Objective C only portrait orientation in a viewcontroller

Question

I need to have a ViewController only in portrait orientation. I tried use this code but it didn't work:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

-(BOOL) shouldAutorotate {
    return NO;
}

I tried it too:

AppDelegate.m:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    NSLog(@"Interface orientations %@", window);
    if(!enablePortrait)
        return UIInterfaceOrientationMaskLandscape|UIInterfaceOrientationMaskPortrait;
    return UIInterfaceOrientationMaskPortrait;
}

AudioViewController.m

- (void) viewWillAppear:(BOOL)animated{

    [super viewWillAppear:YES];

    ((AppDelegate *)[[UIApplication sharedApplication] delegate]).enablePortrait= YES;
}

it works if initially the iPad was in portrait mode. But if the iPad was in landscape mode, when I go back to the previous viewController (AudioViewController.m) the viewController stays in landscape too.

I tried it too i viewWillAppear.m but no effect:

[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];

Please help me!

Thank you for advance.

EDIT

PROVISIONAL SOLUTION:

Finally I do this: (It works for me, but I hope find a better solution)

- (void) viewWillAppear:(BOOL)animated{

    [super viewWillAppear:YES];

    ((AppDelegate *)[[UIApplication sharedApplication] delegate]).enablePortrait= YES;
    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];

    UINavigationController* nc = [[UINavigationController alloc] init];
    [self.navigationController presentViewController:nc animated:NO completion:^{
    }];
    [self.navigationController dismissViewControllerAnimated:YES completion:^{
    }];
}

Regarding the content of the link, I don't understand where I have to push this code: LandscapeViewController * viewController = [[[LandscapeViewController ViewController alloc] init] autorelease]; UINib * nib = [UINib nibWithNibName:@"NavigationController" bundle:nil]; NavigationController *navController = [[nib instantiateWithOwner:nil options:nil] objectAtIndex:0]; [navController initWithRootViewController:viewController]; [self presentViewController:navController animated:YES completion:^{ // completion }]; — amurcia, Jan 15 '14 at 09:34
Have I to create a new ViewController named LandscapeViewController? — amurcia, Jan 15 '14 at 09:35
No. I think that should be a previous ViewController (the one you're pushing from) — Andrey Gordeev, Jan 15 '14 at 10:15

use this inside the APPDelegate class for make viewcontroller always in portrait:- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window { return UIInterfaceOrientationMaskPortrait; }

I tried this, and the error was: `*** Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES'` when I push the landscape viewController – amurcia Jan 15 '14 at 10:49
you just need to implement this method in AppDelegate.m and remove any other orientation method from view controller...if it's not working then please send me your block of code. – Shubham Jan 15 '14 at 11:05
**AppDelegate.m** `- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window { return UIInterfaceOrientationMaskPortrait; }` **AudioViewController.m** `- (void) viewWillAppear:(BOOL)animated{ [super viewWillAppear:YES]; }` And I delete other functions related with orientation... – amurcia Jan 15 '14 at 11:10
create new demo application and use above function only in AppDelegate.m and after that you can use this to according to your requirement. – Shubham Jan 15 '14 at 11:20

-(BOOL)shouldAutorotate{
    if (self.interfaceOrientation == UIInterfaceOrientationPortrait) {
        return YES;
    }
    else {
        return NO;
    }
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

And please make your supportedInterfaceOrientations method same. Let me know if that helps.. :)

Did you changed supportedInterfaceOrientations? – Rashad Jan 15 '14 at 08:55
Sorry, I'll change it – amurcia Jan 15 '14 at 08:58
I can't change supportedInterfaceOrientation because I received a UIWindow *window not a ViewController to get de interfaceOrientation... – amurcia Jan 15 '14 at 09:07
Another thing, do you want to make the full app in potrait mode? – Rashad Jan 15 '14 at 09:14
No, I only want a viewController in portrait mode. Others viewControllers in landscape. – amurcia Jan 15 '14 at 09:18
