iOS 6에서 UIViewController를 세로 방향으로 강제하는 방법

iOS 6에서 UIViewController를 세로 방향으로 강제하는 방법

는 다음과 같이 ShouldAutorotateToInterfaceOrientation아이폰 OS 6에서 사용되지 않는 내가 그에게 특정 뷰를 강제로 사용되는 세로 만 , 아이폰 OS 6에서이 작업을 수행하는 올바른 방법은 무엇입니까? 이것은 내 앱의 한 영역에만 해당되며 다른 모든보기는 회전 할 수 있습니다.

모든 내비게이션 컨트롤러가 상위 뷰 컨트롤러를 존중하도록하려면 카테고리를 사용하여 여러 클래스 이름을 살펴보고 변경할 필요가 없습니다.

@implementation UINavigationController (Rotation_IOS6)

-(BOOL)shouldAutorotate
{
    return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}

@end

몇 가지 의견이 지적했듯이 이것은 문제에 대한 빠른 수정입니다. 더 나은 솔루션은 UINavigationController 하위 클래스이며 이러한 메서드를 거기에 배치하는 것입니다. 하위 클래스는 6과 7을 지원하는데도 도움이됩니다.

iOS6를위한 가장 좋은 방법은 Ray Wenderlich 팀의 "iOS6 By Tutorials"( http://www.raywenderlich.com/ )에 명시되어 있으며 UINavigationController대부분의 경우 서브 클래 싱보다 낫습니다 .

UINavigationController초기 뷰 컨트롤러로 세트 가 포함 된 스토리 보드와 함께 iOS6를 사용하고 있습니다 .

//AppDelegate.m-불행히도 iOS6 이전에는이 ​​메서드를 사용할 수 없습니다.

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskAllButUpsideDown;

if(self.window.rootViewController){
    UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
    orientations = [presentedViewController supportedInterfaceOrientations];
}

return orientations;
}

//MyViewController.m-각각에 대해 지원하려는 방향을 반환합니다. UIViewController

- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskPortrait;
}

이 답변은 OP 게시물의 의견에서 묻는 질문과 관련이 있습니다.

뷰가 주어진 방향으로 나타나도록 강제하려면 viewWillAppear에 다음을 넣으십시오.

UIApplication* application = [UIApplication sharedApplication];
if (application.statusBarOrientation != UIInterfaceOrientationPortrait)
{
    UIViewController *c = [[UIViewController alloc]init];
    [self presentModalViewController:c animated:NO];
    [self dismissModalViewControllerAnimated:NO];
}

약간의 해킹이지만 UIViewController이전 컨트롤러가 가로 모드 인 경우에도 세로로 표시되도록 강제합니다.

iOS7 업데이트

위의 방법은 이제 더 이상 사용되지 않으므로 iOS 7의 경우 다음을 사용하십시오.

UIApplication* application = [UIApplication sharedApplication];
if (application.statusBarOrientation != UIInterfaceOrientationPortrait)
{
     UIViewController *c = [[UIViewController alloc]init];
     [c.view setBackgroundColor:[UIColor redColor]];
     [self.navigationController presentViewController:c animated:NO completion:^{
            [self.navigationController dismissViewControllerAnimated:YES completion:^{
            }];
     }];
}

흥미롭게도, 기록의 시간에 하나 , 본 해제 또는 애니메이션되어야한다. 둘 다 그렇지 않으면 흰색 화면이 나타납니다. 이것이 왜 작동하는지 모르겠지만 작동합니다! 시각적 효과는 애니메이션에 따라 다릅니다.

그래서 세로 모드 만 표시 할 때 동일한 문제가 발생했습니다. 일반적으로, 나는를 만들 것 UINavigationController, 설정된 viewController는 AS를 rootViewController다음을 표시 UINavigationController모달보기로. 그러나 iOS 6에서는 viewController이제 navigationController에 지원되는 인터페이스 방향 (기본적으로 모두 iPad 용이고 iPhone 용은 거꾸로되어 있음)을 묻습니다.

솔루션 : UINavigationController자동 회전 메서드 를 하위 클래스로 만들고 재정의해야했습니다. 일종의 절름발이.

- (BOOL)shouldAutorotate {
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}
// pre-iOS 6 support 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}

---

IOS 5

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{

    return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

IOS 6

-(BOOL)shouldAutorotate{
    return YES;
}

-(NSInteger)supportedInterfaceOrientations{

    //    UIInterfaceOrientationMaskLandscape;
    //    24
    //
    //    UIInterfaceOrientationMaskLandscapeLeft;
    //    16
    //
    //    UIInterfaceOrientationMaskLandscapeRight;
    //    8
    //
    //    UIInterfaceOrientationMaskPortrait;
    //    2

    //    return UIInterfaceOrientationMaskPortrait; 
    //    or
          return 2;
}

UIViewController 회전 메서드가 범주 자체에 선언되어 있으므로 다른 범주에서 재정의하면 정의되지 않은 동작이 발생하기 때문에 @aprato 대답에 동의하지 않습니다. UINavigationController (또는 UITabBarController) 하위 클래스에서 재정의하는 것이 더 안전합니다.

