Try using
[text2 setStringValue:[NSString stringWithFormat:@"%i", [[textField1
stringValue] length]]];
Using setIntValue on a text field won't set the text field's
stringValue to be a string from that int.

Still struggling with documentation!
Simple task. I have two text fields (text1 & text2) and all I'm
trying to achieve is to put into text2 a number specifying how many
characters there are in the text in text1.
I started with:
[text2 setStringValue:[text1 stringValue]];
..just to make sure I was on the right track and it successfully
placed a copy of the text1 text into text2. Now all I needed was to
change the code to put the character count instead.
I looked at the documentation and under NSString I found:
Getting a String’s Length
• – length
• – lengthOfBytesUsingEncoding:
• – maximumLengthOfBytesUsingEncoding:
So I click on 'length' and was told that this 'Returns the number of
Unicode characters in the receiver.' Not sure if that's the same
thing as just counting characters but changed my code to:
[text2 setStringValue:[text1 length]];
and got ...'warning: passing argument 1 of 'setStringValue:' makes
pointer from integer without a cast'
..so assuming this means I was trying to place a number into a text
field, I changed the code to:
[text2 setIntValue:[text1 length]];
It compiled and linked fine but the code didn't put anything into
text2!
Where am I going wrong?_______________________________________________
