My app is only for iphone device (both iphone 4 and 5) and built to support only ios 6.
My whole app only supports portrait mode. But there is one view called "ChatView" , which i want to support both landscape and portrait modes.
I have set the required device rotations as follows -
I have also tried following code to support rotation in "ChatView" -
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
But it could not rotate that view.
I have searched a lot for this , but could not be able to find the solution for my issue.
And also in "ChatView" there are some objects like buttons, textfields whose frames are set programmaticaly. So i want to know should i have to set frames of all those objects for landscape mode also?
Please help me.
Thanks.....
Simple but it work very fine. IOS 7.1 and 8
AppDelegate.h
#property () BOOL restrictRotation;
AppDelegate.m
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if(self.restrictRotation)
return UIInterfaceOrientationMaskPortrait;
else
return UIInterfaceOrientationMaskAll;
}
ViewController
-(void) restrictRotation:(BOOL) restriction
{
AppDelegate* appDelegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
appDelegate.restrictRotation = restriction;
}
viewDidLoad
[self restrictRotation:YES]; or NO
I think if you want to support just one viewcontroller rotation, it is not possible since application will follow orientations set by you in .plist file. An alternate you can follow is to support your app for both landscape and portrait, freeze all viewcontrollers rotation to portrait except for chat view.
EDIT
To subclass UINavigationController, create a new file with name e.g. CustomNavigationController and make it subclass of UINavigationController.
.h file
#import <UIKit/UIKit.h>
#interface CustomNavigationController : UINavigationController
#end
.m file
#import "CustomNavigationController.h"
#interface CustomNavigationController ()
#end
#implementation CustomNavigationController
-(BOOL)shouldAutorotate
{
return NO;
}
-(UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
#end
Set the class of your UINavigationController in your main class xib as CustomNavigationController. Hope it helps ypu..
Your view controller will never rotate to any position that is not supported by the app itself. You should enable all possible rotations and then in view controllers that are not supposed to rotate put the following lines
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
In ChatView, it should be:
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
If you need to change your layout after a rotation you should implement the appropriate changes to your subviews in
- (void)viewWillLayoutSubviews
Use self.view.bounds to check the current size of the view, since self.view.frame doesn't change after rotations.
for the specific viewcontroller.m you want to rotate
add this method:
- (BOOL)canAutoRotate
{
return YES;
}
then inside your AppDelegate.m
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
UIViewController *currentViewController = [self topViewController];
if ([currentViewController respondsToSelector:#selector(canAutoRotate)]) {
NSMethodSignature *signature = [currentViewController methodSignatureForSelector:#selector(canAutoRotate)];
NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
[invocation setSelector:#selector(canAutoRotate)];
[invocation setTarget:currentViewController];
[invocation invoke];
BOOL canAutorotate = NO;
[invocation getReturnValue:&canAutorotate];
if (canAutorotate) {
return UIInterfaceOrientationMaskAll;
}
}
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;
}
}
Ted's answer works well with the issue mentioned by Alexander of Norway.
But I figured that issue is not happening the way Alexander explained,
When ViewController B which currently is in landscape (All
orientations enabled) returns back to ViewController A. (Portrait
only) after the user clicks on the back button,
supportedInterfaceOrientationsForWindow doesn't get called and
ViewController A ends up in landscape
Actually when ViewController B which currently is in landscape (All orientations enabled) returns back to ViewController A (Portrait only) after the user clicks on the back button, Appdelegate
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
is getting called. But still root view controller is ViewController B (that rotation enabled view controller), ViewController A is not getting back to portrait orientation, since ViewController B is still returning
-(BOOL)shouldAutorotate{
return YES;
}
So when you press back button return, "shouldAutorotate -> NO" in ViewController B. Then ViewController A will come to Portrait orientation. This is what I did
#property (nonatomic, assign) BOOL canAutoRotate;
#pragma mark - Public methods
- (BOOL)canAutoRotate
{
return _canAutoRotate;
}
#pragma mark - Button actions
- (void)backButtonPressed:(UIButton *)sender {
_canAutoRotate = NO;
(...)
