Question

I want all my views to be in Portrait mode. This works except when I push a UINavigationController onto another one. In this case the views inside the secondaryNavigationController will adhere to device orientation instead. Here is how I’m calling the UINavigationControllers.

[secondaryNavigationController setNavigationBarHidden:YES];
[[appDelegate secondaryNavigationController navigationBar] setHidden:YES];
[mainNavigationController presentModalViewController:[appDelegate secondaryNavigationController] animated:YES];

All my views implement this method but it doesn’t seem to help.

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

Here is the full answer that worked for me, building off of iYaniv’s comment and Jacky Boy’s answer.

I took iYaniv’s category and made it a subclass of UINavigationController instead of a category (which is what you should do). Then I replaced all instances of UINavigationController * with myUINavigationController *. Then used Jacky Boy’s snippet in all of my UIViewControllers.

/* myUINavigationController.h */

#import <UIKit/UIKit.h>

@interface myUINavigationController : UINavigationController

@end

and

/* myUINavigationController.m */

#import "myUINavigationController.h"

@interface myUINavigationController ()

@end

@implementation myUINavigationController

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

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

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}

@end
