title: How to turn iOS camera off
body: <p>I’m working on an IOS app in which video from the iPad's camera is displayed on a plane in an Away3D environment.</p>
  
  <pre><code>private function liveVideoCamera():void {
     liveCamera = getCamera(CameraPosition.FRONT); 
     liveCamera.setMode(1024, 730, 30);
  
     var cameraTexture:WebcamTexture = new WebcamTexture(570,340,8,true,liveCamera,true);
     var cameraMaterial:TextureMaterial = new TextureMaterial(cameraTexture);
  
     var planeGeom:PlaneGeometry = new PlaneGeometry(570, 340, 1, 1, false, true);
     cameraScreen = new Mesh(planeGeom, cameraMaterial);
     cameraScreen.y=210;
     cameraScreen.x=wall.x;
     cameraScreen.z=wall.z;
     cameraScreen.rotationY=90;
     scene.addChild(cameraScreen);
    } 
  </code></pre>
  
  <p>What I cannot find is a way to turn the camera off. Apple will not allow an app to operate the camera without user permission. The app is a puzzle game with more than one player allowed. I need new players to begin with the camera turned off if a previous player left it turned on.</p>
  
  <p>I have found several suggestions on the web that say to set the video attached to the camera to null. But as you can see there is no video:Video involved in the method. The camera outputs to cameraTexture:WebcamTexture instead.</p>
