Rotation behaving differently on iOS6

Question

I did an App which is tab-based. Nothing needs to be on landscape mode but a couple of views. It worked OK on iOS5 and I was pretty happy with the result. However with iOS6

Answer 1

This is what works for me.

I created a new subclass of UINavigationController, and added shouldAutorotate and supportedInterfaceOrientation methods:

#import "MyNavigationController.h"

@interface MyNavigationController ()

@end

@implementation MyNavigationController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

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

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (BOOL)shouldAutorotate {
    return [self.visibleViewController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations {
    return [self.visibleViewController supportedInterfaceOrientations];
}

@end

Then add this to your delegate

UINavigationController *nvc = [[MyNavigationController alloc] initWithRootViewController:_viewController];
nvc.navigationBarHidden = NO; // YES if you want to hide the navigationBar
self.window.rootViewController = nvc;
[_window addSubview:nvc.view];
[_window makeKeyAndVisible];

Now you can add this to the views you want to rotate in all orientations

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

-(BOOL)shouldAutorotate
{
    return YES;
}

Or add this to the views you only want to go portrait and portraitUpsideDown

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

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown ;
}

- (BOOL)shouldAutorotate
{
    return YES;
}
