Hello,
I have a question about UITextField -
How might I restrict/correct user input that is numerical? For
instance, I would like the input to only be numbers, and to have an
upper bounds.
If a user inputs any non-numerical input, I want to send a message to
the UITextField to set itself

How do you prevent an NSTextField from accepting anything aside from
numbers? Or will I need to code up a solution to remove text from the
field automatically? Display a dialog & clear the contents?
Thanks,

Thanks for the RTFM.
It looks like you can no longer get an NSNumberFormatter from the
Views pane in Interface Builder & wire it up as was ( recent? )
convention. Is there still a way to do this? I'm not even sure how

So my options are ( if I'm looking in the right place ) on the Text

Hello,
I'm trying to better acquainted with Cocoa and Obj-C, having some
trouble with simple things. Perhaps someone could kindly apply cluebat
to skull for me.
I'm accepting a couple of string values from a pair of NSTextField and
would like to take these values and do some math with them, then
11 matches
