    ToolbarResource = Resource.Layout.Toolbar;
     
    base.OnCreate(bundle);
     
    global::Xamarin.Forms.Forms.Init(this, bundle);
     
     
    var width = Resources.DisplayMetrics.WidthPixels;
    var height = Resources.DisplayMetrics.HeightPixels;
    var density = Resources.DisplayMetrics.Density; //
     
    App.ScreenWidth = width / density; //
    App.ScreenHeight = height / density; // 24 OnSizeAllocated
     
    LoadApplication(new App());
    }
    IOS下 AppDelegate.cs里面添加:
    public override bool FinishedLaunching(UIApplication app, NSDictionary options)
    {
