It's this line
[textLabel setStringValue:@"\"%@\" is %d characters long", string,
stringLength];
The setStringValue function does not take more than one argument. If you
want to format the string like that try
[textlabel setStringValue: [NSString stringWithFormat:@"\"%@\" is %d
characters long", string, stringLength] ]

If you can't be kind, at least have the decency to be vague.
