This declares stringLength as a pointer to an int. You don't want it
to be a pointer, it should just be an int. So, remove the asterisk.
For somebody learning C and Objective-C at the same time, it can be
confusing. On the one hand, most Objective-C objects are stored into
explicit pointer variables (except "id" where the pointerness is
implicit). On the other hand, many of the C standard types are not
pointers to objects -- they are just "scalars". I think you need to
review the basics of C.
[textLabel setStringValue:@"\"[EMAIL PROTECTED]" is %d characters long", string,
stringLength]; //error: too many arguments to function
'setStringValue:'
NSLog(@"%@", string);
}
