I am a total newbie to everything Cocoa. I don't have a book on C yet although C Primer Plus just shipped. I don't have Learning Cocoa although it is on order. My last language was Fortran. I have successfully completed the CurrencyConverter tutorial.

As a second project I just wanted to convert the CurrencyConvert into a simple calculator that would take the numbers in the two fields and perform the function designated by a radio button (add, subtract, multiply, divide).

I set up an ArithmeticController object to interact with the interface and to call the appropriate arithmetic model object (I took the Model-Controller bit pretty seriously ). I have four model objects; one for each function.

That is the background. The question is, how do I determine which radio button is selected? I have set up a case routine and just want to evaluate the radio button selection. Do I have to 'connect' the ArithmeticController to the radio buttons and make an 'outlet' for the radio buttons in the ArithemeticController object?

Please excuse my ignorance as I am just getting started with OOP and PB/IB.

Thanks,

Check out the SimpleCocoaApp source, I think going through the code may help you with radio button questions:

Thanks. I hadn't run across that tutorial yet. I'll give it a whirl tonight.
