title: How can I check if NSTextField did change value in C#?
body: <p>I created a Cocoa application in C# (using Xamarin.Mac) and I want to check if NSTextField did change the value. I couldn't find a lot of tutorials about this in C#, and the methods found for swift or overrides doesn't work for me. I tried this : </p>
  
  <pre><code> public override void ObjectDidEndEditing(NSObject editor)
  </code></pre>
  
  <p>and </p>
  
  <pre><code> public override void DidChangeValue(string forKey)
  </code></pre>
