macOS KeyDown event

[Gandolfmatt]

I'm currently playing with OpenGl in the cocoa framework of Xcode and I'm trying to get my app to detect if a arrow key is pressed. I've researched for hours today with hardly any luck, I have found other examples that worked and tried to duplicate their code into my project, but when I press a arrow key the computer beeps and nothing happens.

Anyone know a solution or could give me instructions of how to do it?

Doesn't something like this work?

-(void)keyDown:(NSEvent *)theEvent{
 printf("You pressed a key. Thank you, try again.");
}

Also, is your view configured to be firstresponder? Because if something else responds to the keydown before it gets to your code, you won't see the event.
