I'm trying to keep UITableViewcontroller in Portrait orientation. Hence, I don't want to rotate to Landscape mode. I added below method. But it didn't help, notice I'm using iOS 8:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if(interfaceOrientation== UIInterfaceOrientationPortrait)
{
return YES;
}else
{
return NO;
}
}
Notice: I'm calling the UITableView through UINavigationController
UINavigationController *navigationController = [[UINavigationController alloc]
initWithRootViewController:svc];
// configure the new view controller explicitly here.
[self presentViewController:navigationController animated:YES completion: nil];
shouldAutorotateToInterfaceOrientation: has been deprecated since iOS 6.0. You should be using supportedInterfaceOrientations and shouldAutorotate.
Here's how you do it:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotate
{
return NO;
}
EDIT - for UINavigationController
This is one possible way to do it:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
if ([self.visibleViewController isKindOfClass:[UITableViewController class]])
return UIInterfaceOrientationPortrait;
else
return [super preferredInterfaceOrientationForPresentation];
}
- (NSUInteger)supportedInterfaceOrientations
{
if ([self.visibleViewController isKindOfClass:[UITableViewController class]])
return UIInterfaceOrientationMaskPortrait;
else
return [super supportedInterfaceOrientations];
}
- (BOOL)shouldAutorotate
{
if ([self.visibleViewController isKindOfClass:[UITableViewController class]])
return NO;
else
return [super shouldAutorotate];
}
Note that you can't force the device orientation, so if the app is in landscape and you then push the table view controller, it will still be in landscape. There are a number of ways to handle this:
Block the user from opening the table view controller by displaying an alert asking them to rotate the device first.
Hide the table view and show a label with a message (or some other indicator) to tell the user to rotate their device.
Handle both orientations.
shouldAutorotateToInterfaceOrientation: is depricated. Instead, use:
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotate
{
return NO;
}

I want to lock single viewcontroller in iPhone and iPad.
This below code is working perfectly in iPhone 4,5,6 iPad, iPad 2 ,iPad retina.
But not working in iPad pro.
#implementation UINavigationController (Orientation)
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate
{
return YES;
}
#end
This above code is written in my view controller which view controller i do not want to rotate.
Write this below code in view controller, which view controller u want to lock in portrait mode
#implementation UINavigationController (Orientation)
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate
{
return YES;
}
#end
#pragma mark Orientation
-(BOOL)shouldAutorotate
{
[super shouldAutorotate];
return NO;
}
-(NSUInteger) supportedInterfaceOrientations {
[super supportedInterfaceOrientations];
// Return a bitmask of supported orientations. If you need more,
// use bitwise or (see the commented return).
return UIInterfaceOrientationMaskPortrait;
// return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {
[super preferredInterfaceOrientationForPresentation];
// Return the orientation you'd prefer - this is what it launches to. The
// user can still rotate. You don't have to implement this method, in which
// case it launches in the current orientation
return UIInterfaceOrientationPortrait;
}
And now do this below changes in your plist file
Write this in your view controller which you don't want to rotate
This will prevent any rotation.
The view controller class you don't want to rotate should have this.
- (BOOL)shouldAutorotate
{
return NO;
}
The containing navigation controller class should have this.
- (BOOL)shouldAutorotate
{
return [self.topViewController shouldAutoRotate];
}
This will only rotate to portrait
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
I have a problem with my app. I cannot lock the orientation of my app. All I need to do is to lock one view controller to landscape mode and the rest are portrait.
This is hierarchy of my app.
*Navigation Controller
*TabBarController
*ViewControllers
You only have to return NO from shouldAutorotate and the landscape orientation from supportedInterfaceOrientation in the one you want to be in landscape.
On the other, return NO too from shouldAutorotate method and portrait orientations mask from supportedInterfaceOrientation.
In all the viewControllers :
-(BOOL)shouldAutorotate {
return NO;
}
In the one you want in landscape :
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationLandscapeLeft;
}
In the controllers you want in portrait :
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;
}
Use below 2 this methods to lock device orientation to landscape.
- (NSUInteger)supportedInterfaceOrientations{
[super supportedInterfaceOrientations];
return (UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight);
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (interfaceOrientation==UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight)
{
return YES;
}
// Return YES for supported orientations
return NO;
}
With NavigationController
-(BOOL)shouldAutorotate
-(NSUInteger)supportedInterfaceOrientations
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
these method are never called , if you use 'show segue(push)'.
change segue 'showDetail' instead 'show'
I have embedded a UIViewController in a UINavigationController. The orientation of the view of this controller is set to Portait. When I push a new view on this UIViewController, which is landscape only, the new view is being shown portrait as well, instead of it's orientation landscape.
I have tried to subclass the UINavigationController and added the following methods like this:
- (BOOL)shouldAutorotate {
return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations {
return self.topViewController.supportedInterfaceOrientations;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return self.topViewController.preferredInterfaceOrientationForPresentation;
}
In the rootViewController (LoginViewController) I did this:
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotate
{
return YES;
}
In the pushViewController (A custom ViewController) I did this:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL)shouldAutorotate {
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft;
}
I'm using a storyboard and a push segue between them. I know that the problem lies in the push segue which leads to an taking over of the orientation of the topviewcontroller which is portrait and the pushViewController is landscape. Does anyboy know workarounds?
