Now why doesn't value have anything in it? Or what is the best way to
store the information
in the NSTextView. I don't need any formatting information.
Lance,
I had a look to the doc for NSText string:
"Returns the characters of the receiver's text. For performance
reasons, this method returns the current backing store of the text
object. If you want to maintain a snapshot of this as you manipulate
the text storage, you should make a copy of the appropriate substring."
So, I suggest you make a copy of the string in updateNSTextFieldAction
with, for instance, NSString stringWithString:.
value = [NSString stringWithString:[textViewOutlet string]];
NB: I am brand new to Cocoa. Please forgive me if this is all wrong but
it's a good way for me to learn too.
Fred
