I'm on chapter 5 of Aaron Hillegass Cocoa 3rd edition and I'm trying
to do the challenge page 90.
In Xcode, when I option double-click on stringValue & setStringValue
I get the following:
- (NSString *)stringValue
- (void)setStringValue:(NSString *)string
Question 1:
Why are these two methods of NSTextField class defined in different
ways?
These methods are not defined in different ways. These _are_ different
methods. The first one is a getter (to retrieve the value "stored" in
the stringValue-Property NSTextField), and the second one is a setter
(to set the stringValue-Property of NSTextField).
Question 2:
Can someone give me an example of how to implement stringValue?
NSString *_aString = [myNSTextField stringValue];
I can implement setStringValue like this to change the text of
field1 to the text in field2:
[field1 setStringValue:field2];
Question 3:
I know programmer-speak is much more efficient for you all than
something that would explain my questions above: does anyone know of
a good reference that would come down to my level?

Thanks so much for your help,
