I've looked at several answers to questions similar but none of the answer worked. I have an app where I need everything portait except for one photo viewer I have. In the supported orientations section of the targets menu I only have portrait. How do I force my one view to be landscape. It is being pushed onto the stack from a nav controller but I'm using storyboards to control all that.
Since the answer seems to be hidden in the comments of the question and since ArunMak's answer is quite confusing, I'll just offer what I found out:
All I had to do was to add this function to my custom UIViewController subclass for the view:
- (NSUInteger)supportedInterfaceOrientations {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
// iPad: Allow all orientations
return UIInterfaceOrientationMaskAll;
} else {
// iPhone: Allow only landscape
return UIInterfaceOrientationMaskLandscape;
}
}
Note that the project needs to allow all orientations (that is: Portrait, Landscape Left, Landscape Right - but NEVER Upside Down on an iPhone!).
If you want to limit some or most views to Portrait, you need to implement the above method in every of those view controllers (or use a common super class for it and subclass all others from it) — if you limit the Device Orientation in the Info.plist to just Portrait, the app will never even think of going into landscape.
Yes this is possible, you can use this code:
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation {
return orientation==UIInterfaceOrientationMaskLandscape;
}
OR
Try this method in your app delegate
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
if (sglobalorientation isEqualToString:#"AllOrientation"]) {
return UIInterfaceOrientationMaskLandscape;
} else {
return UIInterfaceOrientationMaskAll;
}
}
you need to change the variable value sglobalorientation to that string value AllOrientation before you move to that Landscape view controller
and in your Landscape view controller, use this code in your view will appear
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
DigitalSignatureViewController *digisign = [[DigitalSignatureViewController alloc]init];
[self presentModalViewController:digisign animated:NO];
[self dismissModalViewControllerAnimated:NO];
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return NO;
}
and again when you move to next view controller change the sglobalorientation string value and follow the same step in your next view controller.
Lets try this code:
[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
self.navigationController.view.center = CGPointMake(([UIScreen mainScreen].bounds.size.width/2), [UIScreen mainScreen].bounds.size.height/2);
CGFloat angle = 90 * M_PI / 180;
self.navigationController.view.transform = CGAffineTransformMakeRotation(angle);
self.navigationController.view.bounds = CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.height , [UIScreen mainScreen].bounds.size.width);
The root view controller of navigation controller supports only portrait orientation and other controllers supports all orientation.Now if i am on the root view controller and the DEVICES is in landscape and if i push next view controller that opens in portrait that should open in landscape as it supports all orientation.
Please help me with this.
Using iPhone 4s iOS6.1.3
you can check Device orientation in your first screen after login viewcontroller using bellow code:-
-(void)viewWillAppear:(BOOL)animated
{
[self willRotateToOrientation:[[UIDevice currentDevice] orientation]];
[super viewWillAppear:YES];
}
- (void)willRotateToOrientation:(UIInterfaceOrientation)newOrientation {
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
if (newOrientation == UIInterfaceOrientationLandscapeLeft || newOrientation == UIInterfaceOrientationLandscapeRight) {
//set your landscap View Frame
[self supportedInterfaceOrientations];
}
}
else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
{
if(newOrientation == UIInterfaceOrientationPortrait || newOrientation == UIInterfaceOrientationPortraitUpsideDown){
//set your Potrait View Frame
[self supportedInterfaceOrientations];
}
}
// Handle rotation
}
sor when you load this viewcontroller it check first device oriantation and then load it's related frame
I think this is the issue related to the orientation changes in iOS6. You need to subclass the UINavigationController
Check this
1 . You have to create sub class of UINavigationController. add Following method.. Take one boolean variable to check whether it support for all orientation or not and change its value.
