I have a UITableViewController that works in both portrait and landscape. From this controller I push another view controller on to the navigation controller. This new viewController is portrait only.
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?
Update:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
In viewWillAppear: after statusbar orientation change put this:
//present/dismiss viewcontroller in order to activate rotating.
UIViewController *mVC = [[[UIViewController alloc] init] autorelease];
[self presentModalViewController:mVC animated:NO];
[self dismissModalViewControllerAnimated:NO];
Hopefully it will help!
P.S.Tested on sdk 3.2.5 ios 5.0.1.
In your viewWillAppear: use the following code:
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];

I have this setup to support only landscape orientation in most of my viewcontrollers
My app delegate has this piece of code:
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
NSUInteger orientations = UIInterfaceOrientationMaskLandscape;
if (self.window.rootViewController) {
UIViewController * pressented = [[((UINavigationController *)self.window.rootViewController) viewControllers] lastObject];
orientations =[pressented supportedInterfaceOrientations];
}
return orientations;
}
And in most viewcontrollers this:
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
My problem comes when I push THIS controller (the one I would like to rotate):
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskALL;
}
It rotates perfectly BUT when I pop the viewcontroller (tap the back button of the navigation bar) with the orientation in portrait, the presenting viewcontroller also sets it's orientation to Portrait.
How can I make the presenting viewcontroller stays locked on landscape, or force the problematic controller to rotate back to landscape before popping.
Add this to your portrait view controller:
-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
UIViewController* dummyController = [[UIViewController alloc] init];
[self presentViewController:dummyController animated:NO completion:^{
[self dismissViewControllerAnimated:NO completion:nil];
}];
}
I know it's a hack, but it works. Anyone knows a better solution?
I have a master view controller that's inside a UINavigationController. In that master view controller, I have a button that pushes a detail view controller that has a UIWebView inside of it. I want this detail view controller to be on landscape mode when it's loaded. Going back to the master view controller, it forcibly goes back again to portrait mode. I'm running iOS 6 on this.
I have seen the other similar questions but it's not working on my end. I have created a LandscapeViewController that's a subclass of UIViewController where I have written these methods:
#pragma mark - Orientation Methods
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
- (BOOL)shouldAutorotate
{
return YES;
}
This is my code when I push the detail view controller:
DetailViewController *detailVC = [[DetailViewController alloc]
initWithNibName:#"DetailViewController"
bundle:nil];
[self.navigationController pushViewController:detailVC
animated:YES];
I'm thinking on where to subclass my LandscapeViewController on the code above to make it work or on how to properly subclass and push my detail view controller. I can also present my detail view controller modally if it's not possible for the navigation controller to push my detail view controller from portrait to landscape. Where am I doing it wrong?
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_IOS6.h
#import <UIKit/UIKit.h>
#interface UINavigationController (Rotation_IOS6)
- (BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;
#end
UINavigationController+Rotation_IOS6.h
#import "UINavigationController+Rotation_IOS6.h"
#implementation UINavigationController (Rotation_IOS6)
- (BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.topViewController preferredInterfaceOrientationForPresentation];
}
#end
In AppDelegate.m add:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskAll;
}
Then in View A:
- (BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
also in View A to open View B do this:
ViewB *vc = [[ViewB alloc] initWithNibName:#"ViewB" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:vc];
[self presentViewController:navigationController animated:YES completion:nil];
And, finally, in View B
- (BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
They kinda screwed the pooch in iOS 6 with regard to this. Here's what I've figured out so far:
First off, Apple added the "Supported Interface Orientations" buttons with Xcode 4.5. This corresponds to the "Supported interface orientations" attribute in _info.plist. These buttons must be toggled to the correct choices before any of the rest will work. (If the buttons seem to refuse to toggle it's likely because the info.plist is locked by CVS or some other process.)
Next, the property .window.rootViewController must be set, and must point to the "bottom" view controller in the stack. Generally this will be either a navigation controller or a tab controller.
If the desire is to disable all rotation, this can be done using the buttons, or one can implement, in the "bottom" view controller, the "shouldAutorotate" method and have it return NO. (If the method is omitted then the default is YES.)
