I'm using Xcode 4.3.2 and an iPad simulator 5.1
I really need some help with this, my app is stuck at portrait mode.
When I rotate the simulator
I've tried looking under the project settings and have these checked:
Portrait, Upside Down, Landscape Left and Landscape Right.
I also these methods in the view controllers:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
can anyone please help?
Check your supporting orientations in the project's settings or on *.plist file. Also, if you are using UITabBarController or smth else, all of your controllers have to support all orientations!
use cmd+shift+f and type - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
make sure all of them return YES if you want all orientations supported and NO For unsupported orientations
Make sure you only have one controller showing. I've seen this problem when I have multiple views with different controllers showing at the same time.
Yeah I had the same problem and the other answers here didn't fix my situation. I found I had to check the "Resize View from NIB" box in all the relevant views.
See screenshot below (although shows a slightly older version of XCode).

I'm new to IOS development, and I'm trying to write an app for deployment on an ipad. Partly to keep things simple, layout-wise, and because I believe that my users will only use the app in landscape mode, I wish to only allow landscape views, and completely disable portrait views.
I've found a good deal of advice looking around the internet for an answer. Unfortunately, none of it has worked for me. The best answer I've found was to simply to go the target in xcode, and under "deployment info" -> Device Orientation, simply uncheck "Portrait" and "Upside Down". This should, theoretically, solve my issue, but unfortunately, it does not. The view rotates just as normal to portrait mode.
Going to the info tab and setting the Initial Interface Orientation to Landscape (Left) does make the app at least start in Landscape mode, but it does not restrict it only to that mode.
Even adding
- (BOOL)shouldAutorotate {
return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
into my main view doesn't seem to help anything. So I'm somewhat stumped. There must be some setting or something somewhere which is still allowing portrait views. What might this problem be?
If you look at your AppName-Info.plist file, there should be a key titled 'Supported interface orientations'.
You should remove any of the Portrait values in that dictionary and make sure you only have the Landscape values included!
Edit:
In the question-asker's case, their issue involved a piece of code in the AppDelegate that changed the app's supported orientations.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
/* They had the following:
* return UIInterfaceOrientationMaskAll;
* Which allowed the orientation to rotate to portrait
*/
// This fixed their issue:
return UIInterfaceOrientationMaskLandscape;
}
Hope this helps!
You can do this in General tab in your project
Seems like a simple thing to do right? Go to the Target's Summary tab and set "Supported Interface Orientations" to Landscape Right only. You would think that would mean the app would be landscape only. But no.
On a device running 5.1 for example, if you open the app and hold the phone in the correct landscape right position you will see the view rotated 90 degrees counterclockwise, as if it think it's supposed to be in portrait mode, unless you add something like this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
But that only works for one view controller, and who knows if it works on all OS versions.
So how do you make an app landscape only? Do I have to add that code to every single view controller in the app? I do not need any rotation. All my views are designed in Landscape. I just want the app to open in Landscape Right mode and stay that way. And I want to support iOS 5 and up.
There are new methods introduced that you have to implement along with the old one they are as below
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
In Xcode you can navigate to your project settings -> summary -> iPhone/iPod deployment info. Here you can select the supported interface orientations. You can also edit the 'Supported interface orientations' array in your application's info.plist by adding the desired interface orientations application wide.
In the info.plist put the orientation to landscape
My app is entirely designed for IOS6. I use an xib for the iPhone and another one for the iPad. My AppDelegate sets up a TabBarController, though there is no class for the TabBarController itself. The TabBarController has two tab items, 1 a NavigationController, and 1 a View Controller, each of which has its own class. I would like the iPad to be able to run in just Portrait mode, upside down, and normal. On the summary tab of Target in Xcode, I have supported interface orientations set to Portrait and Portrait Upside Down.
My understanding with iOS 6 is that you only need to put
- (NSUInteger)supportedInterfaceOrientations
in the highest parent controller of a class, and set which Masks you would like it and all the child containers to work with. So, in the Root View Controller of the Navigation Controller I put:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskPortraitUpsideDown;
}
And in each of the child classes, I put:
- (BOOL)shouldAutorotate{
if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
{
return YES;
}
else
{
return NO;
}
}
I then put the same two methods in the 2nd Tab which was just a View Controller Class.
