For a couple of different reasons, I'd like to ensure that my app only runs in landscape left orientation. I've unselected all of the other orientations under "Supported Device Orientations" in the target summary, set all of my storyboards to landscape, and added this to all of my classes:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
but I'm still having some problems. It launches into landscape left and that view remains in landscape left no matter what, but when I press a button that pushes a new view, it pushes the view but that one rotates if the device is turned. It also defaults back into portrait if I push another view and then press back in the navigation controller bar. Is there something more aggressive I need to do to ensure that all view controllers remain in landscape left at all times?

I need to know if there is a way to tell a iOS7 device to set a views orientation without the device being rotated. Some way in code to trigger the device to calling the code that tells it which way to display the view.
If the device is in landscape and remains held in landscape orientation while a certain change happens I want to force a change to show the view in portrait orientation, at which point the user would need to turn the device to look at it properly. I'll explain why below
Looking at my app might make my description clearer - it is free to download
I have a number of view controllers (embedded in navigationControllers) and only one of them needs to be rotated into landscape and then only under certain conditions.
Solutions here on StackOverflow seem to be to make a category on UINavigationController giving it shouldAutorotate and supportedInterfaceOrientations methods and then use those methods in the individual viewControllers to block or allow rotations.
This has worked for me .... however
On the one view controller I wish to rotate , I don't want it to rotate all the time.
This view controller is the diveSiteDetailsController, (if you have downloaded the app you need to select dive sites on the first page then click the '+' to see it). It has a UISegmentedController and 4 subviews (3 tableviews and 1 other UIView). The current version on the App Store works fine now i've solved this - but looking at it may help you understand my issue better).
On diveSiteDetailViewController the UISegmentedController is used to switch between the 4 subviews.
All the subviews are used to enter data about the same dive site but as there is a lot of potential data, I have broken it into logical chucks each of which is a subview - location, data (depths,currents, visibility), type of environment and notes.
The .hidden property of each subview is used to make them appear and disappear.
I only want the second subview to rotate (the data view - it has some sliders on it that are easier to work with if in landscape).
restricting this rotation is easy - iI achieved it like this
- (NSUInteger)supportedInterfaceOrientations{
if (self.dsDataRangeSlidingTV.hidden) {
return UIInterfaceOrientationMaskPortrait;
}
return UIInterfaceOrientationMaskAllButUpsideDown;
}
Now the view will only rotate to landscape when the data table view is displayed.
However, once in landscape, if I chose a different subview with the UISegmentedController then they are, obviously, shown in landscape also as the iOS device hasn't done a rotation. This is the situation I am trying to avoid.
Rotating the iOS device will return those views to portrait as expected but i need to trigger the device to to reevaluate its display when I use the UISegmentedController to switch from the data subview to another subview and its that triggering that I don't know how to do.
any suggestions greatly received.
Heres a workaround that is working for me
I've added the following few lines to the end of my method that responds to the UISegmentedControl being tapped.
UIViewController *aDummyController = [[UIViewController alloc]init];
[self presentViewController:aDummyController animated:NO completion:nil];
[self dismissViewControllerAnimated:NO completion:nil];
adding a new viewController and popping it off triggers the rotation . This is a kludgey way of achieving what I wanted.
I found the solution in this post
Is there a documented way to set the iPhone orientation?
all credit to Josh who although not the accepted answer is the one that 99 people currently have up voted.
I still have a bug in that, if I were holding the device in landscape (although the display is portrait view) whilst on the screen that segues into the diveSiteDetailsController then the initial view the diveSiteDetailsController display will be in landscape.
