Category Concepts Using Portrait to Landscape ViewController Pushing

Considering: View A: Portrait only - View B: Landscape only

I couldn't do it in the navigation controller. Instead what I did was to open a modal view from view A to view B and force a new navigation controller into this view.

This is working for me in iOS5+.

You need to create a category for the navigation controller like this:

UINavigationController+Rotation_IOS.h

#import <UIKit/UIKit.h>

@interface UINavigationController (Rotation_IOS)

- (BOOL)shouldAutorotate;

- (NSUInteger)supportedInterfaceOrientations;

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;

@end

UINavigationController+Rotation_IOS.m

#import "UINavigationController+Rotation_IOS.h"

@implementation UINavigationController (Rotation_IOS)

- (BOOL)shouldAutorotate

{

return [self.topViewController shouldAutorotate];

}

- (NSUInteger)supportedInterfaceOrientations

{

return [self.topViewController supportedInterfaceOrientations];

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{

return [self.topViewController preferredInterfaceOrientationForPresentation];

}

@end

AppDelegate.m

• (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
  {

return UIInterfaceOrientationMaskAll;

}

VIEW A Portrait

- (BOOL)shouldAutorotate

{

return YES;

}

-(NSUInteger)supportedInterfaceOrientations

{

return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{

return UIInterfaceOrientationPortrait;

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);

}

VIEW A to VIEW B while Pushing

SignatureViewController *signatureVC=[[SignatureViewController alloc] initWithNibName:@"SignatureViewController" bundle:Nil];

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:signatureVC];

[self presentViewController:navigationController animated:YES completion:nil];

VIEW B Landscape

#pragma mark -

#pragma mark InterfaceOrientationMethods

- (BOOL)shouldAutorotate

{

return YES;

}

-(NSUInteger)supportedInterfaceOrientations

{

return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;

}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation

{

return UIInterfaceOrientationLandscapeRight;

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

{

return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);

}