또한 가로보기에서 세로 전용 VC로 또는 그 반대로 푸시 / 프레젠테이션 / 팝 시나리오는 다루지 않습니다. 이 어려운 문제를 해결하려면 (Apple에서 해결하지 않음) 다음을 수행해야합니다.

iOS <= 4 및 iOS> = 6 :

UIViewController *vc = [[UIViewController alloc]init];
[self presentModalViewController:vc animated:NO];
[self dismissModalViewControllerAnimated:NO];
[vc release];

iOS 5에서 :

UIWindow *window = [[UIApplication sharedApplication] keyWindow];
UIView *view = [window.subviews objectAtIndex:0];
[view removeFromSuperview];
[window addSubview:view];

이것들은 UIKit이 모든 shouldAutorotate, supportedInterfaceOrientations 등을 재평가하도록 강제합니다.

I have a very good approach mixing https://stackoverflow.com/a/13982508/2516436 and https://stackoverflow.com/a/17578272/2516436

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    NSUInteger orientations = UIInterfaceOrientationMaskAllButUpsideDown;


    if(self.window.rootViewController){
        UIViewController *presentedViewController = [self topViewControllerWithRootViewController:self.window.rootViewController];
        orientations = [presentedViewController supportedInterfaceOrientations];
    }

    return orientations;
}

- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)rootViewController {
    if ([rootViewController isKindOfClass:[UITabBarController class]]) {
        UITabBarController* tabBarController = (UITabBarController*)rootViewController;
        return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];
    } else if ([rootViewController isKindOfClass:[UINavigationController class]]) {
        UINavigationController* navigationController = (UINavigationController*)rootViewController;
        return [self topViewControllerWithRootViewController:navigationController.visibleViewController];
    } else if (rootViewController.presentedViewController) {
        UIViewController* presentedViewController = rootViewController.presentedViewController;
        return [self topViewControllerWithRootViewController:presentedViewController];
    } else {
        return rootViewController;
    }
}

and return whatever orientations you want to support for each UIViewController

- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskPortrait;
}

I have a relatively complex universal app using UISplitViewController and UISegmentedController, and have a few views that must be presented in Landscape using presentViewController. Using the methods suggested above, I was able to get iPhone ios 5 & 6 to work acceptably, but for some reason the iPad simply refused to present as Landscape. Finally, I found a simple solution (implemented after hours of reading and trial and error) that works for both devices and ios 5 & 6.

Step 1) On the controller, specify the required orientation (more or less as noted above)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    NSInteger mask = UIInterfaceOrientationMaskLandscape;
    return mask;

}

Step 2) Create a simple UINavigationController subclass and implement the following methods

-(BOOL)shouldAutorotate {
        return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
        return UIInterfaceOrientationMaskLandscape;
}

Step 3) Present your viewController

vc = [[MyViewController alloc]init];
MyLandscapeNavigationController *myNavigationController = [[MyLandscapeNavigationController alloc] initWithRootViewController:vc];
[self myNavigationController animated:YES completion:nil];

Hope this is helpful to someone.

Not to be dull here, but would you be so kind to share your subclass? Thank you.

edit: well, I finally did it, the subclass was dead simple to do. I just had to declare the navigationController in the AppDelegate as UINavigationControllerSubclass instead of the default UINavigationController, then modified your subclass with:

- (BOOL)shouldAutorotate {
    return _shouldRotate;
}

so I can set any view I want to rotate or not by calling at viewDidLoad

_navController = (UINavigationController *)self.navigationController;
[_navController setShouldRotate : YES / NO]

Hope this tweak will help others as well, thanks for your tip!

Tip: Make use of

- (NSUInteger)supportedInterfaceOrientations

in your view controllers, so you don't end up by having a portrait desired view in landscape or vice versa.

---

I did not test it myself, but the documentation states that you can now override those methods: supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation.

You can probably achieve what you want y setting only the orientation that you want in those methods.

---

The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well. Launching a portrait-only modal from a landscape tab bar controller failed. If you need to do this, then use the trick of displaying and hiding a non-animated modal view, but do it in the viewDidAppear method. It didn't work for me in viewDidLoad or viewWillAppear.

Apart from that, the solutions above work fine.

---

For Monotouch you could do it this way:

public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
    {
    return UIInterfaceOrientationMask.LandscapeRight;
}

public override UIInterfaceOrientation PreferredInterfaceOrientationForPresentation()
    {
    return UIInterfaceOrientation.LandscapeRight;
}

---

I see the many answer but not get the particular idea and answer about the orientation but see the link good understand the orientation and remove the forcefully rotation for ios6.

http://www.disalvotech.com/blog/app-development/iphone/ios-6-rotation-solution/

I think it is help full.

Just go to project.plist then add Supported interface orientation and then add only Portrait (bottom home button) and Portrait (top home button).

You can add or remove there orientation as per your project requirement .

Thanks

---

1) Check your project settings and info.plist and make sure that only the orientations you want are selected.

2) add the following methods to your topmost view controller(navigation controller/tabbar controller)

- (NSUInteger) supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;

}

3) add the following methods to your app delegate

- (NSUInteger) supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;

}

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    return UIInterfaceOrientationMaskPortrait;

}

---

Put this in the .m file of each ViewController you don't want to rotate:

- (NSUInteger)supportedInterfaceOrientations
{
    //return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft;
    return UIInterfaceOrientationMaskPortrait;
}
