Wrote an app with Xcode. Clicked the buttons that restrict orientations to be the two portrait options. Changed the plist file to only allow the two portrait orientations. Put the restriction in programatically.
When I build the app to my phone, it rotates into both landscapes and the upright portrait orientation. What the heck?
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return ((interfaceOrientation == UIInterfaceOrientationPortrait) ||
(interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown));
}
The method you're using is part of the controller class, but that method may never get called if the controller class is either not active or not in control of the view on the screen. So your app might be auto rotating because this message is in fact never actually getting called. The solution is to check the connections or initializations of your view controller class to make sure that they are running as you expect.

I am planning to allow user to rotate the devices however during launch, i want the app start from landscape mode. May i know how can i do that?
Here is my code now for the orientation
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
You need to check the orientation of the status bar.
Please check the following links :-
Force iOS app to launch in landscape mode
Modal View Controller force Landscape orientation in iOS 6
Force Landscape Orientation on iOS 6 in Objective-C
In the Project settings/target settings (the blue icon towards the top of the navigation bar on the left, in xcode), there are settings for specifying the orientation. You'll see 4 images, each of which can be selected or deselected.
Select only the one that you want initially for your app, and then you can use the shouldAutorotate and supportedInterfaceOrientation methods to allow or disallow certain orientations.
Supported interface orientations are also specified in the plist. Makes sure to keep the initial orientation for the app at the top of that supoortedInterfaceOrientations list in the plist file.
I'd like the app to work like it would be as if I locked the orientation manually. I'm trying to find how I can lock the orientation for an app. In the info.plist, I have this setting:
Supported interface orientations (iPad)
Item 0 Landscape (right home button)
Item 1 Landscape (left home button)
I thought that would be enough to keep my viewControllers from staying in landscape mode and not portrait. But it does not. Do I need to do
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
in ALL my viewControllers? Thanks!
All though implementing shouldAutorotateToInterfaceOrientation in all your view controllers will work, it is probably not the fastest or most practical way of doing what you are trying to accomplish.
If any of your view controllers in your hierarchy do not conform to the orientation change, then iOS will stop trying to rotate them. What this means is that only your root view controller needs to have implemented shouldAutorotateToInterfaceOrientation with only landscape orientations. Each view controller pushed or added will conform to that function.
I have had to do this in several of my apps and it was required for several reasons.
In the end and after a lot of testing, we determined that the condition has to be set on the info.plist AND on every viewController.
So make sure it is set on the plist and that every shouldAutorotateToInterfaceOrientationonly returns yes for the allowed orientation.
This is because the plist will help you with allowed LAUNCH orientations, but your app could still rotate afterwards, specially when using modal views.
You can download one of my free apps that does thins on iPad: http://itunes.apple.com/mx/app/hoteles-city/id471505865?mt=8
Yes you do.
I have a different solution however. In every UIViewController, I use:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft){
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
} else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
} else {
return NO;
}
}
I'm using xCode 4 for my project which should work both on iPad and iPhone. So, i have created Universal windows based application. I want my application starts into landscape mode so i added following:
in method:
shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
I set interfaceOrientation == UIInterfaceOrientationLandscapeRight
and added the key into application.plist:
Initial Interface Orientation and set it on Landscape (right home button).
Now, the application did start in landscape mode, however, every component in it (button, label) remains rotated 90 degrees (counterclockwise).
When i load xib, Window orientation is set into Portrait and dropdown is disabled.
anybody has idea what i'm doing wrong?
shouldAutorotateToInterfaceOrientation isn't asking you to set the variable (and will have no way of reading the result even if you do), it's a query as to whether the nominated orientation is acceptable. So you want:
- (BOOL)shouldAutorotateToInterfaceOrientation:
(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation == UIInterfaceOrientationLandscapeRight) return YES;
return NO;
}
/* or: return interfaceOrientation == UIInterfaceOrientationLandscapeRight; */
The XIB is a separate issue; neither Interface Builder nor its replacement parts in Xcode 4 can see what you're doing in your code, so they shouldn't just decline to let you design in landscape mode. However, it's the view that is linked to the view member of the relevant UIViewController that you want to set the orientation on, not the window.
How to change a UIImageView into landscapemode?
I have a UIImageview.whe it rotated its still in potrait mode.
code:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
Depending on the class/controller that is holding the view and it's inherited classes, it is likely that one of these is set to only allow portrait rotations.
Please check this and then provide us with more information so that we may advise you better, if what I have said is not the case.
If you only want your app to run in landscape and NOT allow portrait, update the 'Supported interface orientations' list in your app's info.plist to only include the landscape orientations.
I want my iPad app to stop rotation as you rotate the iPad. I want to stop rotate every view.
Any ideas help?
if you want stop rotation for whole app then simply in app info.plist file changed Supported interface orientations ,Initial interface orientation property to portrait or landscape depends on you
In iOS6 shouldAutorotateToInterfaceOrientation has be deprecated. Override both supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation instead.
Please see
Just check the auto-resizing property of your view controller.
(Fixed syntax error)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation == UIInterfaceOrientationPortrait)
return YES;
return NO;
}
In My Project's info.plist I have deleted some key on the iPad Supported interface orientations like the following image (I have only given support for the portrait orientation)
The main idea of global controllable rotation lock is to write UIViewController category containing lock mechanism for every view controller.
You simply need to modify supportedInterfaceOrientations method globally
- (NSUInteger)supportedInterfaceOrientations
{
return __orientation;
}
Here __orientation is the static variable which can be set via category method.
The full realization of the category is presented here
Please update your projectname.plist like this. Supported interface orientations have only one object "Portrait (bottom home button)"
I strongly advise against stop rotation on iPad because supporting rotation is a must on the iPad. This is because the iPad does not have a normal way in which it will be held unlike the iPhone, which is normally held in portrait view (AKA Vertical). So you have to leave the choice to the user to eventually lock the orientation
The HIG do not actually state this as a requirement, but as a recommendation but there are many app that was rejected by this issue.
By the way if you want to this for a limit number of view controller you should implement:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if(interfaceOrientation == UIInterfaceOrientationPortrait){
return YES;
}
}
