I have a problem with "viewDidUnload" in Xcode 3.2.3 (I think)

Question

I have this:

- (void) viewDidUnload;
    [super viewDidUnload];

    self.cheatName = nil;
    self.description = nil;
}

It says that viewDidUnload is undeclared, no matter what I do with it. How do I declare it?

But If I have the brackets after the viewDidUnload function, then the problems increase from 1 to 4, with 2 having to do with @end function (WTF)

Anyone have a solution? I can upload the Xcode files and other stuff if you want.

This is in "DetailsViewController.m"

Answer 1

-[UIViewController viewDidUnload] was introduced in iOS 3.0. Prior to that version, it didn't exist. You're probably compiling against an SDK version prior to 3.0, say 2.2.1 or something like that. Because you call [super viewDidUnload], with the 2.x SDK the compiler doesn't know about this specific method so it is undeclared as far as the compiler knows.

So you'd have to install a newer version of the iOS SDK, current is 4.0.2.

Code needs to be like this:

- (void)viewDidUnload {
    [super viewDidUnload];

    self.cheatName = nil;
    self.description = nil;
}
