How to force or disable interface orientation for

Question

I have an app with 9-10 screens. I embedded a UINavigationController into my view controller. I have few view controllers which I want set only portrait orientation: it means that rotating the device should not rotate these view controllers to landscape mode. I have tried the following solutions:

first:

   NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
   [[UIDevice currentDevice] setValue:value forKey:@"orientation"];

but screen still rotates to landscape.

Second: I created a custom view controller class as PortraitViewController and added the code below in PortraitViewController.m

@interface PortraitViewController ()
@end

@implementation PortraitViewController
- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    //Here check class name and then return type of orientation
    return UIInterfaceOrientationMaskPortrait;
}
@end

After that I implemented PortraitViewController.h as a base class

#import <UIKit/UIKit.h>
#import "PortraitViewController.h"
@interface Login : PortraitViewController
@end

It does not work at all, still allows view controller to rotate in landscape mode.

Is there any other solution i am using iOS 8 & don't want viewcontroller to rotate in landscape mode?

EDIT: Is it possible to have Landscape orientation only for some view controllers, and force other view controllers orientation to stick to Portrait?

Answer 1

class ViewController: UIViewController {
    override func shouldAutorotate() -> Bool {
        return false
    }
}

Answer 2

Try adding this method along with shouldAutorotate and supportedInterfaceOrientations

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
//Setting the orientation of the view.  I've set it to portrait here.
return UIInterfaceOrientationPortrait;

}

Also you can use this [UIViewController attemptRotationToDeviceOrientation] So that it rotates to the desired new orientation

Answer 3

Your PortraitViewController is ok and I don't know your Storyboard configuration. In your case important thing is you should embedded your target view controller in another new navigation controller, then set it's class to your PortraitViewController and present that navigation modally, like I have done in below image and it's working as expected.

If you want to show animation that will make presentation animation like push animation

Below is mine PortrateNavigation subClass of UINavigationController

PortrateNavigation.h

#import <UIKit/UIKit.h>

@interface PortrateNavigation : UINavigationController

@end

PortrateNavigation.m

#import "PortrateNavigation.h"

@implementation PortrateNavigation

- (void)viewDidLoad  {
    [super viewDidLoad];
}

- (BOOL)shouldAutorotate {
    return YES;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

@end
