Xamarin Forms iOS TitleBarTextColor not changing - xamarin

Question

To change the TitleBarTextColor so far I tried a lot and my code now does change the back button color and the area on the very top of the screen, but the title!
in my AppDelegate FinishedLaunching function (it's after Forms.Init() and before LoadApplication()):
UINavigationBar.Appearance.SetTitleTextAttributes(new UITextAttributes
{
TextColor = UIColor.White
});
In my ViewModel:
(App.Current.MainPage as NavigationPage).BarBackgroundColor = Color.FromHex("#990000");
(App.Current.MainPage as NavigationPage).BarTextColor = Color.White;
And this is how I'm navigating between the pages (not all the pages):
await _navigationService.NavigateAsync(new Uri("http://wwww.x.com/NavigationPage/TabbedNavigationPage?selectedTab=XPage/Document", UriKind.Absolute));
I even try to call the ViewModel code after the Prism navigation but it doesn't work... I'm a beginner and don't fully comprehend Prism and or Xamarin Forms.
[EDIT] -> I also tried to create a new class and inherit it from NavigationPage, set the BarTextColor in its constructor and use that class in the navigation like this: await _navigationService.NavigateAsync(new Uri("http://wwww.x.com/NEWCLASSCREATED/TabbedNavigationPage?selectedTab=XPage/Document", UriKind.Absolute)); But, as you may know, it is still not working.
Here's a Image ;)

Answer 1

So I finnaly managed to work this out...
What I had to do was to create a custom Content Page because all the other solutions wasn't working. So I created this custom renderer only in my iOS project:
[assembly: ExportRenderer(typeof(ContentPage), typeof(CustomContentPageRenderer))]
namespace TestProject.iOS.Bll.Utils.Renderers
{
public class CustomContentPageRenderer : PageRenderer
{
public override void DidMoveToParentViewController(UIViewController parent)
{
base.WillMoveToParentViewController(parent);
var titleView = new UITextView();
var page = this.Element as ContentPage;
try
{
if (!string.IsNullOrEmpty(page.Title))
{
titleView.Text = page.Title;
titleView.TextColor = UIColor.White;
titleView.Font = UIFont.SystemFontOfSize(17, UIFontWeight.Regular);
var bgColor = page.BackgroundColor;
titleView.BackgroundColor = UIColor.FromRGBA((int)bgColor.R, (int)bgColor.G, (int)bgColor.B, 0);
parent.NavigationItem.TitleView = titleView;
parent.NavigationItem.TitleView.ContentMode = UIViewContentMode.ScaleAspectFit;
}
}
catch (Exception e)
{
}
}
}
}
And I also removed all the code that I puted before in my AppDelegate file and in the App.xaml.cs file as well. I left the codes from the ViewModels because it was changing the back button to white, and I deleted the new NagivationPage class that I created before.
I'm going to explain why I did some of the things that you saw there:
To change the Title I created a UITextView() and set it to my NavigationItem.TitleView of the parent page. I set titleView.Text = page.Title; because my original page already have a title, so I'm just reusing it. And the backgroundcolor I had to do all of that so the backgroundcolor property works just in the way that I wanted.
And this DidMoveToParentViewController function was just so it can do all that before NavigationAsync from Prism.