}
#pragma mark - Init
- (id)init{
if(self=[super init]) {
_canAutoRotate = YES;
}
return self;
}
Swift 3 Kosher Version
I've left this here just for a case somebody has the problem.
Apple's documentation for supportedInterfaceOrientations says:
When the user changes the device orientation, the system calls this method on the root view controller or the topmost presented view controller that fills the window. If the view controller supports the new orientation, the window and view controller are rotated to the new orientation. This method is only called if the view controller's shouldAutorotate method returns true.
In few words you have to override supportedInterfaceOrientations in root view controller so that it returns the value for its top child view controller and default value otherwise.
What you should do is checking if app supports all modes (go to Deployment info in targets General settings or Info.plist), find out the class of your root view controller. It can be generic UIViewController, UINavigationController, UITabBarController or some custom class. You can check it out this way:
dump(UIApplication.shared.keyWindow?.rootViewController)
Or any other way you like.
Let it be some CustomNavigationController. So you should override supportedInterfaceOrientations like this:
class CustomNavigationController: UINavigationController {
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return topViewController?.supportedInterfaceOrientations ?? .allButUpsideDown
}
}
In any view controller which should support only portrait orientation for instance override supportedInterfaceOrientations this way:
class ChildViewController: UIViewController {
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return .portrait
}
}
Then don't forget to check if shouldAutorotate of you root view controller and topmost presented view controller already returns true. If not, add this to classes definitions:
override var shouldAutorotate: Bool {
return true
}
Otherwise supportedInterfaceOrientations will nor be called at all.
Here you go!
If you need to fix the opposite problem when only one view controller should support a bunch of orientations and others don't, make this changes to every view controller but this one.
Hope this will help.
I know this questions is very old but It needs an updated answer. The easiest and most correct way to achieve this result is to enable Portrait and Landscape in your app settings. Then add this code to your app delegate:
func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> UIInterfaceOrientationMask {
if let navigationController = self.window?.rootViewController as? UINavigationController {
if navigationController.visibleViewController is INSERTYOURVIEWCONTROLLERHERE {
return UIInterfaceOrientationMask.All
}
else {
return UIInterfaceOrientationMask.Portrait
}
}
return UIInterfaceOrientationMask.Portrait
}
Dont forget to replace "INSERTYOURVIEWCONTROLLERHERE" with your view controller.
I'm not sure about the history of this issue (now = iOS 10 timeframe), but the easiest solution was missing as I posted this in Oct. 2016.
Assuming you want this:
Supporting iOS 7 and newer only (including iOS 10)
Some view controllers should support all orientations, others should support a subset of orientations. Example of what I mean: one view controller should only support portrait, while all others should support all orientations
All view controllers must auto-rotate if they support rotation (meaning, you don't want the code that fixes this issue in your view controllers)
Support adding UINavigationControllers in XIBs/NIBs/Storyboards without having to do anything to them
... then (IMO) the easiest solution is to make a UINavigationControllerDelegate, NOT sub-class UINavigationController (which violates assumption 4 above).
When I solved this, I decided to make my first ViewController a UINavigationControllerDelegate. This view controller sets itself as the navigation controller's delegate, and returns which orientations are allowed. In my case the default is that all orientations are allowed, with portrait preferred, but in one particular case only portrait is allowed. Code below is from Swift 3 / XCode 8:
class iPhoneStartViewController: UIViewController {
var navInterfaceOrientationMask: UIInterfaceOrientationMask?
