I have UITableViewController in which on one tab is UINavigationViewController. UINavigationController root view controller is UITableViewController, and when clicked on cell, UIViewController appears which has to be locked in Landscape.
I want every Controller to be locked in Portrait, except the mentioned UIViewController that must be locked in Portrait.
I have tried the following:
CustomTabBarController.m:
#import "CustomTabBarController.h"
#implementation CustomTabBarController
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// You do not need this method if you are not supporting earlier iOS Versions
return [self.selectedViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}
- (BOOL)shouldAutorotate{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations{
return [self.selectedViewController supportedInterfaceOrientations];
}
#end
CustomNavigationController.h:
#import "CustomNavigationController.h"
#implementation CustomNavigationController
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate
{
return YES;
}
#end
And in UIViewController that must be locked in to Landscape, I have put:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight));
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL)shouldAutorotate
{
return YES;
}
But it doesn't work, I can rotate it to Landscape and it will stay locked in Landscape, but I want it to appear automatically in Landscape.
Any suggestions?
I had a big problem in the past with UITabBarController not respecting my supported interface orientations of displayed view controllers.
I solved the problem by sub-classing UITabBarController and capturing whenever an item was selected. I'd then call down to the view controller myself, ask it what the supported orientations are and force a rotation myself if needed. I would also call down to the selected view controller on rotations to set/change my supported orientations.
I implemented the UITabBarDelegate and used didSelectItem to capture tab switches. I'm not sure if there is a better way to do it now.
Try to override method
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
Try with the method to block some orientations for a particular window:
– application:supportedInterfaceOrientationsForWindow:

My app works in both portrait and landscape. But 1 controller should only works in a Portrait.
The problem is that when I am in landscape and push the view controller the new viewcontroller is in landscape as well until I rotate it to portrait. Then it's stuck in portrait as it should be.
Is it possible to always make it appear in portrait? Even if its parent is pushing it in landscape?
All the following code doesn't help
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];
And this code works until and unless i am not pushing from landscape How to force a UIViewController to Portrait orientation in iOS 6
I solved this by adding following lines in ViewDidLoad
UIViewController *c = [[UIViewController alloc]init];
[self presentViewController:c animated:NO completion:nil];
[self dismissViewControllerAnimated:NO completion:nil];
First, you need to create a category:
UINavigationController+Rotation_IOS6.h
#import <UIKit/UIKit.h>
#interface UINavigationController (Rotation_IOS6)
#end
UINavigationController+Rotation_IOS6.m:
#import "UINavigationController+Rotation_IOS6.h"
#implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
#end
Then, you implement these methods in your class that you want to be only landscape:
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
In case you're using a UITabBarController, just replace the UINavigationController for UITabBarController.
This solution worked nice for me after a long search! I was in the same situation as you are now!
EDIT
So, I saw your sample. You need to make some changes.
1 - Create a new class for the UINavigationController category. Name the class UINavigationController+Rotation_IOS6 (.h and .m)
2 - You don't need to implement the method preferredInterfaceOrientationForPresentation. Your category should look like this:
#import "UINavigationController+Rotation_IOS6.h"
#implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
#end
3 - In the class you want to rotate only in landscape, include this in the implementation, exactly like this:
// Rotation methods for iOS 6
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
4 - I would advice to also include the method for autorotation for iOS 5 inside the class you want in landscape:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight;
}
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'm building an app for iOS5 and iOS6. I have this UIViewController inside a UINavigationController and I want it to stay in portrait mode.
The code works for iOS5, but not in iOS6.
// iOS5 rotation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationPortrait)
return YES;
else
return NO;
}
// iOS6 rotation
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
What's the problem here??? On SO I've found lot's of similar questions, but generally the answers are not working for me.
EDIT:
Maybe I was not precise, but I need a SINGLE view controller (the homepage of my app) to stay in portrait mode and not all the app.
First of all, A lot depends on with which controller is your UIViewController embedded in.