#implementation NavigationControllerViewController
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
AppDelegate *appdelgate=[[UIApplication sharedApplication]delegate];
if (appdelgate.issuppoertAll) {
// for iPhone, you could also return UIInterfaceOrientationMaskAllButUpsideDown
return UIInterfaceOrientationMaskAll;
}
return UIInterfaceOrientationMaskPortrait;
}
#end
2 when you navigate form root view controller to other view controller
use this code , when you want to forcefully change its orientation.i.e lanscape to portrait
obj_viewcontroller = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
[self presentModalViewController:obj_viewcontroller animated:NO];
[self dismissModalViewControllerAnimated:NO];
[self.navigationController pushViewController:obj_viewcontroller animated:NO];
3 In second view controller you have to change boolean variable value
-(void)viewWillAppear:(BOOL)animated
{
appdelgate.issuppoertAll=YES;
}
4 Add this method into all view controller and set orientation as per your need.
- (NSInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
My iPhone app is design to support portrait orientation only, except one view controller that present photos, and support landscape mode as well.
So overall my project support all the orientations, but every view controller (except the photo view controller) implement the method:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
The problem:
In one of my (only portrait) view controller, I'm using UIActivityViewController to let the user choose sharing content through email or SMS.
When the user pick the email option, it automatically shows the ios native email view controller.
If the user now change the device's orientation to landscape, the email view controller also changes to landscape, now if the user tap the cancel/send button, the email controller get dismissed, and now my all app is in landscape!
Is there a way to force the eamil view controller to be in portrait mode only?
I know I can create my own email view controller and subclass UIActivity to show it, but than the UIActivityViewController won't show the default email icon when presented, and I really like it to show it and not some other (must be grey) icon that I'll provide.
You should make another uinavigationcontroller and present uiactivityviewcontroller from there.
In this code _image is a UIImage yo wan to share.
BlankViewController is just place holder viewcontroller you can create in IB you can also make it's view's background colour to clear and do what ever appearance changes you want to do.
__weak CurrentViewController *weakSelf = self ;
UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:#[_image] applicationActivities:nil] ;
UIViewController *viewC = [[UIViewController alloc] initWithNibName:#"BlankViewController" bundle:nil] ;
UINavigationController *navC = [[UINavigationController alloc] initWithRootViewController:viewC] ;
activityViewController.completionHandler = ^(NSString *activityType, BOOL completed)
{
[weakSelf dismissViewControllerAnimated:NO completion: ^ {
; // Your completion handler
}] ;
};
[self presentViewController:navC animated:NO completion: ^ {
[navC presentViewController:activityViewController animated:YES completion: ^ {
;
}] ;
}];
i had similar problems in the app i am currently developing. i ended up overwriting more of the rotation methods to make sure my own viewcontroller stays in portrait.
that's what worked for me (IOS5+):
- (BOOL) shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation (UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
if you are pre ios5 or that's not working for you have a look at:
http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html
hope you get it to work. :)
May be u should try
- (void)viewWillAppear:(BOOL)animated
{
[self shouldAutorotateToInterfaceOrientation: UIInterfaceOrientationLandscapeRight];
[super viewWillAppear:animated];
}
on your view?
Couldn't found a solution to this problem, so I ended up implementing my own email UIActivity subclass...
I'm trying to restrict one view controller which on top of UINavigationController. To do that i've created a UINavigationController subclass and implemented 2 methods
- (BOOL)shouldAutorotate {
return [[self.viewControllers lastObject] shouldAutorotate];}
- (NSUInteger)supportedInterfaceOrientations {
return [[self.viewControllers lastObject] supportedInterfaceOrientations];}
I want the first viewcontroller on top of UINavigationController(which is Root View Controller) should be in portrait mode and the next view controller which i'm pushing from the root view controller should be Landscape mode(ONLY).
So i'm overriding those two methods in both view controllers.
In the root view controller
- (BOOL)shouldAutorotate {
return NO;}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;}
In the next view controller
- (BOOL)shouldAutorotate {
return YES;}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;}
Its working fine but not completely. For the first time when I push the view controller its showing in portrait mode(Not restricting to landscape as I expected) and once I rotate the device/simulator and its working fine and restricting to landscape only.
Can anyone help in this?
Try this out.
Call this one in the viewWillAppear will explicitly tell the device to jump to the portrait orientation.
[[UIDevice currentDevice] performSelector:NSSelectorFromString(#"setOrientation:") withObject:(id)UIInterfaceOrientationPortrait];
I don't think this is the right solution. But if you got no other options, you can use this.
