In Forms Project;
Dependency;
using Xamarin.Forms;
namespace MyProject
{
public static class MBDGeneralMethods

static IMBDGeneralMethods _instance;
public static IMBDGeneralMethods Instance {
get{
if (_instance == null) {
_instance = DependencyService.Get<IMBDGeneralMethods> ();

}
}
}

using System;
namespace MyProject
{
public interface IMBDGeneralMethods
{
void ForceLandscape();
void ForcePortrait();
void SetOrientionFree();
}
}
How to call it from any page;
In OnAppearing or in OnSizeAllocated or anywhere you want;
protected override void OnSizeAllocated(double width, double height)
{
base.OnSizeAllocated(width, height); //must be called
MBDGeneralMethods.Instance.ForceLandscape();
}
In iOS Project;
Info.plist;
AppDelegate.cs;
[Export("application:supportedInterfaceOrientationsForWindow:")]
public UIInterfaceOrientationMask GetSupportedInterfaceOrientations(UIApplication application, IntPtr forWindow)
{
return UIInterfaceOrientationMask.AllButUpsideDown;
}
