Integrating .NET MAUI PDFViewer with native ios application

In this article, learn to use the .NET MAUI PDF viewer control in a native ios application and view a PDF document.

Step 1:

Create a new .NET ios Application and install the Syncfusion.Maui.PdfViewer nuget package from nuget.org.

Step 2:

In the project file of the native application, add <UseMaui>true <UseMaui> to enable the .Net Maui support demonstrated as follows. i.e. It tells the build system that your project is a .NET MAUI application and should be treated accordingly.

<PropertyGroup>
 <TargetFramework>net10.0-ios</TargetFramework>
 <OutputType>Exe</OutputType>
 <Nullable>enable</Nullable>
 <UseMaui>true</UseMaui>
 <ImplicitUsings>enable</ImplicitUsings>
 <SupportedOSPlatformVersion>15.0</SupportedOSPlatformVersion>
</PropertyGroup> 

Step 3:

To initialize .NET MAUI in a native app, create a MauiAppBuilder object and invoke UseMauiEmbeddedApp () to enable embedding. Then, configure it to setup SyncfusionCore component within your .NET native app project.

Then, create a MauiApp object by invoking the Build() method on the MauiAppBuilder object. In addition, a MauiContext object should be made from the MauiApp object. The MauiContext object will be used when converting .NET MAUI controls to native types.

public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
{
     // create a new window instance based on the active scene
     UIWindowScene? windowScene = application
      .ConnectedScenes
      .OfType<UIWindowScene>()
      .FirstOrDefault();

     if (windowScene != null)
     {
         Window = new UIWindow(windowScene);
         Window.RootViewController = new UIViewController();
         Window.MakeKeyAndVisible();
     }
     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:

Create a folder named Assets in your project, add the required PDF file to this folder, and set the PDF file's build action to Embedded resource in its properties to view pdf in the SfPdfViewer control.

Step 5:

Initialize the SfPdfviewer control. Converts the SfPdfviewer control to a compatible ios UIView. Creates a UIViewController, adds the PdfViewer to its subview, and assigns it the root view controller of the main window. Makes the main window visible.

public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
{
   .....
   .....
   // Create the PDF Viewer
   SfPdfViewer pdfViewer = new SfPdfViewer();
   pdfViewer.Background = Colors.White;
   // Load a PDF document
   var assembly = Assembly.GetExecutingAssembly();
   pdfViewer.DocumentSource = this.GetType().Assembly.GetManifestResourceStream("PDFViewerNativeEmbeddingiOS.pdfSuc_1.pdf");
   
   // Convert the .NET MAUI control to an iOS View object
   UIView mauiView = pdfViewer.ToPlatform(_mauiContext); 
   mauiView.Frame = Window!.Frame;
   // Create UIViewController and add the PDF Viewer to its subviews
   var vc = new UIViewController();
   vc.View!.AddSubview(mauiView);
   // Set the UIViewController as the root view controller
   Window.RootViewController = vc;
   // Make the window visible
   Window.MakeKeyAndVisible();
   return true;
} 

Step 6:

In the solution, set the native ios project as the start-up project. Build, deploy and run the project.
