I order to have a cutom navigation on a specific view on my app,
I create a Custom Navigation ios:

public class CustomNavigationPageRenderer : NavigationRenderer
 
 public override void ViewDidLoad()
 
 base.ViewDidLoad();

 UINavigationBar.Appearance.SetBackgroundImage(new UIImage(), UIBarMetrics.Default);
 UINavigationBar.Appearance.ShadowImage = new UIImage();
 UINavigationBar.Appearance.BackgroundColor = UIColor.Clear;
 UINavigationBar.Appearance.TintColor = UIColor.White;
 UINavigationBar.Appearance.BarTintColor = UIColor.Clear;
 UINavigationBar.Appearance.Translucent = true;
 
 

and a common interface class:

public partial class CustomPage : NavigationPage
 
 public CustomPage(): base()
 
 InitializeComponent();
 

 public CustomPage(Page root) : base(root)
 
 InitializeComponent();
 

 public bool IgnoreLayoutChange get; set; = false;

 protected override void OnSizeAllocated(double width, double height)
 
 if (!IgnoreLayoutChange)
 base.OnSizeAllocated(width, height);
 
 

Now, In my specific view, how have I use it?
I need to set on false the original navigation? (NavigationPage.SetHasNavigationBar(this, false);​)

public MySpecificViewNeedCustoNAv()
 {

 CustomPage myNavigationPage = new CustomPage();
 ...

need to set on false the original navigation?

No , you can refer the following code.

For example

Creating the Root Page in App.cs

public App ()

 MainPage = new CustomPage (new xxxpage());

Pushing Pages to the Navigation Stack in your page

async void ButtonClicked (object sender, EventArgs e)

 await Navigation.PushAsync (new xxxpage());
