Okay, I've done this:
[labelField setstringValue:[textField StringValue]];
However, when I build it, and I type something in and then press
the button,
the string doesn't show up on the labelField IBOutlet.
How can I resolve this?
Ok, Cocoa is case sensitive. What this means is that stringValue is
not the same thing as StringValue.
All methods in Cocoa follow the naming convention of starting lower
case and having each word after that uppercase
likeThis:
So basically, stringValue: and setStringValue: are the methods you
need to use.
What Omar said.
Let me add one simple rule, though:
If the compiler generates a warning, you are doing it wrong.
The above expression would normally generate two warnings telling you
that the methods -setstringValue: and StringValue do not exist. Make
the warnings go away properly and the problem would be resolved.
The compiler's error and warning messages are often a bit obtuse, but
it really is trying to help by pointing out code that is very unlikely
to work at runtime.
