Still struggling with documentation!
That might be because the documentation makes the reasonable
assumption that you already know how to use C and Objective-C.
You're not recognising the difference between the data types 'int'
and 'pointer to object'. The text field expects a pointer to an
NSString. Telling it to setIntValue:someInt is just you hoping
it'll work.
What you need to do is [text2 setStringValue:[NSString
stringWithFormat:@"%d", [text1 length]]];
You should read the documentation, paying attention to method
return types and etcetera. Also, bone up on basic C. It will
help a lot.
I'm trying! Honest! I've studied 'Learn C for Cocoa' at http://
cocoadevcentral.com/articles/000081.php, and a C programming book,
as well as looking up stuff on the Web but it's a very slow
process. The fact that I'm dyslexic doesn't help (although that's
not a good excuse) as I need to go over things again and again to
'get' them ... although once I've 'got it', it tends to stay put!
Getting there. Slowly.
OK, sorry. I think I got out of the wrong side of bed that morning.
As it turns out, the 'solution' I posted was wrong anyway. [text1
length] won't work because an NSTextField doesn't respond to
'length'. It should be [[text1 stringValue] length]
Happy coding,
Ron
