API Reference

Allowed orientations are 'portrait', 'landscape' and 'all'.

In order to force an orientation, hook the respective setCurrentOrientation methods at the pageLoad event of page, while make sure the method orientationCleanup is called at the navigatingFrom event of the page.

• setCurrentOrientation(orientation,callback)

  orientation is a string with possible values 'landscape' , 'portrait' and 'all' . Parameter callback is a function to call once the orientation is set, can be null.

• orientationCleanup()

  should be called on the navigatingFrom event if setCurrentOrientation is called, if this method is not called, can lead to inconsistent behavior.

Troubleshooting

In iOS , on iPad, if the plugin is not working, it is due to changes in the features supported by iPad. It is required for latest iOS to support multiple apps at the same time by screen sharing, which discourages locking of orientation in a particular mode. In order to make it work on iPad, set the key 'Requires Fullscreen' in xCode under app settings.
