How to display count of rows in NSTableView

I am a cocoa newbie so I apologize if this is a stupid question.

I have a NSTableView that is being populated by a OpenPanel and all works ok.

Now I'd like to show the number of items in the NSTableView in a NSTextField. How do I get the number of items of the NSTableView? Do I use numberOfRowsInTableView?

Also, as a followup, what is the ideal way to catch updates to the NSTableView regardless how they happen, either from File Menu, Toolbar or drap and drop?

Thanks.

Best is just to ask your datasource. Your datasource is usually an array inside a view controller or at least an object that is a delegate to your tableview. 

[anArray count];

Gives you an integer. Given that you have hooked up your textfield, this is what you need :

myTextfield.text = [NSString stringWithFormat:@"%i", [anArray count]];

Simple as that.
