I am doing a CustomTabbedRenderer to set the tabbar at the top of the page on iOS.
These TopTabbedBar is nested as a tab of a root tabbedpage.

I first get what I want (see the image):
right layout
But when I select another tab, the Page.ContainerArea is resized (see the image) , and the coontrol is behind the tabbar.
bad layout

public class TabbedPageCustomRenderer : TabbedRenderer

{

        bool _loaded;

        Size _queuedSize;







        Page Page => Element as Page;





        public override void ViewDidLayoutSubviews()

        {

            base.ViewDidLayoutSubviews();



            if (Element == null)

                return;



            if (!Element.Bounds.IsEmpty)

            {   

        // I add "(loat)10" to shift the View.Frame under the statusbar



                View.Frame = new System.Drawing.RectangleF((float)Element.X, (float)10, (float)Element.Width, (float)(Element.Height-10));

            }



            var tabBarFrame = TabBar.Frame;



            var frame = ParentViewController != null ? ParentViewController.View.Frame : View.Frame;

            var height = frame.Height - tabBarFrame.Height;



        // I add "tabBarFrame.Height" to shift the "Page.ContainerArea" under the Tabbar

            Page.ContainerArea = new Rectangle(0, tabBarFrame.Height, frame.Width, height);





            if (!_queuedSize.IsZero)

            {

                Element.Layout(new Rectangle(Element.X, Element.Y, _queuedSize.Width, _queuedSize.Height));

                _queuedSize = Size.Zero;

            }



            _loaded = true;

        }



        public override void ViewWillLayoutSubviews()

        {

            base.ViewWillLayoutSubviews();

            this.TabBar.InvalidateIntrinsicContentSize();





            nfloat tabSize = 44.0f;



            UIInterfaceOrientation orientation = UIApplication.SharedApplication.StatusBarOrientation;



            if (UIInterfaceOrientation.LandscapeLeft == orientation || UIInterfaceOrientation.LandscapeRight == orientation)

            {

                tabSize = 32.0f;

            }



            var tabFrame = this.TabBar.Frame;

            tabFrame.Height = tabSize;

            tabFrame.Y = View.Frame.Y;

            this.TabBar.Frame = tabFrame;



            //this.TabBar.TopAnchor = false;

            this.TabBar.Translucent = false;

            this.TabBar.Translucent = true;

        }

    }

I find out when tapping on a new tab, that the "SafeAreaInsets" is been reset. May be it is the problem.

Can you help me, please.
