I am just wondering about something with respect to the Model-View-Controller
(MVC) design pattern. Should any validation of input or output be done by the
model class which is handling and processing the data, or is validation more
properly a task to be assigned to a controller
. It's working so far.

I have a calculation project using buttons to input numbers into a UILabel. I
want it to format the numbers as they are entered to display grouping
separators. It has been a struggle but so far the best I have ben able to
achieve is this (I got the basic idea from a post at stackoverflow.com):
