Question

I have the following code for my universal app but I’m getting this weird log when I run the app. Everything seems to be working fine, however.

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    if (NSClassFromString(@"UISplitViewController") != nil && UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) 
    {
        return YES;
    }
    else
        return NO;
}

In the console:

The view controller <UINavigationController: 0x1468d0> returned NO from -shouldAutorotateToInterfaceOrientation: for all interface orientations. It should support at least one orientation.

Answer 1

The message says everything:

It should support at least one orientation.

In your else statement, NO is returned independently of the orientation. If NO here means “portrait only”, do the check and return YES for portrait:

else
 return
  (interfaceOrientation == UIInterfaceOrientationPortrait) ?
    YES :
     NO ;

Or the more succinct (but less fancier) version:

else
  return (interfaceOrientation == UIInterfaceOrientationPortrait);
