SplashScreen Implementation : Issue in implmentation of splash screen

pnerkar

I created XIB for Splashscreen ( view : NsWindow , ViewContoller : NsWindowcontroller)

and using WillFinishLaunching

public override void WillFinishLaunching(NSNotification notification)
    {
        splashScreenController = new SplashScreenWindowController();

        if (splashScreenController != null)
        {
            if (splashScreenController.Window != null)
                splashScreenController.Window.OrderFrontRegardless();
        }


        Thread.Sleep(5000);
    }


  public override void DidFinishLaunching(NSNotification notification)
   {
        splashScreenController.Window.OrderOut(null);

  }


public partial class SplashScreenWindowController : NSWindowController
{
    #region Constructors


    public SplashScreenWindowController(IntPtr handle) : base(handle)
    {
    }

    // Call to load from the XIB/NIB file
    public SplashScreenWindowController() : base("SplashScreen")
    {

    }

    #endregion

    public override void WindowDidLoad()
    {
        base.WindowDidLoad();
        Window.HasShadow = false;
        Window.IsOpaque = false;
        Window.BackgroundColor = NSColor.Clear;
        Window.Level = NSWindowLevel.Status;
    }

    public new SplashScreen Window
    {
        get { return (SplashScreen)base.Window; }
    }
}
}

I am always getting null reference exception , Window is coming null

Please let us know if it is correct way to implement to Splash screen or if I am missing something

I am still getting null reference exception on WindowDidLoad , Window object is coming null, Below is my WindowController class and Splash window class

public partial class SplashScreenWindowController : NSWindowController
{
#region Constructors

    public SplashScreenWindowController(IntPtr handle) : base(handle)
    {
    }

    // Call to load from the XIB/NIB file
    public SplashScreenWindowController() : base("SplashScreen")
    {

    }

    #endregion

    public override void WindowDidLoad()
    {
        base.WindowDidLoad();
        Window.HasShadow = false;
        Window.IsOpaque = false;
        Window.BackgroundColor = NSColor.Clear;
        Window.Level = NSWindowLevel.Status;
    }

    public new SplashScreen Window
    {
        get { return (SplashScreen)base.Window; }
    }
}

//SplashWindow
public partial class SplashScreen : NSWindow
{
#region Constructors

    public SplashScreen(IntPtr handle) : base(handle)
    {

    }

    #endregion
}

Refer to the github sample , i convert it from swift to C#.

[Register("AppDelegate")]
public class AppDelegate : NSApplicationDelegate
{       

    public AppDelegate()
    {
    }

    public override void DidFinishLaunching(NSNotification notification)
    {

        SplashWindowController window = new SplashWindowController();
        window.ShowWindow(this);


        NSOperationQueue operationQueue = new NSOperationQueue();

        NSBlockOperation startUpCompletionOperation = NSBlockOperation.Create(() =>
        {

            NSOperationQueue.MainQueue.AddOperation(NSBlockOperation.Create(() =>
            {
                window.Close();

            }));
        });


        NSBlockOperation startUpOperation = NSBlockOperation.Create(() =>
        {
            Thread.Sleep(3000);
            operationQueue.AddOperation(startUpCompletionOperation);
        });


        startUpCompletionOperation.AddDependency(startUpOperation);            
        operationQueue.AddOperation(startUpOperation);


    }
}
