Busy indicator is not displayed when used in iOS native embedding

[Balasubramanian Ramanathan]

I am trying to use SfBusyIndicator in .net native ios application using native embedding.

I have the code like this.

public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
{
        Window = new UIWindow(UIScreen.MainScreen.Bounds);

        MauiAppBuilder builder = MauiApp.CreateBuilder();
        builder.UseMauiEmbedding<Microsoft.Maui.Controls.Application>();
        builder.Services.Add(new Microsoft.Extensions.DependencyInjection.ServiceDescriptor(typeof(UIWindow), Window));
        builder.ConfigureSyncfusionCore();
        MauiApp mauiApp = builder.Build();
        MauiContext = new MauiContext(mauiApp.Services);

var vc = new UIViewController ();


SfBusyIndicator sf = new SfBusyIndicator
{
   IsRunning = true,
   BackgroundColor = Microsoft.Maui.Graphics.Colors.Green
};

var sfView = sf.ToPlatform(MauiContext);
sfView.Frame = Window!.Frame;
vc.View!.AddSubview(sfView);
Window.RootViewController = vc;
Window.MakeKeyAndVisible ();

return true;
}


when i run the application only the background color is displayed and the indicator is not displayed.

Does SfBusyIndicator work with native embedding?

Thanks

I was able to get it working by wrapping the SfBusyIndicator inside contentpage and contentpage.ToPlatform(mauContext).

When directly use the sfbusyindication.ToPlatform(), the rotating indicator is not centered. It is displayed at the top left.

Would be nice if we could use the SfBusyIndicator without wrapping inside ContentPage.

Is there a way to achieve this with native embedding?

Hi Balasubramanian,

We have reviewed your query, and we would like to inform you that you can set the Window frame value to the BusyIndicator frame. Now, the BusyIndicator works fine without wrapping it inside the ContentPage, as demonstrated in the code snippet below. Please review the attached sample and let us know the details.

Code Snippet :

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();

builder.Services.Add(new Microsoft.Extensions.DependencyInjection.ServiceDescriptor(typeof(UIWindow), Window));

 

MauiApp mauiApp = builder.Build();

_mauiContext = new MauiContext(mauiApp.Services);

 

 

        var vc = new UIViewController();

 

 

        SfBusyIndicator sf = new SfBusyIndicator

        {

            IsRunning = true,

            BackgroundColor = Microsoft.Maui.Graphics.Colors.Green,

 

 

        };

 

        sf.Frame = new Rect(Window.Frame.X, Window.Frame.Y, Window.Frame.Width, Window.Frame.Height);

        var sfView = sf.ToPlatform(_mauiContext);

        sfView.Frame = Window!.Frame;

        vc.View!.AddSubview(sfView);

        Window.RootViewController = vc;

        Window.MakeKeyAndVisible();

 

        return true;

 

      

    }

Thanks it is working as expected. It would be nice if could avoid setting the Frame

i mean this line 

        sf.Frame = new Rect(Window.Frame.X, Window.Frame.Y, Window.Frame.Width, Window.Frame.Height);

is not needed. Because i tried with SfCartesianChart and i dont need to set this frame. It would be nice if we could avoid setting this frame with SfBusyIndicator, which makes all of Sf control api consistent and same behaviour.