Any help is thankfully appreciated. Else I should drop the navVC and perform a modal segue.

Try this code :
In AppDelegate.m class write below code.
#pragma mark Orientation Code
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
NSUInteger orientations = UIInterfaceOrientationMaskAll;
if (self.window.rootViewController) {
UIViewController* presented = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presented supportedInterfaceOrientations];
}
return orientations;
}
And next if you don't want orientation of the particular class for example
Stop orientation viewController.m
#pragma mark Orientation
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotate
{
return NO;
}
final thing to change project device orientation of project Target.
Ex : Project TARGETS --> Device Orientation -- > select All (Portrait, UpSide Down, Landscape Left, Landscape Right)
I have iPhone application that supports only Portrait orientation. I want to add to my project view controller that will support only Landscape orientation? Is it possible? If yes how could I achieve that?
I have tried to crate category file like this:
#implementation UINavigationController (Rotation_IOS7)
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
If I do this I get this error:
Terminating app due to uncaught exception UIApplicationInvalidInterfaceOrientation, reason: Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES
I've tried this and it works: http://www.sebastianborggrewe.de/only-make-one-single-view-controller-rotate/
First, add these code to your AppDelegat class.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
// Get topmost/visible view controller
UIViewController *currentViewController = [self topViewController];
// Check whether it implements a dummy methods called canRotate
if ([currentViewController respondsToSelector:#selector(canRotate)]) {
// Unlock landscape view orientations for this view controller
return UIInterfaceOrientationMaskAllButUpsideDown;
}
// Only allow portrait (standard behaviour)
return UIInterfaceOrientationMaskPortrait;
}
- (UIViewController*)topViewController {
return [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
}
- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)rootViewController {
if ([rootViewController isKindOfClass:[UITabBarController class]]) {
UITabBarController* tabBarController = (UITabBarController*)rootViewController;
return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];
} else if ([rootViewController isKindOfClass:[UINavigationController class]]) {
UINavigationController* navigationController = (UINavigationController*)rootViewController;
return [self topViewControllerWithRootViewController:navigationController.visibleViewController];
} else if (rootViewController.presentedViewController) {
UIViewController* presentedViewController = rootViewController.presentedViewController;
return [self topViewControllerWithRootViewController:presentedViewController];
} else {
return rootViewController;
}
}
Then, in your landscape view controller, add this method
- (void)canRotate { }
I have search through numerous topics and finally found a working solution.
In my example, I have two VC's:
A -> VC that is embedded inside Nav. Controller and should only support Portrait view.
B -> VC that is not embedded inside a VC and should support Landscape only.
I would like to go from view A to view B (by pressing a button) and back to view then A with the specific orientations still correct.
I. Create a Category for UINavigationController and write the following in its .m file: (the code will be automatically called)
- (NSUInteger)supportedInterfaceOrientations
{
NSLog(#"supportedInterfaceOrientations = %d ", [self.topViewController supportedInterfaceOrientations]);
return [self.topViewController supportedInterfaceOrientations];
}
- (BOOL)shouldAutorotate
{
return self.topViewController.shouldAutorotate;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// You do not need this method if you are not supporting earlier iOS Versions
return [self.topViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}
II.
Create a modal segue between A and B and after that between another one between B and A.
III. Write down in each of the View Controllers .m files the following:
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
OR
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
After adding this code. You will be able to change orientation for the single view B.
Edit:
create a category in .h and then implement those methods
use these methods in the view controller where you want to support landscape
#implementation UINavigationController (Rotation_IOS7)
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
I have parent view controller and another modal view controller.
I presented modal view controller within parent's context:
readingViewController * reading_view_controller = [[readingViewController alloc] initWithNibName:#"readingViewController" bundle:nil];
[self setModalPresentationStyle:UIModalPresentationCurrentContext];
[self presentModalViewController:reading_view_controller animated:YES];
Parent viewController will not orient Landscape; so, i added these methods in the parent viewController:
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortraitUpsideDown|UIInterfaceOrientationMaskPortrait;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
The presented viewController (modally presented) should orient to all possible orientations; so, i added these methods:
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskAll;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return YES;
}
But, because I assumed (UIModalPresentationCurrentContext), the presented viewController doesn't orient in IOS 6.0 while it is working as expected in IOS 5.0
How to solve this problem please?
If you have a tab-based app, then first add some code in app delegate and also self.window.rootviewcontroller-self.tabbarcontroller.
#implementation UITabBarController (SK8FASTR2App)
-(BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
// your custom logic for rotation of selected tab
if (self.selectedIndex==3){
return UIInterfaceOrientationMaskPortrait;
}
else {
UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskPortraitUpsideDown|UIInterfaceOrientationLandscapeLeft|UIInterfaceOrientationLandscapeRight;
return UIInterfaceOrientationMaskAll;
}
}
#end
before
#implementation AppDelegate
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
return UIInterfaceOrientationMaskAll;
}
Change orientation on that class
-(BOOL)shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
You should implement
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;
eg :-
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationMaskAll;
}
