NSMatrix simple binding question

问题

I am trying a sample application in which I have taken following controls:

i. NSMatrix (with 2 elements, serving as radio button)

ii. Button (which when clicked generates action based on radio button selected)

My questions are-

In IB, can we bind each button cell of NSMatrix to a single bool variable, say- firstElementValue, such that when user selects first button cell in NSMatrix, firstElementValue is YES and when user selects second button cell in NSMatrix, firstElementValue is NO.

or

Is there any other effective way to achieve this ?

Please suggest.

Thanks,

Miraaj

I resolved it by setting NSNegateBoolean as value transformer for one of the radio button cells :)
