Best way to do this is the create extend UINavigationController and write your orientation function inside the extended class.
Class Declaration:
@interface MyNavigationControllerViewController : UINavigationController
@property(nonatomic, assign) UIInterfaceOrientation orientation;
@property(nonatomic, assign) NSUInteger supportedInterfaceOrientatoin;
@end
Implementation of MyNavigationController
@implementation MyNavigationController
@synthesize supportedInterfaceOrientatoin = _supportedInterfaceOrientatoin;
@synthesize orientation = _orientation;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
_supportedInterfaceOrientatoin = UIInterfaceOrientationMaskLandscape;
_orientation = UIInterfaceOrientationLandscapeLeft;
}
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 YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return _supportedInterfaceOrientatoin;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return self.orientation;
}
@end
and use your extended like MyNavigationController as navigation controller to your rootviewcontroller.
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) ViewController *viewController;
@property (strong, nonatomic) MyNavigationControllerViewController *myNavController;
- (void) reloadAppDelegateRootViewControllerLandscape;
- (void) reloadAppDelegateRootViewController;
@end
So your application delegate didfinishlounchingwithoptions code will be as follow.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
self.myNavController = [[MyNavigationController alloc] initWithRootViewController:self.viewController];
[self.myNavController setNavigationBarHidden:YES];
self.window.rootViewController = self.myNavController;
[self.window makeKeyAndVisible];
return YES;
}
Only way you can provide different orientation for two different view with same navigation controller isto reload the navigation controller itself. So if you add two methods
- (void) reloadAppDelegateRootViewController{
[[[UIApplication sharedApplication].delegate window] setRootViewController:nil];
[(MyNavigationControllerViewController *)self.myNavController setOrientation:UIInterfaceOrientationPortrait];
[(MyNavigationControllerViewController *)self.myNavController setSupportedInterfaceOrientatoin:UIInterfaceOrientationMaskAll];
[[[UIApplication sharedApplication].delegate window] setRootViewController:self.myNavController];
}
- (void) reloadAppDelegateRootViewControllerLandscape{
[[[UIApplication sharedApplication].delegate window] setRootViewController:nil];
[(MyNavigationControllerViewController *)self.myNavController setOrientation:UIInterfaceOrientationLandscapeLeft];
[(MyNavigationControllerViewController *)self.myNavController setSupportedInterfaceOrientatoin:UIInterfaceOrientationMaskLandscape];
[[[UIApplication sharedApplication].delegate window] setRootViewController:self.myNavController];
}
and call these function after pushing and pop views.
Note:- I don't know whether it is a good way or bad way.
