Is there a possibility that I can programatically say that only 1 UIView can be in landscape mode?
My Whole app has to be in portrait mode (not moving at all) but 1 UIView should be able to go in Landscape mode (To show pictures even better);
You rotate VC like this:
- (BOOL)shouldAutorotate {
return self.topViewController.shouldAutorotate;
}
- (NSUInteger)supportedInterfaceOrientations {
return self.topViewController.supportedInterfaceOrientations;
}
Restrict VC so it won't rotate:
- (BOOL)shouldAutorotate { return NO; }
- (NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait);
}
You could change condition as per your need and this answer is referred from this link so you could go there for more understanding.
Also do keep that iOS 6/7 have different method for checking.If anything else then let me know.
UPDATED:- iOS 7 callBack method for checking mode
– willRotateToInterfaceOrientation:duration:
– willAnimateRotationToInterfaceOrientation:duration:
– didRotateFromInterfaceOrientation:

I am facing problem in view orientation in my app.
Like
I have two view controller, VC1 and VC2
VC1 have fix landscape orientation.
VC2 have both
VC1 -> VC2 is fine. means when I go from VC1 to VC2, VC2 change its orientation in both landscape and portrait.
But when I comeback to VC1 from VC2(where VC2 in portrait mode), VC1 also is in portrait mode but I want VC1 is in landscape only irrespective of VC2 mode.
Please guys help me. Seeking solution from last 2 days.
Thanks in advance.
Refer below link for solution
http://swiftiostutorials.com/ios-orientations-landscape-orientation-one-view-controller/
In your VC1..
-(BOOL)shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeLeft;
}
Hope it helps you...
First of all, write this in AppDelegate.m
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return (UIInterfaceOrientationMaskAll);
}
Then, For VC1, in which landscape orientation, write this:
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait);
}
For VC2, which have both, change masking to All.
- (NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskAllButUpsideDown);
//OR return (UIInterfaceOrientationMaskAll);
}
1. Enable all orientation support for project.
For VC1 Add this line VC1Controller Class
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
For VC2 Add this in VC2Controller Class
- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
basically the view-controller-based orientation support in an iOS app is a piece of cake – I did the code in Swift, but ObjC concept would be totally identical to this.
I have created a quick tutorial with UINavigationController but you can convert that to UITabBarController by keeping the concept but updating the environment slightly.
step-1
initially set the orientation support for your app like this:
step-2
create a simple UINavigationController-based storyboard like this:
NOTE: don't worry if it does not say initially OrientaionSupporterController (bonus point if you'd spot the consistent typo here!), I will cover that just in the very next step.
step-3
create a subset of the navigation-controller, like this:
import UIKit
// MARK: - Implementation
class OrientaionSupporterController: UINavigationController {
// MARK: - Active View Controller
private var activeViewController: UIViewController? {
get {
return self.presentedViewController ?? self.topViewController // for possible modal support
}
}
// MARK: - Orientations
override var shouldAutorotate: Bool {
get {
return self.activeViewController?.shouldAutorotate ?? true // yes, rotate it, please
}
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return self.activeViewController?.supportedInterfaceOrientations ?? .all // default is all possible orientations
}
}
then make sure the that becomes the base class in IB as well:
step-3
create the individual view-controllers with custom orientation support, like e.g. with only portrait and landscape-left support:
import UIKit
// MARK: - Implementation
class ViewController: UIViewController {
// MARK: - Orientation
override var shouldAutorotate: Bool {
get {
return true
}
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return [.portrait, .landscapeLeft] // no one find that preactical but works flawlessly
}
}
NOTE: you can convert this tutorial anytime with UITabBarController, you just need to (obviously) create a subset of the tab-bar-controller and use the selectedViewController to get the currently visible one.
NOTE#2: obviously you can go much further on this way and you can nest the customised navigation-controllers in the view hierarchy, or if you have multiple UIWindow instances in the queue and override the supported orientations there as well for each individual windows (e.g. some support all four orientations, while some other windows does only landscape for e.g. video playback, etc...)
I have a photo app that overlays custom button on camera image picker (for taking picture, turning on/off the flash, other usual stuff etc.)
I want the control interface to support portrait orientation only (I am talking about the control button/interface only, and not the actual captured image), which was working fine till iOS 6.
However, having upgraded to xCode version 5.0 and having upgraded my iPad 3 to iOS 7 (GM Seed, for iPad WiFi 3rd Generation), I find that the camera picker interface auto-rotates when orientation is changed. Surprisingly, I tested the same build on an iPhone 5 (upgraded to iOS 7), but the auto-rotation problem did not manifest itself.
[To be double sure, I tested the same piece of code in iOS 6 again, and the auto-rotation did not happen, neither in iPhone or iPad].
