Project Description

In "iPhoneUnitTests" sample code, there is Calculator class in CalculatorLib/Calculator.h. This class has very simple calculator functions, but I need "basic" calculator functions as in Calculator App in Mac OS (I don't need complex function, all I need is functions when you change "view" to "basic" in the Calculator App and "AC").