Eg, If its inside UINavigationController, then you might need to subclass that UINavigationController to override orientation methods like this.
subclassed UINavigationController (the top viewcontroller of the hierarchy will take control of the orientation.) needs to be set it as self.window.rootViewController.
- (BOOL)shouldAutorotate
{
return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations
{
return self.topViewController.supportedInterfaceOrientations;
}
From iOS 6, it is given that UINavigationController won't ask its UIVIewControllers for orientation support. Hence we would need to subclass it.
MOREOVER
Then, For UIViewControllers, in which you need only PORTRAIT mode, write these functions
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait);
}
For UIViewControllers, which require LANDSCAPE too, change masking to All.
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskAllButUpsideDown);
//OR return (UIInterfaceOrientationMaskAll);
}
Now, if you want to do some changes when Orientation changes, then use this function.
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
}
VERY IMPORTANT
in AppDelegate, write this. THIS IS VERY IMP.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return (UIInterfaceOrientationMaskAll);
}
If you want to provide only Portrait mode for all your viewcontrollers, then apply the portait mask. i.e UIInterfaceOrientationMaskPortrait
Otherwise, if you want that some UIViewControllers stay in Portrait while others support all orientations, then apply an ALL Mask. i.e UIInterfaceOrientationMaskAll
Try out this :
-(BOOL)shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
UIInterfaceOrientationMask orientationMask = UIInterfaceOrientationMaskPortrait;
return orientationMask;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
This should work in order to support the portrait mode only.
I've got an app where I have a UINavigationController subclass as my rootViewController. I've got a UITableViewController that lets the user edit some settings, it should always be in portrait mode. My app also needs to support all other orientations after I push a MoviePlayer component onto the navigation controller.
The UITableViewController subclass has this implementation of supportedInterfaceOrientations:
- (NSUInteger)supportedInterfaceOrientations {
LLog();
return UIInterfaceOrientationMaskPortrait;
}
The logging command tells me that this gets actually called.
The problem is that the return value is not respected, i.e. the screen turns to landscape orientation when I turn the device.
What can I do to make the settings view always show in portrait but allow orientation changes for the video viewer?
More information: my UINavigationController subclass doesn't override shouldAutorotate or supportedInterfaceOrientations. I haven't implemented
- (NSUInteger)application:(UIApplication *)application
supportedInterfaceOrientationsForWindow:(UIWindow *)window
method in my AppDelegate and I have enabled all orientations in the target summary.
I had issue that some ViewControllers in the navigation stack support all the orientations, some only portrait, but UINavigation controller was returning all app supported orientations, this little hack helped me.
#implementation UINavigationController (iOS6OrientationFix)
-(NSUInteger) supportedInterfaceOrientations {
return [self.topViewController supportedInterfaceOrientations];
}
#end
You also need to add:
- (BOOL)shouldAutorotate {
return NO;
}
and set the supported rotations for the root view controller in the app plist file to only portrait.
Category for UINavigationController not working for me. I don't know why. I solve my problem with such category of UIViewController:
#implementation UIViewController (Orientation)
- (BOOL) shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
if ([self isKindOfClass:[PlayerViewController class]])
{
orientations |= UIInterfaceOrientationMaskLandscapeLeft;
orientations |= UIInterfaceOrientationMaskLandscapeRight;
}
return orientations;
}
#end
our app got rejected, becouse the app does not rotate in upside down orientation.
so we have an tabbar App, adding this code to all tabs...
shouldAutorotateToInterfaceOrientation
makes no sense, add this code to a Appdelegate doesn't helps, what we do wrong?
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
UITabbarcontroller is a subclass of UIViewcontroller. To solve you problem just subclass or add a category for you UITabbarcontroller implementing:
#interface UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
#end
#implementation UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
#end
If you want to make the tabbar only rotate to portrait and upside down just use th following code instead
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
Make sure that each UIViewController implements
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