Just to demonstrate how I handle my image picker, here's a bit of code snippet:
UIImagePickerController *pickercustom = [[UIImagePickerController alloc] init];
pickercustom.sourceType = UIImagePickerControllerSourceTypeCamera;
pickercustom.showsCameraControls = NO;
pickercustom.wantsFullScreenLayout = YES;
pickercustom.navigationBarHidden=YES;
pickercustom.view.userInteractionEnabled=YES;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])
{
if (IPAD.userInterfaceIdiom == UIUserInterfaceIdiomPad)
{
pickercustom.delegate = self;
UIDevice *currentDevice = [UIDevice currentDevice];
while ([currentDevice isGeneratingDeviceOrientationNotifications])
[currentDevice endGeneratingDeviceOrientationNotifications];
[self presentViewController:pickercustom animated:YES completion:nil];
while ([currentDevice isGeneratingDeviceOrientationNotifications])
[currentDevice endGeneratingDeviceOrientationNotifications];
}
else
{
pickercustom.delegate = self;
[self presentViewController:pickercustom animated:YES completion:nil];
}
}
The 'endGeneratingDeviceOrientationNotifications' was added to stop the interface from rotating (which hitherto worked fine).
I also tried adding these three methods after reading this: UIImagePickerController in iOS 6 doesn't work properly
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
...but this was, perhaps, an iOS 6 specific solution. It didn't work in my case.
Please let me know if you could figure out the root cause. It would be great help.
You are close. When you want to support rotation but want that one viewController to not rotate, things get tricky:
The UIResponder chain REALLY wants the whole app to have the same rotation. Just simply overriding the rotation delegate methods in your single class will not work. (FYI, in your case, you will need to subclass UIImagePickerController in order to add those methods.) You need to implement these delegate methods in your root navigation controller (You'll need to have your own sub-class, again), and override them to query the top-most viewController for its desired rotation. Something like:
// Handles the should Auto Rotation for all view controllers
- (BOOL)shouldAutorotate {
if ([self.topViewController conformsToProtocol:#protocol(CustomRotation)]) {
return [self.topViewController shouldAutorotate];
}
// Auto rotate the screen by default.
return YES;
}
// Handles the supported Interface Orientations for all View Controllers by seeing if
// the top level viewController responds to Custom Rotation callbacks.
- (NSUInteger)supportedInterfaceOrientations {
if ([self.topViewController conformsToProtocol:#protocol(CustomRotation)]) {
return [self.topViewController supportedInterfaceOrientations];
}
// The default rotation for the application.
return UIInterfaceOrientationMaskAll;
}
You can't use respondsToSelector: in place of conformsToProtocol: because the selector method will always return YES for any class that derives from UIResponder (so like, everything), and you'll have to override the rotation delegates on each and every UIViewController in your project to make this work. Instead, you can create a blank protocol (CustomRotation). In your custom rotation class require that protocol and include the overridden rotation delegate methods like you have above, with the your desired restrictions.
Lastly make sure your supported interface orientations are set properly in xcode and/or in your Application: didFinishLaunchingWithOptions method.
As far as R&D done by me for the same topic,Imagepicker Camera in IOS7 iPad have default interface to change orientation to landscape .They have designed interface in such a way.We cannot forcefully lock the orientation of it.
If still willing to do you have to use custom ImagePicker use AVCam https://developer.apple.com/library/ios/samplecode/avcam/Introduction/Intro.html
and Custom image picker...
http://www.codza.com/custom-uiimagepickercontroller-camera-view
and forcefully lock there orientation...
I've read almost every post around here regarding my problem but none of the solutions seems to work on my app.
So, I use a custom camera view (with buttons on toolbar and an overlay) that is being presented modally from a view controller. My app only supports landscape left and right for the orientation. And i want to stop the camera view from autorotating when it's being presented. I've put all the methods needed for autorotation on my view controller and my app delegate. I've checked on my plist file too and the supported rotations are correct. But my camera view keeps on rotating to any rotation (portrait and landscape) when I rotate the device, resulting on the overlay and the toolbar being incorrectly positioned. I also can't check on the camera view's orientation because i tried putting NSLog on shouldAutoRotate method, but it doesn't get called at all.
So how can I check the rotation on my custom camera view? And how can I force it to not rotate and stay still?
If my code is needed, I'll post it here. If anyone can help me on it I'll greatly appreciate it because it frustrates me so much right now.
Thank you. Cheers.
