请不要建议我在 1 个版本中轮换 ios 4.3-6.0 是一个坏主意，因为我告诉过很多次但没有听我的。

在项目设置中，我已将所有界面方向设置为受支持，以确保。

现在我正在用 iphone4 在 ios6 上进行测试。从 app delegate 开始，它是一个代码，如下所示：

mainController = [[MainViewController alloc] initWithNibName:nil bundle:nil];

navigationController=[[RotatingNavigationController alloc] initWithRootViewController:mainController];          
navigationController.navigationBar.hidden =true;

// ios: 4 and 5
//[window addSubview:navigationController.view];

//ios6:
window.rootViewController = navigationController;

[window makeKeyAndVisible];

所以我做了2个自定义类，在可能的情况下推荐用于自动旋转，并且为他们解决了问题。

RotatingNavigationController 是一个自定义UINavigationController的，代码有点难看，但是我从这个论坛收集了这些部分，所以应该允许发布它：

@implementation RotatingNavigationController

- (id)init {
    self = [super init];
    if (self) {        
        self.view.autoresizesSubviews = YES;
        [self.view setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
    }
    return self;
}

// ios6 require this method for rotation detection, available from ios5, ios4.3 not available: sux
//- (void)viewWillLayoutSubviews
//{
    //UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;

    //[[NSNotificationCenter defaultCenter]     postNotificationName:UIDeviceOrientationDidChangeNotification     object:nil];

//    [[NSNotificationCenter defaultCenter] addObserver:self                                              selector:@selector(orientationChanged:)                                                  name:UIDeviceOrientationDidChangeNotification                                                object:nil];

    /*
    if(UIInterfaceOrientationIsLandscape(statusBarOrientation)){
        [self willRotateToInterfaceOrientation: statusBarOrientation duration: 0.3 ];
    }
    else{
        [self willRotateToInterfaceOrientation: statusBarOrientation duration: 0.3 ];
    }
    */
//}

//ios 4.3 and ios 5.0, at ios6 it isn't called by iOS...sux
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
    [self.visibleViewController willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
}

// //ios 4.3 and ios 5.0, at ios6 need different methods, which sux
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
} 

//Autorotation is changing in iOS 6. In iOS 6, the shouldAutorotateToInterfaceOrientation: method of UIViewController is deprecated. In its place, you should use the supportedInterfaceOrientationsForWindow: and shouldAutorotate methods.


// ios6
- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    return UIInterfaceOrientationMaskAll;
}

// ios6
- (BOOL)shouldAutorotate
{
    return YES;
}
// ios6
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationMaskPortrait;
}
@end
  • 这应该会正确生成自动旋转通知，我认为他完成了他的工作。

这MainViewController是一种习惯UIViewController。

只是为了确保我已经复制粘贴了代码：

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    //    return (interfaceOrientation == UIInterfaceOrientationPortrait);
    return YES;
}

// ios6:
- (NSUInteger)supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    return UIInterfaceOrientationMaskAll;
}

// ios6
- (BOOL)shouldAutorotate
{
    return YES;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationMaskPortrait;
}

他的工作是根据设备状态（旋转）更改不同的 UIViewController

我在某个地方有一个菜单屏幕，它有不同的 xib，但也有 h 和 m 文件（因为有不同的元素，不会出现在 Portait 或 Landscape 中。（我没有能力改变整个架构）

代码的一部分 - 这里应该有一些问题，我认为在这个主控制器下面：

#pragma mark
#pragma mark Rotation
- (void)orientationChanged:(NSNotification *)notification
{
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
    UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation; 

    if(deviceOrientation == UIDeviceOrientationFaceUp || deviceOrientation == UIDeviceOrientationFaceDown){
        if(debug){
            NSLog(@"Nothing to change because it is gone to Flat");
        }
        return;
    }
NSArray *viewControllers = [self.navigationController viewControllers];

if (UIDeviceOrientationIsLandscape(deviceOrientation)){

        //if(debug)
        //    NSLog(@"Portait -> Landscape size : %3.0fw, %3.0fh", self.view.bounds.size.width, self.view.bounds.size.height);
        id lastviewController = viewControllers.lastObject;
        // check what is there:
        if([lastviewController isKindOfClass:[MenuController class]]){                 
            [self.navigationController popViewControllerAnimated:NO];
            [self.navigationController pushViewController:menuLandscape animated:NO];
            NSLog(@"poped Menu Portrait, pushed Menu Landscape");
        }
...
else if(UIDeviceOrientationIsPortrait(deviceOrientation)){
    //else if(UIInterfaceOrientationIsLandscape(statusBarOrientation)){

        //if(debug)
        //    NSLog(@"Landscape -> Portait , size : %3.0fw, %3.0fh", self.view.bounds.size.width, self.view.bounds.size.height);
        id lastviewController = viewControllers.lastObject;
        // check what is there:
        if([lastviewController isKindOfClass:[MenuLandscapeController class]]){
            [self.navigationController popViewControllerAnimated:NO];            
            [self.navigationController pushViewController:menuPortait animated:NO];
        } 
...

问题是：景观被取出并被​​推到肖像上，当它倒置时，但那个肖像没有旋转并且它显示出一个破碎的布局。

我怎样才能唤醒那个控制器并告诉他该旋转了，因为它不是纵向模式？

感谢与我关于架构更改之外的任何改进的问题相关的任何建议。

更新：

在 app delgate 没有帮助添加：

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

其他答案的代码：在此处介绍

更新2：

UIInterfaceOrientation statusBarOrientation = [UIApplication sharedApplication].statusBarOrientation;

由于某种原因不想UIInterfaceOrientationPortraitUpsideDown = UIDeviceOrientationPortraitUpsideDown取值，我认为需要解决。

Update3：非常仔细地阅读了两次和第三次ios6 发行说明

系统通过将应用程序的supportedInterfaceOrientationsForWindow: 方法返回的值与最顶部全屏控制器的supportedInterfaceOrientations 方法返回的值相交来确定是否支持方向。

将此类别添加到不旋转的视图控制器

@implementation UINavigationController(Rotation)

-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

@end