Happy Coding :)
U present new controller :
SecondViewController *objSecondViewController = [[SecondViewController alloc]initWithNibName:#"SecondViewController" bundle:nil];
[self.navigationController presentViewController:objSecondViewController animated:NO completion:^{}];
In new controller :
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
This worked for me. Just try using this :
1) YourApp-Info.plist
Add one more array for Supported interface orientations
Add your required orientation to this dictionary
Refer below screenshot :
2) Project Target
Select the required orientation from Supported Interface Orientations
Refer below screenshot :
UIViewController have the following function. You can implement this in your view controller where you want to restict portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
if(interfaceOrientation == UIInterfaceOrientationPortrait)
return YES;
else
return NO;
}
I gave an app with say 10 view controllers. I use navigation controller to load/unload them.
All but one are in portrait mode. Suppose the 7th VC is in landscape. I need it to be presented in landscape when it gets loaded.
Please suggest a way to force the orientation go from portrait to landscape in IOS 6 (and it will be good to work in IOS 5 as well).
Here is how I was doing it BEFORE IOS 6:
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
UIViewController *c = [[[UIViewController alloc]init] autorelease];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
Presenting and dismissing a modal VC was forcing the app to review its orientation, so shouldAutorotateToInterfaceOrientation was getting called.
What I have have tried in IOS 6:
- (BOOL)shouldAutorotate{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationLandscapeLeft;
}
On load, the controller keeps staying in portrait. After rotating the device, the orientation changes just ok. But I need to make the controller to rotate automatically to landscape on load, thus the user will have to rotate the device to see the data correctly.
Another problem: after rotating the device back to portrait, the orientation goes to portrait, although I have specified in supportedInterfaceOrientations only UIInterfaceOrientationMaskLandscape. Why it happens?
Also, NONE of above 3 methods are getting called.
Some (useful) data:
In my plist file I have specified 3 orientations - all but upside down.
The project was started in Xcode 4.3 IOS 5. All classes including xibs were created before Xcode 4.5 IOS 6, now I use the last version.
In plist file the status bar is set to visible.
In xib file (the one I want to be in landscape) the status bar is "None", the orientation is set to landscape.
Any help is appreciated. Thanks.
Ok, folks, I will post my solution.
What I have:
A view based application, with several view controllers. (It was navigation based, but I had to make it view based, due to orientation issues).
All view controllers are portrait, except one - landscapeLeft.
Tasks:
One of my view controllers must automatically rotate to landscape, no matter how the user holds the device. All other controllers must be portrait, and after leaving the landscape controller, the app must force rotate to portrait, no matter, again, how the user holds the device.
This must work as on IOS 6.x as on IOS 5.x
Go!
(Update Removed the macros suggested by #Ivan Vučica)
In all your PORTRAIT view controllers override autorotation methods like this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
-(BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
You can see the 2 approaches: one for IOS 5 and another For IOS 6.
The same for your LANDSCAPE view controller, with some additions and changes:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
[image_signature setImage:[self resizeImage:image_signature.image]];
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
-(BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
[image_signature setImage:[self resizeImage:image_signature.image]];
return UIInterfaceOrientationMaskLandscapeLeft;
}
ATTENTION: to force autorotation in IOS 5 you should add this:
- (void)viewDidLoad{
[super viewDidLoad];
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 6.0)
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationLandscapeLeft animated:NO];
}
Analogically, after you leave the LANDSCAPE controller, whatever controller you load, you should force again autorotation for IOS 5, but now you will use UIDeviceOrientationPortrait, as you go to a PORTRAIT controller:
- (void)viewDidLoad{
[super viewDidLoad];
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 6.0)
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];
}
Now the last thing (and it's a bit weird) - you have to change the way you switch from a controller to another, depending on the IOS:
Make an NSObject class "Schalter" ("Switch" from German).
