ios portrait and landscape mode

Question

I have the following scenario:

From appDelegate I do:

firstViewController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
    UINavigationController *firstNavController = [[UINavigationController alloc]initWithRootViewController:firstViewController];

firstViewController - needs to be only in portrait mode

In order to accomplish this I did:

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

- (BOOL)shouldAutorotate
{
   return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
   return UIInterfaceOrientationMaskPortrait;
}

From firstViewController I am pushing another view controller which needs to have both portrait and landscape capabilities.

The secondViewController acts as expected - in portait and landscape mode

I have issues with firstViewController which is displayed in landscape mode too, though I've restricted it to Portrait mode. What am I doing wrong?

Answer 1

Add the UINavigationController Category with following method in your project

#import "UINavigationController+MyNavigation.h"

@implementation UINavigationController (MyNavigation)

-(BOOL)shouldAutorotate
{
    return YES;
}

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

This solved my problem.