To get around this I created a Bool property called notThisTime on the diveSiteDetailsController and set it to true in the prepareFor Segue on the viewController that called it.
i then did changed supportedInterfaceOrientation to
- (NSUInteger)supportedInterfaceOrientations
{// DLog(#"Running %# '%#'", self.class, NSStringFromSelector(_cmd));
if (self.notThisTime){
return UIInterfaceOrientationMaskPortrait;
}
if (!self.dsDataRangeSlidingTV.hidden) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
then at the end of the ViewDidLoad method I added
self.notThisTime = NO;
I would still love to hear from anyone with a suggestion how better to handle this. pushing and popping a dummy view to get the iPhone to do an orientation check seems like a work around for something that should just be available as a standard method call.
One final Note - the iOS simulator does not like this - you need to check on the device - it sometimes tries to draw the iPhone container in landscape while the screen is drawn vertically - however it does work fine on the iPhone
My Project have 2 views 1. Mainview controller 2. Settingview Controller .
I want my main view controller to support all orientations but the setting view controller should be in landscape mode irrespective of the device orientation. Right now I am facing issues like
1. Even if the scene is in landscape mode the view appears as portrait
2. (BOOL)shouldAutorotate , (NSUInteger)supportedInterfaceOrientations not getting fired.
Any help is appreciated.
I have two "pages" in my app. one which should rotate between the 2 landscape modes but not allow portrait mode and the other which should rotate between the 2 portrait modes but not allow landscape mode.
How can one set this up so that the orientations are limited correctly when segueing between the two views?
I will write my own segue if I were you and set the orientation of the destination view in the perform method of your custom UIStoryboardSegue and will also set the orientation i want to allow in the shouldAutorotateToInterfaceOrientationof the destination view controller. You can have a look to this question related to custom segue I asked some time ago to get an idea of how to implement custom segue.
I've trying to implement autorotate but my app is not listening to me!
The app has a tab bar controller which supervises 3 view controllers. The tab bar is created programatically in the app delegate. Each of the view controllers has this standard simple method:
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
The app delegate looks like this:
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:gameVC, settingsVC, helpVC, nil];
self.window.rootViewController = self.tabBarController;
In addition, in the target summary area I have all 4 orientations for both the iPad and iPhone activated.
In the simulator, no rotation occurs with either device. I seem to be missing something. Perhaps one more setting is needed? Something out of order? There is nothing else in the project related to rotating views.
The only thing that you seemed to not have said in your response that I can think of is changing the device orientations under your info.plist. I know from personal experience that if you click on the supported device orientations in the target summary area, it might not actually change it in the Info property list. Check and make sure that all four are selected in the property list by doing the following:
Go to your Info.plist
Look under Supported interface orientations and Supported interface orientations (iPad)
Make sure that it has 4 strings under both: Portrait (bottom home button), Portrait (top home button), Landscape (left home button), Landscape (right home button)
User a ViewController for super purpose, and then inheritance it in the each of view controllers. In the super ViewController add this
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return YES;
}
So, you just need to do once to make them autorotate

Tab bar controllers support a portrait orientation by default and do
not rotate to a landscape orientation unless all of the contained view
controllers support such an orientation. When a device orientation
change occurs, the tab bar controller queries its array of view
controllers. If any one of them does not support the orientation, the
tab bar controller does not change its orientation.
#Zack #AlexanderZats This was subtle. I was reading this SO answer which brought me here This 2nd link is a great discussion of different possible reasons an app may not rotate. The last point caught my attention. Sure enough, I was overriding initWithNibName and not calling super on it. I think this ultimately meant that the the VCs were not in the responder chain. A huge thanks to all who gave me ideas and suggestions!
I have some 10 view controllers contained in a TabBarController. We have a requirement wherein one view controller out of these 10 view controllers should always be displayed in landscape mode.
Now, when we override:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
and return YES only for Landscape mode in such view controllers, it has not effect. The view controller appears in Portrait mode only.
Probably this is done for a good reason, since when the user switches to a tab whose view controller should support only landscape mode, the whole screen components (including the tabbar) should be rotated to landscape mode, which looks awkward.
Am I right in assuming the cause?
Also, what would be the best way to tackle this? Provide an intermediate view controller in portrait mode and then push the landscape view controllers through it?
Thanks,
Raj
