How to integrate .NET MAUI TabView with iOS native embedding?

In this article, you can learn how to create a .NET MAUI TabView native-embedded iOS application by following the step-by-step process explained as follows:

Step 1:

Create a .NET iOS application and install the Syncfusion.Maui.TabView Nuget package.

Step 2:

In the project file of the native application, add <UseMaui>true</UseMaui> to enable the .NET MAUI support demonstrated as follows.

<PropertyGroup>
. . .
  <Nullable>enable</Nullable>
  <UseMaui>true</UseMaui>
  <ImplicitUsings>enable</ImplicitUsings>
. . .
</PropertyGroup>

Step 3:

Creating a MauiAppBuilder object and using the UseMauiEmbedding function is the standard procedure for initializing .NET MAUI in a native app project.

Use the Build() method on the MauiAppBuilder object to build a MauiApp object. From the MauiApp object, a MauiContext object should be created. Converting .NET MAUI controls to native types will involve using the MauiContext object.

MauiContext? _mauiContext;
public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
       // create a new window instance based on the screen size.
       Window = new UIWindow(UIScreen.MainScreen.Bounds);
       MauiAppBuilder builder = MauiApp.CreateBuilder();
       builder.UseMauiEmbedding<Microsoft.Maui.Controls.Application>();
       builder.ConfigureSyncfusionCore();
       // Register the Window.
       builder.Services.Add(new Microsoft.Extensions.DependencyInjection.ServiceDescriptor(typeof(UIWindow), Window));
       MauiApp mauiApp = builder.Build();
       _mauiContext = new MauiContext(mauiApp.Services);
}

Step 4:

Initialize the TabView control.

MauiContext? _mauiContext;
public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
   ...
   SfTabView tabView = new SfTabView();

   ListView listView = new ListView
   {
       RowHeight = 50,
       ItemsSource = new string[] { "James", "Richard", "Clara", "Michael", "Alex", "Clara" },
       ItemTemplate = new DataTemplate(() =>
       {
           var grid = new Grid
           {
               Margin = new Thickness(10, 5)
           };
           var label = new Label
           {
               ...
           };
           label.SetBinding(Label.TextProperty, ".");
           
           grid.Children.Add(label);
   
           return new ViewCell { View = grid };
       })
   };
   
   Grid favoritesGrid = new Grid { };
   favoritesGrid.Children.Add(listView);
   ...
   var tabItems = new TabItemCollection
   {
       new SfTabItem()
       {
           Header = "FAVOURITES",
           Content = favoritesGrid
       },
       ...
   };
   
   tabView.Items = tabItems;
   ...
}

Step 5:

Converts the Tab View into a UIView compatible with the Maui platform. Creates a UIViewController, adds the Maui Tab View to its sub view, and sets it as the root view controller of the main window. Makes the main window visible.

public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
{
   ...
   UIView mauiView = tabView.ToPlatform(_mauiContext);
   mauiView.Frame = Window!.Frame;

   // create UIViewController 
   var vc = new UIViewController();
   vc.View!.AddSubview(mauiView);

   Window.RootViewController = vc;

   // make the window visible
   Window.MakeKeyAndVisible();
   ...
}