In Schalter.h say:
#import <Foundation/Foundation.h>
#interface Schalter : NSObject
+ (void)loadController:(UIViewController*)VControllerToLoad andRelease:(UIViewController*)VControllerToRelease;
#end
In Schalter.m say:
#import "Schalter.h"
#import "AppDelegate.h"
#implementation Schalter
+ (void)loadController:(UIViewController*)VControllerToLoad andRelease:(UIViewController*)VControllerToRelease{
//adjust the frame of the new controller
CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];
CGRect windowFrame = [[UIScreen mainScreen] bounds];
CGRect firstViewFrame = CGRectMake(statusBarFrame.origin.x, statusBarFrame.size.height, windowFrame.size.width, windowFrame.size.height - statusBarFrame.size.height);
VControllerToLoad.view.frame = firstViewFrame;
//check version and go
if (IOS_OLDER_THAN_6)
[((AppDelegate*)[UIApplication sharedApplication].delegate).window addSubview:VControllerToLoad.view];
else
[((AppDelegate*)[UIApplication sharedApplication].delegate).window setRootViewController:VControllerToLoad];
//kill the previous view controller
[VControllerToRelease.view removeFromSuperview];
}
#end
NOW, this is the way you use Schalter ( suppose you go from Warehouse controller to Products controller ) :
#import "Warehouse.h"
#import "Products.h"
#implementation Warehouse
Products *instance_to_products;
- (void)goToProducts{
instance_to_products = [[Products alloc] init];
[Schalter loadController:instance_to_products andRelease:self];
}
bla-bla-bla your methods
#end
Of course you must release instance_to_products object:
- (void)dealloc{
[instance_to_products release];
[super dealloc];
}
Well, this is it. Don't hesitate to downvote, I don't care. This is for the ones who are looking for solutions, not for reputation.
Cheers!

This should work, it's similar to the pre-iOS 6 version, but with a UINavigationController:
UIViewController *portraitViewController = [[UIViewController alloc] init];
UINavigationController* nc = [[UINavigationController alloc] initWithRootViewController:portraitViewController];
[self.navigationController presentModalViewController:nc animated:NO];
[self.navigationController dismissModalViewControllerAnimated:NO];
I'm calling this before I'm pushing the next UIViewController. It will force the next pushed UIViewController to be displayed in Portrait mode even if the current UIViewController is in Landscape (should work for Portrait to Landscape too). Works on iOS 4+5+6 for me.
I think that best solution is to stick to official apple documentation. So according to that I use following methods and everything is working very well on iOS 5 and 6.
In my VC I override following methods:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
Methods for iOS 6, first method returns supported orientation mask (as their name indicate)
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
second one thats tells your VC which is preferred interface orientation when VC is going to be displayed.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
Just change Portrait for orientation that you want ;)
This solution is working smooth, I don't like the idea of creating macros and other stuff, that goes around this simple solution.
Hope this help...
I had the same problem, 27 views in my application from which 26 in portrait and only one in all orientations ( an image viewer :) ).
Adding the macro on every class and replace the navigation wasn't a solution I was comfortable with...
So, i wanted to keep the UINavigationController mechanics in my app and not replace this with other code.
What to do:
#1 In the application delegate in method didFinishLaunchingWithOptions
if ([[UIDevice currentDevice].systemVersion floatValue] < 6.0)
{
// how the view was configured before IOS6
[self.window addSubview: navigationController.view];
[self.window makeKeyAndVisible];
}
else
{
// this is the code that will start the interface to rotate once again
[self.window setRootViewController: self.navigationController];
}
#2
Because the navigationController will just responde with YES for autorotation we need to add some limitations:
Extend the UINavicationController -> YourNavigationController and link it in the Interface Builder.
#3 Override the "anoying new methods" from navigation controller.
Since this class is custom only for this application it can take responsibility
for it's controllers and respond in their place.
-(BOOL)shouldAutorotate {
if ([self.viewControllers firstObject] == YourObject)
{
return YES;
}
return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
if ([self.viewControllers firstObject] == YourObject)
{
return UIINterfaceOrientationMaskLandscape;
}
return UIInterfaceOrientationMaskPortrait;
}
I hope this will help you,
From the iOS 6 Release Notes:
Now, iOS containers (such as UINavigationController) do not consult their children to determine whether they should autorotate.
Does your rootViewController pass the shouldAutoRotate message down the ViewController hierarchy to your VC?