var navInterfaceOrientationPreferred: UIInterfaceOrientation! = .portrait
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.delegate = self
}
#IBAction func cameraButtonPressed(_ sender: AnyObject) {
if PermissionsHelper.singleton().photosPermissionGranted() == false {
self.navInterfaceOrientationMask = nil // default is: all orientations supported
self.performSegue(withIdentifier: "segueToPhotoAccess", sender: self)
} else {
self.navInterfaceOrientationMask = .portrait // this stops the next view controller from being to rotate away from portrait
self.performSegue(withIdentifier: "segueToCamera", sender: self)
}
}
}
// lock orientation to portrait in certain cases only. Default is: all orientations supported
extension iPhoneStartViewController : UINavigationControllerDelegate {
public func navigationControllerSupportedInterfaceOrientations(_ navigationController: UINavigationController) -> UIInterfaceOrientationMask {
if let mask = self.navInterfaceOrientationMask {
return mask
} else {
return .all
}
}
public func navigationControllerPreferredInterfaceOrientationForPresentation(_ navigationController: UINavigationController) -> UIInterfaceOrientation {
return self.navInterfaceOrientationPreferred
}
}
Based on #iAnum's answer, I've enabled autorotate and UIViewController class detection.
This is because otherwise transitioning into and out of the "special view controller" won't correct to portrait orientation, and you'll be stuck in an unsupported orientation.
I only had one view supporting landscape, so I just hard-coded it in the custom navigation view controller:
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
//Access the current top object.
UIViewController *viewController = [self.viewControllers lastObject];
//Is it one of the landscape supported ones?
if ([viewController isMemberOfClass:[SpecialViewController class]]) {
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
} else
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
//Access the current top object.
UIViewController *viewController = [self.viewControllers lastObject];
//Is it one of the landscape supported ones?
if ([viewController isMemberOfClass:[SpecialViewController class]]) {
return interfaceOrientation;
} else
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
There's a problem popping VCs discussed here https://stackoverflow.com/a/15057537/1277350 where pressing back while in landscape won't even call the orientation methods, so you've got to hack it a bit by showing and dismissing a modal view.
And then just remember that if you want willShowViewController to fire, you need to set self.delegate = self and add the UINavigationControllerDelegate to your custom navigation controller along with the code below.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
UIApplication* application = [UIApplication sharedApplication];
if (application.statusBarOrientation != UIInterfaceOrientationPortrait)
{
UIViewController *c = [[UIViewController alloc]init];
[c.view setBackgroundColor:[UIColor clearColor]];
[navigationController presentViewController:c animated:NO completion:^{
[self dismissViewControllerAnimated:YES completion:^{
}];
}];
}
}
make a subclass of UINavigationController like so:
MyNavigationController.h
#import <UIKit/UIKit.h>
#interface MyNavigationController : UINavigationController
#end
MyNavigationController.m
#import "MyNavigationController.h"
#import "ServicesVC.h"
#implementation MyNavigationController
-(BOOL)shouldAutorotate{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
if ([[self.viewControllers lastObject] isKindOfClass:[ServicesVC class]]) {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
return UIInterfaceOrientationMaskAll;
}
#end
assuming that your viewcontroller is named: ServicesVC
Here is the answer of Alexander (https://stackoverflow.com/posts/25507963/revisions) in Swift:
func application(application: UIApplication, supportedInterfaceOrientationsForWindow window: UIWindow?) -> Int {
var currentViewController: UIViewController? = self.topViewController()
if currentViewController != nil && currentViewController!.canAutoRotate() {
return Int(UIInterfaceOrientationMask.All.rawValue)
}
return Int(UIInterfaceOrientationMask.Portrait.rawValue)
}
func topViewController() -> UIViewController? {
if UIApplication.sharedApplication().keyWindow != nil
{
return self.topViewControllerWithRootViewController(UIApplication.sharedApplication().keyWindow!.rootViewController!)
