange);
  }

Events

• addOrientationListener(function(orientation))

When UI orientation changed, callback function will be called. But if lockToXXX is called , callback function will be not called untill unlockAllOrientations. It can return either PORTRAIT LANDSCAPE-LEFT LANDSCAPE-RIGHT PORTRAIT-UPSIDEDOWN UNKNOWN When lockToXXX/unlockAllOrientations, it will force resend UI orientation changed event.

• removeOrientationListener(function(orientation))

• addDeviceOrientationListener(function(deviceOrientation))

When device orientation changed, callback function will be called. When lockToXXX is called, callback function also can be called. It can return either PORTRAIT LANDSCAPE-LEFT LANDSCAPE-RIGHT PORTRAIT-UPSIDEDOWN UNKNOWN

• removeDeviceOrientationListener(function(deviceOrientation))

• addLockListener(function(orientation))

When call lockToXXX/unlockAllOrientations, callback function will be called. It can return either PORTRAIT LANDSCAPE-LEFT LANDSCAPE-RIGHT UNKNOWN UNKNOWN means not be locked.

• removeLockListener(function(orientation))

Functions

• lockToPortrait()
• lockToLandscape()
• lockToLandscapeLeft() this will lock to camera left home button right
• lockToLandscapeRight() this will lock to camera right home button left
• unlockAllOrientations()
• getOrientation(function(orientation))
• getDeviceOrientation(function(deviceOrientation))
• getAutoRotateState(function(state)) (android only)

orientation can return one of:

• PORTRAIT
• LANDSCAPE-LEFT camera left home button right
• LANDSCAPE-RIGHT camera right home button left
• PORTRAIT-UPSIDEDOWN
• UNKNOWN

Notice: PORTRAIT-UPSIDEDOWN not support at iOS now