I used the same method as OP pre-ios6 (present and dismiss a modal VC) to show a single view controller in landscape mode (all others in portrait). It broke in ios6 with the landscape VC showing in portrait.
To fix it, I just added the preferredInterfaceOrientationForPresentation method in the landscape VC. Seems to work fine for os 5 and os 6 now.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
Hey guys after tryng a lot of different possible solutions with no success i came out with the following solution hope it helps!.
I prepared a recipe :).
Problem:
you need change orientation of viewcontrollers using navigationcontroller in ios 6.
Solution:
step 1. one initial UIviewcontroler to trigger modal segues to landscape and
portrait UInavigationControllers as picture shows....
more deeply in UIViewController1 we need 2 segues actions according to global variable at Appdelegate....
-(void)viewDidAppear:(BOOL)animated{
if([globalDelegate changeOrientation]==0){
[self performSegueWithIdentifier:#"p" sender:self];
}
else{
[self performSegueWithIdentifier:#"l" sender:self];
}
}
also we need a way back to portrait &| landscape....
- (IBAction)dimis:(id)sender {
[globalDelegate setChangeOrientation:0];
[self dismissViewControllerAnimated:NO completion:nil];
}
step 2. the first Pushed UiViewControllers at each NavigationController goes
with...
-(NSUInteger)supportedInterfaceOrientations{
return [self.navigationController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate{
return YES;
}
step 3. We overwrite supportedInterfaceOrientations method at subclass of UInavigationController....
in your customNavigationController we have .....
-(NSUInteger)supportedInterfaceOrientations{
if([self.visibleViewController isKindOfClass:[ViewController2 class]]){
return UIInterfaceOrientationMaskPortrait;
}
else{
return UIInterfaceOrientationMaskLandscape;
}
}
step 4. At storyboard or by code, set wantsFullScreenLayout flag to yes, to both portrait and landscape uinavigationcontrollers.
Try segueing to a UINavigationController which uses a category or is subclassed to specify the desired orientation, then segue to the desired VC. Read more here.
As an alternative you can do the same using blocks:
UIViewController *viewController = [[UIViewController alloc] init];
viewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:viewController animated:NO completion:^{
[self dismissViewControllerAnimated:NO completion:nil];
}];
Also, call it before pushing the new view.
Go to you Info.plist file and make the change
I had the same problem. If you want to force a particular view controller to appear in landscape, do it right before you push it into the navigation stack.
UIInterfaceOrientation currentOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if (currentOrientation == UIInterfaceOrientationPortrait ||
currentOrientation == UIInterfaceOrientationPortraitUpsideDown)
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
UIViewController *vc = [[UIViewController alloc] init];
[self.navigationController pushViewController:vc animated:YES];
[vc release];
I solved it by subclassing UINavigationController and overriding the supportedInterfaceOrientations of the navigation Controller as follow:
- (NSUInteger)supportedInterfaceOrientations
{
return [[self topViewController] supportedInterfaceOrientations];
}
All the controllers implemented supportedInterfaceOrientations with their desired orientations.
I have used the following solution. In the one view controller that has a different orientation than all the others, I added an orientation check in the prepareForSegue method. If the destination view controller needs a different interface orientation than the current one displayed, then a message is sent that forces the interface to rotate during the seque.
#import <objc/message.h>
...
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if(UIDeviceOrientationIsLandscape(self.interfaceOrientation))
{
UIInterfaceOrientation destinationOrientation;
if ([[segue destinationViewController] isKindOfClass:[UINavigationController class]])
{
UINavigationController *navController = (UINavigationController *)[segue destinationViewController];
destinationOrientation = [navController.topViewController preferredInterfaceOrientationForPresentation];
} else
{
destinationOrientation = [[segue destinationViewController] preferredInterfaceOrientationForPresentation];
}
if ( destinationOrientation == UIInterfaceOrientationPortrait )
{
if ([[UIDevice currentDevice] respondsToSelector:#selector(setOrientation:)])
{
objc_msgSend([UIDevice currentDevice], #selector(setOrientation:), UIInterfaceOrientationPortrait );
}
}
}
}
