I think mmalc got me right. Sorry again for my initial mail which was a little
confusing. When I wrote the mail I confused Cocoa Bindings with target/action,
because what I've been doing is, I just connected the selector of one view
TextField) to the takeIntegerFrom IBAction of another one (Stepper) and vice
versa. Actually I'm pretty sure I read this in a book.
Anyways, obviously this is bad practice and I've been doing it "right", I was
just wondering whether there is a more convenient way since I got 4 pairs of
Steppers/TextFields in my app. My action method looks kind of like
if (sender == firstStepper) {...}
else if (sender == secondStepper) {...}
...
In the target controller I don't have IBOutlets for those steppers and
textfields. Those are in another (mediating) controller. Question is whether
there is another way to do this instead of defining outlets also in the target
controller. I guess assigning tags to each stepper/textfield and defining an
enum for them would be an option?
Cheers,
Chris
