Really Stuck on Screen Rotation iOS 6, I Need a xib locked to portrait - objective-c

Question

Having read every method of handling screen rotation in IOS 6 on here, Apple documents, and fierce Googling, after days and days I am still stuck on this when using xibs.
What im trying to achieve is have a few iPad only xibs, in landscape only, rest of app is portrait.
If I was using storyboards I understand how to subclass the nav controller to override the rotation but I am NOT, im using xibs and would appreciate any input how this works with xibs
In my app delegate:
ICHomeController *homeController = [[ICHomeController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:homeController];
navController.navigationBarHidden = YES;
navController.navigationBar.barStyle = UIBarStyleBlackOpaque;
navController.navigationBar.tintColor = [UIColor grayColor];
self.navigationController = navController;
[self.window setRootViewController:self.navigationController];
[self.window makeKeyAndVisible];
return YES;
In addition to trying what seems like every solution on here Ive tried the obvious in my vew controllers, but as I understand in iOS 6 it doesn't get called.
// Older versions of iOS (deprecated)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation);
}
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationLandscapeLeft;
}

I've been battling with this for days too with a more complex navigation structure.
The basic rule seems to be that the ROOT controller, whether it be a UINavigationController, UITabBarController or just a simple UIViewController, takes control of the rotation. So as you PUSH UIViewControllers onto the stack, the very first one still controls the rotation.
If you use a modal view, then this model view will be considered the ROOT of the stack until it is dismissed. So if you show a modal UIViewController then push views on top of it, the UIViewController that was presented as the modal view is in control of the rotation.
Just make sure for modal views to use presentViewController:animated:completion.
The easiest way to get certain views to be in a different rotation, is present it modally.
If this can't be avoided, then go right back to your first view or nag controller and set the rotations.
Add some NSLog(#"%s", __FUNCTION__); statements to your rotation methods to see which ones are being called.
In your code above, only the first method is the old iOS5 (Now deprecated) method. The other 3 are the new iOS 6 methods.
Using your example code above, you would need to subclass the UINavigationController. To do this create a new class as a UINavigationController subclass with a different name eg. MyNavigationController and add the rotation methods to it. Then in your code above instead of using
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:homeController];
You would use:
MyNavigationController *navController = [[MyNavigationController alloc] initWithRootViewController:homeController];
Also, make sure you have allowed orientations selected here:

I had the same problem. Here's what worked for me in 5 and 6.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
- (BOOL)shouldAutorotate NS_AVAILABLE_IOS(6_0)
{
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation NS_AVAILABLE_IOS(6_0) {
return UIInterfaceOrientationLandscapeLeft;
}
In terms of the target summary, only portrait mode is "supported".