In spite of having autorotation disabled with shouldAutorotate, if there is a MPMoviePlayerViewController being displayed, that will autorotate. Only toggling the supported interface orientation buttons appears to prevent this.
If one wants to conditionally autorotate other view controllers it gets messier. Basically, your "bottom" view controller must implement the supportedInterfaceOrientations method and return, based on the current topViewController, the appropriate bit mask. This can be done with a routine that queries the topViewController's old "shouldAutorotateToInterfaceOrientation" method, but it's a bit ugly. And even though this scheme doesn't require modifying the rotating view controller's code, you DO need to modify the VC just "below" the rotated one to implement "supportedInterfaceOrientation", or else that view will be rotated on return. (At least this is a simple copy/paste.) No one seems to have come up with a better, more general scheme, though.
All view controllers in my app are working only in portrait orientation except one which can be portrait or landscape oriented.
I have some usage scenario like following:
I push controller which works in both orientations to UITabBarController
User change orientation from portait to landscape
User press "back button"
After these actions application remains in landscape orientation and does not change it automatically to portrait.
I control view controller orientation using supportedInterfaceOrientations (I use iOS 6.0). What I do wrong? How can I get correct behaviour when application automatically change orientation to allowed when user press back button? Thank you for answer!
In iOS 6 (and possibly earlier), if a view controller is offscreen when the device rotates, it does not get any notification. Nor does it get sent willAnimateRotationToInterfaceOrientation:duration: when it becomes the top view controller.
You need to keep track of the current orientation of the view controller and check the device orientation in viewWillAppear:. If they are different, you can use willAnimateRotationToInterfaceOrientation:duration: to set it correctly.
Since this is something you are likely to do a lot, you may want to create a generic superclass that your view controllers inherit from.
A typical solutions is:
#implementation MyHandlesOffscreenRotationController
{
BOOL isShowingPortrait;
}
- (void) viewDidLoad
{
[super viewDidLoad];
isShowingPortrait = UIInterfaceOrientationIsPortrait(
[[UIApplication sharedApplication] statusBarOrientation]);
}
- (void) viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
BOOL currIsPortrait = UIInterfaceOrientationIsPortrait(
[[UIApplication sharedApplication] statusBarOrientation]);
if ((isShowingPortrait && !currIsPortrait) ||
(!isShowingPortrait && currIsPortrait)) {
[self willAnimateRotationToInterfaceOrientation:
[[UIApplication sharedApplication] statusBarOrientation]
duration:0.0f];
}
}
#end
Just override -(BOOL)shouldAutoRotate and - (NSUInteger)supportedInterfaceOrientations inside a UINavigationController category, then ViewController will force rotate to its supported orientation after pop from other ViewController.
#implementation UINavigationController (Rotate)
- (BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
#end
iOS 9 and above
At the time of pop just write the below-mentioned code in your viewWillAppear method.
[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger: UIInterfaceOrientationPortrait]forKey:#"orientation"];
With this, your view will appear in portrait mode.
P.L. has a nice solution in this topic: Present and instantly dismiss an empty modal view controller which allows only portrait | landscape
How to change the device orientation programmatically in iOS 6
I'm in a real mess right now . I used apples sample code which does this :
Create a portrait view controller and a landscape view controller
Potrait event controller then registers for device orientation changed notifications
When device is rotated it presents a modal view controller for the landscape view or dismisses the landscape view if it is rotated back to portrait .
Everythings working as it should except for a little problem ....
Now to my problem . I used this to launch a rotatable view controller from a table view . It can be rotated and works fine . But if I initially launch it in landscape mode it will still launch as portrait . If i want landscape i have to afterwards AGAIN rotate it to landscape .I tried very hard to fix for this but failed . You can download and run the sample code from Apple Developer Site Here . Can anyone fix this code so that if launched in landscape mode it presents the modal view for the landscape view ? Otherwise I'll have to rewrite everything to use a single view controller .
