How to integrate .NET MAUI Tab View with iOS native embedding?

In this article, you can learn how to create a .NET MAUI Tab View 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 .NET MAUI support, as demonstrated below.

<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 Tab View 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:

Convert the Tab View into a UIView compatible with the Maui platform. Create a UIViewController, add the Maui Tab View to its sub view, and set 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();
   ...
}