I installed the app on my iPad, and it worked fine in portrait mode, but did not rotate when I turned it upside down. I exited the app and turned the iPad upside down, but when I started the app again, it still stayed in the same spot. So, I killed the app completely, and started it from the beginning upside down. The splash screen was upside down, but when the screen disappeared, the app was still only showing in portrait mode, making the display upside down.
What am I missing?
click on appName select Target and just select the orientations which you want to support. thanks
The code above is great for pre iOS 6. For iOS 6 you have to use the mask orientation. If you want all of the views in iPad to rotate or just some you have the choice of using the above answer. If you want to hard code it the check my answer in the following link for a detailed code for autorotation of all masks or just rotate one view and let the others don't rotate. Any how here is the link
iOS 6 supportedInterfaceOrientations issue
The above answer is providing you with the right solution as well but if you want to learn how to code it check my answer in the link above. Happy coding.
Is the Rotation Lock enabled or not ? (If you are new to iOS, double tap the home button, and slide to the right: it's the little metal-styled button in shape of an arrow).
If you want to run your application to run on portrait mode only than,
1. Select Your Target.
2. In General -> Development Info -> Device Orientation Uncheck all other orientation.Portrait mode only should be checked.Than run your project.
I have downloaded an example code from here and tested it out. The thing I wasn't able to understand is that when I set the orientation to Landspace only and run it in Portrait mode, nothing changes.. I mean I should still be able to see the menu on left and the Psychologist button shouldn't be there.
PS: With iOS6, it is working well but lower versions giving me the same result.
It looks like in the RoatatableViewController.m file the method
- (BOOL)shouldAutorotateToInterfaceOrientation:
Is telling the app that rotation is okay in all directions.
You should use this to block to landscape mode for iOS 5 and older:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
It just looks like the person who made this project up in Stanford overlooked this.
I searched for other existing posts, but none of them satisfied my requirements.
Here is the problem i face,
My app supports both the Modes , landscape and portrait.
But my first screen only supports Landscape , so the app must start in Landscape.
I have set supported Orientation to all the 4 options
I have set the Initial interface orientation to Landscape (left home button)
In the view controller of the first screen i am defining the below
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortrait);
}
And when i start the app the simulator always opens in Portrait and my view is all messed up in the portrait mode , since it is designed only for the landscape.
After the switch to the Landscape, the device remains in this mode.
can anyone help me with the solution to avoid this ?
Thanks
Naveen
EDITED :
This info may be helpful , The problem is faced only when i hold the device in Portrait and then launch the app.
Its not the duplication of this question, Landscape Mode ONLY for iPhone or iPad
Landscape Mode ONLY for iPhone or iPad
I do not want my app to be only in Landscape , i want only the first screen of my app to be only in Landscape.
I did some experimenting with an app I'm working on that has the same requirements, and came up with the following:
To set the initial orientations that are supported when the app is first launched, use the "Supported Device Orientations" setting for your target.
Also back that up with the appropriate shouldAutorotateToInterfaceOrientation code, as you've already done.
For subsequent screens, simply use the shouldAutorotateToInterfaceOrientation code to determine which orientations you want to support. Even if you've specified only landscape modes for the Supported Device Orientation, shouldAutorotateToInterfaceOrientation wins. :)
I think this approach is a little cleaner than using an extra dummy VC.
I achieved a workaround for the Problem and it solved ,
I created a dummy view controller and added as the root view controller of the Window.
Added the below method in the implementation
-(void)viewDidAppear:(BOOL)animated
{
WelcomeScreen *welcomeScreen = [[[WelcomeScreen alloc] initWithNibName:#"WelcomeScreen" bundle:nil] autorelease];
[self presentModalViewController:welcomeScreen animated:NO];
}
Now it worked as expected.
Here is a SO link that will hopefully answer your question on how to launch your app in landscape mode.
