API Usage

Call CrossDeviceOrientation.Current from any project or PCL to gain access to APIs.

/// <summary>
/// Gets current device orientation
/// </summary>
DeviceOrientations CurrentOrientation { get; }

When device orientation is changed you can register for an event to fire:

/// <summary>
/// Event handler when orientation changes
/// </summary>
event OrientationChangedEventHandler OrientationChanged;

You will get a OrientationChangedEventArgs with the orientation type:

public class OrientationChangedEventArgs : EventArgs
{
	public DeviceOrientations Orientation { get; set; }
}

public delegate void OrientationChangedEventHandler(object sender, OrientationChangedEventArgs e);

The DeviceOrientations enumeration has these members.

Call LockOrientation for set orientation and lock with disabling device auto-rotation:

/// <summary>
///     Lock orientation in the specified position
/// </summary>
/// <param name="orientation">Position for lock.</param>
void LockOrientation(DeviceOrientations orientation);

For disable the lock, call UnlockOrientation method:

/// <summary>
///     Unlock orientation
/// </summary>
void UnlockOrientation();

iOS Specific Support

Add this code for your ViewController where you want locking orientation:

public override bool ShouldAutorotate()
{
	// set plugin for handle of this method
	return DeviceOrientationImplementation.ShouldAutorotate;
}

public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
{
	// allow all orientations
	return UIInterfaceOrientationMask.AllButUpsideDown;
}

In your Info.plist need set all device orientations.

Xamarin.Forms iOS

If you want to lock orientation for the entire iOS application.

Add this code in your AppDelegate.cs:

[Export("application:supportedInterfaceOrientationsForWindow:")]
public UIInterfaceOrientationMask GetSupportedInterfaceOrientations(UIApplication application, IntPtr forWindow)
{
    return DeviceOrientationImplementation.SupportedInterfaceOrientations;
}

Note: In this case, to lock/unlock orientation on the one screen, you must use the LockOrientation/UnlockOrientation methods.

Xamarin.Forms Android

In your MainActivity.cs, add overriding for changing orientation as here:

public override void OnConfigurationChanged(Configuration newConfig)
{
    base.OnConfigurationChanged(newConfig);

    DeviceOrientationImplementation.NotifyOrientationChange(newConfig.Orientation);
}

Note: This solution has only two state Portrait and Landscape.
