How can I pass data between views via segue in a Xamarin.mac Cocoa app?

Question

I am developing a Xamarin.Mac Cocoa app in C# with visual studio for Mac.

I would like to pass an object from my first view controller to the next view controller. I have a segue called LaunchSecondView that starts the second view. And I need an object class Person from the first view in the second.

First, you need to set a public property in your second view controller :

public Person MainPerson { get; set; }

You’ll need to override the method called PrepareForSegue. Inside it, you identify the destination controller (your second view), and in case you have multiple segues, it is a good practice to use a switch case statement.


public override void PrepareForSegue(NSStoryboardSegue segue, NSObject sender)
{
    base.PrepareForSegue(segue, sender);

    switch (segue.Identifier)
    {
        case "LaunchSecondView":
            {
                SecondViewClass target = segue.DestinationController as SecondViewClass;
                target.Person = CurrentPerson;
            }
            break;
    }
}
