Hello...
Another approach would be to subclass NSNumberFormatter, and override the
- (BOOL)isPartialStringValid:(NSString *)partialString
newEditingString:(NSString **)newString errorDescription:(NSString
**)error;
method. That formatter method should be called for every character
entered into the textfield, and you can do whatever verification or
notification you want.
Once you've made your subclass of the formatter, just read the header
file into IB and you will be able to select it in the "custom class"
pane of the Interface Builder inspector for the formatter, so that
the formatter will be an instance of your subclass instead of the
standard NSNumberFormatter.

i am using controlTextdidChange but it does not work when I have the
textfield formatted to handle money or float values larger than 0 ... for some
reason It will not pick up the decimal
if i type in 1.2 it only recognized 12
any idea?
- (void)controlTextDidChange:(NSNotification *)aNotification

I want to capture a number being typed into an NSTextField number by
number including float values. Thus entering 1.2 would work like this
type 1 -> (calculations are done for the value 1)
type . -> (calculations are done for the value 1.)
type 2 -> (calculations are done for the value 1.2)
What delegate method should I use for this? I am also trying to use an
Interface Builder formatter on the NSTextField to keep the values positive.
Thanks in advance,