}
return nil
}
func topViewControllerWithRootViewController(rootViewController: UIViewController?) -> UIViewController? {
if rootViewController == nil {
return nil
}
if rootViewController!.isKindOfClass(UITabBarController) {
var tabBarController: UITabBarController = (rootViewController as? UITabBarController)!
return self.topViewControllerWithRootViewController(tabBarController.selectedViewController)
}
else {
if rootViewController!.isKindOfClass(UINavigationController) {
var navigationController: UINavigationController = (rootViewController as? UINavigationController)!
return self.topViewControllerWithRootViewController(navigationController.visibleViewController)
}
else {
if (rootViewController!.presentedViewController != nil) {
var presentedViewController: UIViewController = rootViewController!.presentedViewController!
return self.topViewControllerWithRootViewController(presentedViewController)
}
else {
return rootViewController
}
}
}
}
In addition, you will need to add the following snippet in AppDelegate.swift:
extension UIViewController {
func canAutoRotate() -> Bool {
return false
}}
And for ViewControllers for which you want to allow all rotations, add this function:
override func canAutoRotate() -> Bool {
return true
}
// paste this method in app deligate class
- (UIInterfaceOrientationMask)application:(UIApplication )application supportedInterfaceOrientationsForWindow:(UIWindow )window
{
if ([self.window.rootViewController.presentedViewController isKindOfClass: [_moviePlayerController class]])
{
if (self.window.rootViewController.presentedViewController)
return UIInterfaceOrientationMaskAll;
else return UIInterfaceOrientationMaskPortrait;
}
else return UIInterfaceOrientationMaskPortrait;
}
I had the same situation. So I subclassed UINavigationController into CustomNavigationController, and inside this CustomNavigationController, I wrote
#define IOS_OLDER_THAN_6 ( [ [ [ UIDevice currentDevice ] systemVersion ] floatValue ] < 6.0 )
#define IOS_NEWER_OR_EQUAL_TO_6 ( [ [ [ UIDevice currentDevice ] systemVersion ] floatValue ] >= 6.0 )
#pragma mark - Rotation
#ifdef IOS_OLDER_THAN_6
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
#endif
#ifdef IOS_NEWER_OR_EQUAL_TO_6
-(BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;;
}
#endif
I used this CustomNavigationController instead of existing NavigationController.
Then inside the view controller that you have to display in LandScape Orientation say LandScapeView, I wrote
#pragma mark - Rotation
#ifdef IOS_OLDER_THAN_6
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight | toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
#endif
#ifdef IOS_NEWER_OR_EQUAL_TO_6
-(BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
#endif
Inside CustomNavigationController, I presented this view controller, not pushed into Navigation Stack. So the LandScapeView appeared in LandScape Orientation.
LandScapeView *graph = [[LandScapeView alloc]init....];
[self presentViewController:graph animated:YES completion:nil];
I did not change anything in the Supported Interface Orientation in Project Settings.
If the App is supporting from IOS7 to IOS9 use this code for Orientation:
#if __IPHONE_OS_VERSION_MAX_ALLOWED < 90000
- (NSUInteger)supportedInterfaceOrientations
#else
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
#endif
{
if([AppDelegate isPad]) return UIInterfaceOrientationMaskAll;
else return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
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;
}
In my application there are three tabs in second tab one viewcontroller in that i want to view only in portrait mode but i m not able to view in that format...so any one have right solution then answer here...
add this methods to your second view controler :
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
Hi I have an Tab Bar based application. When I click on the third tab,the view which opens up has a tableview (AggregateMediaViewController). On didSelect of the rows, I open a video using MPMoviePlayerViewController. I want to set the the orientation of the this video whenever the orientation of the device changes.
I created a subclass of UITabbarController called OrientationTabBarController:
#implementation OrientationTabBarControllerViewController
- (BOOL)shouldAutorotate {
NSLog(#"in shouldAutorotate tabbar is %#", self.viewControllers);
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
In the appDidFifnishLaunching:
[window setRootViewController:tabBarController];
where the tabBarController is a subclass of OrientationTabBarController.
In AggregateMediaViewController, I have the following code:
- (BOOL)shouldAutorotate
{
NSLog(#"in shouldAutorotate of media");
return YES;
}
-(NSInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortraitUpsideDown);
}
But when I run the application, orientation does not work :( Please Help
You need to subclass your parent controller and add rotation methods of your UIViewController. In your case it is UITabBarController. And set it as rootViewController in appDelegate:
[self.window setRootViewController:_myTabBarController];
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;
}
