Question

Lately when I updated to xcode 4.3.2 I’ve run into numerous new problems. In my app view controller m file, I keep getting the error “cannot use super because it is a root clause.”

I’ve looked on the internet for hours, so any help would be appreciated.

Thanks

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:    (UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

Answer 1

When you declared your class, you probably forgot the superclass in the @interface line. For example, you did

@interface MyClass
{
    // ... ivars ...
}

// ... methods ...

@end

You want that first line to be:

@interface MyClass : NSObject

or whatever superclass you intended to use.