Create a new class of "UIImagePickerController" and implement the rotation delegates in the .m file as given,
// For lower iOS versions
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return ((toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) || ((toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)));
}
// For iOS version 6.0 and above
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskLandscape);
}
And make an instance of lets say MyImagePickerController instead of UIImagePickerController, and present it. This will work :)
Create a category for UINavigationController
#interface UINavigationController(autoRotation)
-(BOOL)shouldAutoRotate;
#end
#implementation UINavigationController
-(BOOL)shouldAutoRotate{
return [[self.viewControllers lastobject] shouldAutoRoatate];
}
-(NSUInteger)supportedInterfaceOrientations {
return [[self.viewControllers lastobject] supportedInterfaceOrientations];
}
#end
Implement these two methods in your corresponding view controllers
and return the orientation what u exactly want....
xcode -> file -> new file select cocotouch in the leftpane select objective-c category ->next
select give name Picker category on UIImageImagePickerController from dropdown
import
#interface UIImagePickerController (picker)
-(BOOL)shouldAutoRotate;
-(NSUInteger)supportedInterfaceOrientations;
#end
import "UIImagePickerController+picker.h"
#implementation UIImagePickerController (picker)
-(BOOL)shouldAutoRotate{
return yourOrientation;
}
-(NSUInteger)supportedInterfaceOrientations {
return yourInteger;
}
#end
After this when your device's orientation changed then the method shouldAutoRotate get called from your UINavigationController category at this time you have to find out if cameraview is presented if yes then you have to call shouldAutoRotate of Picker
See the following code
in your view controller's shouldAutoRotate
-(BOOL)shouldAutoRotate{
if([self presentingViewController])// Camera is present
return [instanceOfUIImagePickerController shouldAutoRotate];
return yourOrientaionNeededForThisVC;
}
I seem to be having the opposite problem from this post:
Autorotate in iOS 6 has strange behaviour
When I submitted my paid app to Apple, XCode made me update to iOS 6 on my test devices. I used the GUI in XCode to set my app to display only in portrait mode on the iPhone and only in landscape mode on the iPad. This works great on my iOS 6 iPhone and iPad. In iOS 5, however, the iPad is allowing the app to rotate to portrait, displaying my buttons in a letterbox-like black area that shouldn't be there, and crashing repeatedly.
I am using a Navigation Controller and storyboards.
I know shouldAutorotateToInterfaceOrientation is deprecated in iOS 6, but figuring it should still be called in iOS 5, I tried this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
if ((UIDeviceOrientationIsLandscape(UIDeviceOrientationLandscapeLeft))||(UIDeviceOrientationIsLandscape(UIDeviceOrientationLandscapeRight))) {
return YES;
}
else return NO;
}
else
{
if ((UIDeviceOrientationIsLandscape(UIDeviceOrientationPortrait))||(UIDeviceOrientationIsLandscape(UIDeviceOrientationPortraitUpsideDown))) {
return YES;
}
else return NO; }
// Return YES for supported orientations
}
The above code seems to have done nothing. I am putting it in each of my view controllers; it seems I should really be putting it in my navigation controller, but because I set that up graphically, I'm not sure how to do that. Do I have to subclass my navigation controller and do everything in code? There must be a way to use the storyboard settings for this!
(Note: I am not using AutoLayout and apparently can't because of some older components I am including my software that just plain don't like it.)
What might be causing this? I'd like to fix it before too many people buy the app and complain! Thanks in advance...
I think the code should be like this, where you use "interfaceOrientation", parameter passed into the method for your comparison:
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
if ((UIDeviceOrientationIsLandscape(interfaceOrientation))||(UIDeviceOrientationIsLandscape(interfaceOrientation))) {
return YES;
}
else return NO;
}
else
{
if ((UIDeviceOrientationIsLandscape(interfaceOrientation))||(UIDeviceOrientationIsLandscape(interfaceOrientation))) {
return YES;
}
else return NO; }
So I have incorporated Mr. Grant Davis' FGallery into my app for a photo gallery. It works great other than it is overriding all my rotation methods in my other views and I cannot for the life of me figure out how to stop it. Here's a snippet from FGallery's FGalleryViewController that handles the gallery:
#implementation UINavigationController (FGallery)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if([self.visibleViewController isKindOfClass:[FGalleryViewController class]]) {
return YES;
}
// we need to support at least one type of auto-rotation we'll get warnings.
// so, we'll just support the basic portrait.
return ( interfaceOrientation == UIInterfaceOrientationPortrait ) ? YES : NO;
}
I have tried changing the line:
return ( interfaceOrientation == UIInterfaceOrientationPortrait ) ? YES : NO;
but that forces all views to that specific orientation. Some of my views allow for rotation and some do not. So I guess my question is, how can I alter this line to allow rotation in some views and not in others? I'm drawing a blank this morning!!
Any help or ideas here would be appreciated!!
So I'm gonna go ahead and answer my own question.
The answer is to remove the code that overrides the rotation:
#implementation UINavigationController (FGallery)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if([self.visibleViewController isKindOfClass:[FGalleryViewController class]])
{
return YES;
}
// we need to support at least one type of auto-rotation we'll get warnings.
// so, we'll just support the basic portrait.
return ( interfaceOrientation == UIInterfaceOrientationPortrait ) ? YES : NO;
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
// see if the current controller in the stack is a gallery
if([self.visibleViewController isKindOfClass:[FGalleryViewController class]])
{
FGalleryViewController *galleryController = (FGalleryViewController*)self.visibleViewController;
[galleryController resetImageViewZoomLevels];
}
}
#end
And call:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
within #implementation FGalleryViewController
Hopefully this helps someone else out that needs it.
