Currency Converter Tutorial


  • Subject: Currency Converter Tutorial

I tried to do the Currency Converter Tutorial (in /Developer/Documentation/Cocoa/Conceptual/ControllerLayer of 10.3).

But the method amountInOtherCurrency gets called only once (at the very start, when everything is still 0.0 ).

When I change the exchange rate later, the appropriate methods get called, but not amountInOtherCurrency.

And how should it? How should the NSObjectController know that this value has anything to do with the exchange rate or the dollarAmount?

Obviously something is missing. Either in the tutorial, or in my understanding.

I seem to remember having read about this in this list before, but I failed to find this reference searching mamasam.

Maybe someone could enlighten me.

Gerriet.
