Xcode interface builder

Question

I am using the xcode interface builder to build the UI, when I drag the touch event to header file, it generates following code in my C# project
file

x.designer.cd
[Action ("NextAction")]
partial void NextAction (Foundation.NSObject sender)

I also see it in both the header file and the m file, but the x.cs file does not generate any touch code in

x.cs file anymore. I am wondering if it is a bug or i am doing wrong using the xcode interface builder. I have say the current xamarin tutorial is not up to date anymore, specially the event binding part.

Hi marc-8366,

Welcome to our Microsoft Q&A platform!

About Designing user interfaces with Xcode, you can refer to this document.

Usually, we only need to drag the control into the .h file as follows.

@property (nonatomic, retain) IBOutlet UIButton *btn;  

which will generate the corresponding code in designer.cs.

[Outlet]  
UIKit.UIButton btn{get; set;}  

And now, you can subscribe to the event in ViewDidLoad.

public override void ViewDidLoad()  
{  
    base.ViewDidLoad();  
      
    btn.TouchUpInside += Btn_TouchUpInside;  
}  
  
private void Btn_TouchUpInside(object sender, EventArgs e)  
{  
    Console.WriteLine("Btn test");  
}  

Regards,
Kyle
