Question

I am making my first Mac OS X application and I’m stuck with a problem.

I created a NSTableView on my window linked to a NSArrayController and I’d like to call a method after stopping to edit a textfield cell. So I’ve selected to call an action when end editing, as you can see in the following screenshot:

After, I’ve created an IBAction for it:

It generated this code in my AppDelegate.h:

- (IBAction)stopEditingHeaderNameCell:(id)sender;

And then I edited the IBAction in AppDelegate.m in order to show a NSLog message when the cell is edited:

- (IBAction)stopEditingHeaderNameCell:(id)sender
{
    NSLog(@"test");
}

However, when I stop editing the cell by pressing enter or clicking in another element, nothing happens. I already tried to apply this IBAction to a NSTextField and it works perfectly, but it doesn’t call the IBAction when applied to this text field cell.

Can anyone help me to solve this?

Thanks!

This is not the way you do this with text field cells in a table view. You need to make your app delegate the delegate of the table (you can connect this in IB), and then implement controlTextDidEndEditing:. This method will be called when you end editing (by tabbing out of the cell or clicking on another row or column).
