I would love to do something to reward the user visually when they match two text fields as they type. This is jQuery-esque, and I'm not sure if it's possible in Objective-C/Xcode. The key here is "AS THEY TYPE". Some web-based user account setup forms show a green checkbox when the password/confirmPassword (mainly because of the secure field formatting •••••) or email/confirmEmail form fields match or turn into a red "X" if the passwords lose their match.
Is there anything similar to an onKeystroke event in Objective-C/Xcode?
I'm willing to research and learn this. I just don't know how to correctly reference this type of functionality.

What you're looking for is to implement the following in your text view and buffer the keystrokes and compare them with your text field.
- (void)keyUp:(NSEvent *)theEvent
