react-native-orientation

Listen to device orientation changes in react-native and set preferred orientation on screen to screen basis.

Add it to your project

1. Run npm install react-native-orientation --save
2. Open your project in XCode, right click on your project and click Add Files to "Your Project Name"
3. Add RCTOrientation from your node_modules/react-native-orientation folder.
4. Open AppDelegate.h and add the following property @property (nonatomic) int orientation;
5. Open AppDelegate.m and add the following before the @end

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
  switch (self.orientation) {
    case 1:
      return UIInterfaceOrientationMaskPortrait;
      break;
    case 2:
      return UIInterfaceOrientationMaskLandscape;
      break;
    case 3:
      return UIInterfaceOrientationMaskAllButUpsideDown;
      break;
    default:
      return UIInterfaceOrientationMaskPortrait;
      break;
  }
}

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

Usage

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

Events

addOrientationListener(function)

removeOrientationListener(function)

Functions

lockToPortrait() lockToLandscape() unlockAllOrientations()

orientation can return either LANDSCAPE PORTRAIT UNKNOWN

TODOS

• Add some way to allow setting a preferred orientation on a screen by screen basis.
• Make API Cleaner to Orientation Locking
• [] Find a way to expose shouldAutoRotate (??? a PR would be great)