These are the relevant portions of apples code :
- (void)viewDidLoad
{
self.view.backgroundColor = [UIColor colorWithRed:197.0/255.0 green:204.0/255.0 blue:211.0/255.0 alpha:1.0];
LandscapeViewController *viewController = [[LandscapeViewController alloc]
initWithNibName:#"LandscapeView" bundle:nil];
self.landscapeViewController = viewController;
[viewController release];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(orientationChanged:)
name:UIDeviceOrientationDidChangeNotification object:nil];
}
- (void)orientationChanged:(NSNotification *)notification
{
// We must add a delay here, otherwise we'll swap in the new view
// too quickly and we'll get an animation glitch
[self performSelector:#selector(updateLandscapeView) withObject:nil afterDelay:0];
}
- (void)updateLandscapeView
{
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
if (UIDeviceOrientationIsLandscape(deviceOrientation) && !isShowingLandscapeView)
{
[self presentModalViewController:self.landscapeViewController animated:YES];
isShowingLandscapeView = YES;
}
else if (deviceOrientation == UIDeviceOrientationPortrait && isShowingLandscapeView)
{
[self dismissModalViewControllerAnimated:YES];
isShowingLandscapeView = NO;
}
}
// override to allow orientations other than the default portrait orientation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{return (interfaceOrientation == UIInterfaceOrientationPortrait); // support only portrait}
I know this is probably no longer relevant to you, but I just came across the same glitch and here's my solution.
From the way you have your code set out (including how Apple sets it out)
- (void)updateLandscapeView
is only called once a Notification is sent out telling the ViewController of an orientation change: the issue here is, that this is the method responsible for checking the orientation it self. (i.e. Starting the application this method is not called and therefore it doesn't check whether the device is in any other orientation)
The solution is quite simple: Force cal themethod at launch, i.e. in viewDidLoad . . .
[self updateLandscapeView]
This will force call the method and check the interfaces orientation, after the first time, the method will be called again when ever it receives a notification for a changed Orientation
Hope this helps someone Out There
It seems that the device assumes portrait unless you specify landscape only in settings. Your only option would be in your portrait view in the loadview method to detect the orientation and to swap views during launch.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ) {
//Load vertical interface
}
else
{
//load landscape
}
}
I am working on an iPad app (which will not be submitted to the App Store) which supports only landscape mode.
Most of the views in the application are pushed onto a UINavigationController with a hidden navigation bar.
When I add the following code in the top view controller in the aforementioned UINavigationController, the new UINavigationController (navController) is created in portrait mode and appears sideways and off-screen.
MyViewController *myViewController = [[MyViewController alloc] initWithNibName:#"MyView" bundle:nil];
// viewController.view is landscape in MyView.xib
// myViewController is created in landscape mode
NSLog(#"%#", NSStringFromCGRect(myViewController.view.frame)); // {{0, 0}, {1024, 704}}
UINavigationController *navController = [[UINavigationController alloc]
initWithRootViewController:myViewController];
// navController is created in portrait mode (why?)
NSLog(#"%#", NSStringFromCGRect(navController.view.frame)); // {{0, 0}, {768, 1024}}
[self presentModalViewController:navController animated:YES];
// navController is shifted off-screen after it is presented modally (why?)
NSLog(#"%#", NSStringFromCGRect(navController.view.frame)); // {{1024, 0}, {748, 1024}}
I cannot find any possible reason for this to occur, nor can I figure out how to reorient the view to landscape mode; I can change its frame but its content is still sideways.
I tried adding the following to MyViewController.m to no avail:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return !UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
I even tried adding this code to a UINavigationController subclass which did not work either.
I was able to get the view navigation controller to orient itself correctly by adding it as a subview of my application's root view.
MyRootViewController *myRootViewController = [[[UIApplication sharedApplication] delegate] myRootViewController];
[myRootViewController presentModalViewController:navController animated:YES];
This code is in the top view controller of the navigation controller which is a subview of the root view.
Not sure if this will work, but you could add this key to your Info.plist to indicate what orientation your app supports (at least, this will prevent it from starting in portrait):
UISupportedInterfaceOrientations~ipad => (UIInterfaceOrientationLandscapeLeft, UIInterfaceOrientationLandscapeRight)
