Assuming your NSTableView's columns are bound to an NSArrayController, you can bind the value of the NSTextField label to your array controller's with controller key "arrangedObjects" and with a key path of @count. If you want to bind the text field to something like "x rows" where x is the number of rows, you would bind the "Display Pattern Value1" to the same (arrangedObjects.@count) and use "%{value1}@ rows" as the Display Pattern.

Set up a fetch request on your managed object context like you normally would, and call countForFetchRequest:. Don't forget to subscribe to NSManagedObjectContextObjectsDidChangeNotification so you can update it when objects are added or removed!
