controlTextDidChange with 2 nstextfields - call different selectors

Question:

cocoa newbie here

i have 2 nstextfields connected with controlTextDidChange. it works fine.

- (void)controlTextDidChange:(NSNotification *)anotif{ [self eval]; }

when either of the textfields change eval is called.

what i want to do is check the textfield that changed and if it's the first one call eval1, if it's the second call eval2.

how can i do this?

Answer1:

Given that the NSTextFields are field1 and field2, all you have to do is check which one of them is the sender object, given along with the notification.

<strong>E.g.:</strong>

- (void)controlTextDidChange:(NSNotification *)anotif { if ([anotif object]==field1) { // field1 processing } else { // field2 processing } }

Answer2:

OK, I think I found it.

I set tags on both NSTextFields.

Then, I can get the tag number with :

[[anotif object] tag]
