Actually, you bind the text field to the property "feedback" of some
object (File's Owner?). When you start using array properties, getting
this terminology right will help you avoid a *lot* of grief.
(Sometimes a property of an object is really an object, sometimes it's
not.)
exposed as an Objective-C 2.0 property,declared like this:
@property (retain, nonatomic) NSMutableString *feedback;
In my implementation, use @synthesize to have it build the accessors
and mutators. The binding is set to Continuously Updates Values, and
is not editable, and has rich text turned off. If I run my program,
and make changes to the string (feedback), those are not reflected
in the text field even though I can tell through the debugger that
the string is changing.
Make changes how? If you're doing 'someObject.feedback = newString',
the text field should update. If you're doing (in a someObject method)
'feedback = newString', the text field won't update unless you enclose
it in willChangeValueForKey/didChangeValueForKey.
