Time for action – controlling the position of the camera roll


Use the following steps to change the position of the default camera roll dialog box on an iPad:

  1. Go to the merges/ios/js folder of the PhoneGap project you previously created, open the index.js file, and add a new function named initAdditionalOptions.

    initAdditionalOptions: function(){
    
        // Additional options will be defined here
    
    }
  2. In the body of the initAdditionalOptions function, specify the device photo album as source of the getCamera method as well as the size and position of the popover dialog box.

    app.cameraOptions.sourceType = Camera.PictureSourceType.SAVEDPHOTOALBUM;
    
    app.cameraOptions.popoverOptions = new CameraPopoverOptions(220, 600, 320, 480, Camera.PopoverArrowDirection.ARROW_DOWN);
  3. Add a call to the initAdditionalOptions function at the end of the deviceready event handler.

    deviceready: function() {
        // All the events handling initializations are here
        app.initAdditionalOptions();
    
    }
