Try add <code>shouldAutorotate</code> method

blocks|key|260076|text|首先，为了让你的应用程序只在模式下工作，你应该返回UIInterfaceOrientationMaskLandscape。如果你只想保持纵向模式，你的做法是正确的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|260077|只需在Info.plist中添加UISupportedInterfaceOrientations键，并指定您的应用程序想要保留的界面方向值。|260078|此外，你应该从shouldAutoRotate返回false，以防你想要完全避免自动旋转。但我建议你从这里返回true，并在supportedInterfaceOrientations方法中指定正确的方向。|260079|entityMap^0|P|Z|0|G|W|0|7|G|1Q|U|0^^$0|@$1|2|3|4|5|6|7|L|8|@$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|J|3|-4|5|6|7|W|8|@]|D|@]|E|$]]]|K|$]]

Firstly in order to make your app work in only mode you should be returning <code>UIInterfaceOrientationMaskLandscape</code>. In case you want to keep only portrait mode, you are doing things correctly.

Just add the <code>UISupportedInterfaceOrientations</code> key in the Info.plist and assign the interface orientation values your app intends to keep.

Also, you should be returning false from <code>shouldAutoRotate</code> in case you want to avoid auto rotation totally. But I would suggest you to return true from here and specify the correct orientations in <code>supportedInterfaceOrientations</code> method.

So in the UINavigationController subclass I need to check which orientation is supported by the current topViewController.

One thing I've found is if you have an old application that is still doing

<pre><code>[window addSubView:viewcontroller.view]; //This is bad in so may ways but I see it all the time...
</code></pre>

You will need to update that to:

<pre><code>[window setRootViewController:viewcontroller]; //since iOS 4
</code></pre>

Once you do this the orientation should begin to work again.

If you are using <code>UINavigationController</code>, you have to implement <code>shouldAutorotate</code> and <code>supportedInterfaceOrientations</code> in subclass of <code>UINavigationController</code>.

These are able to control by two steps, if <code>shouldAutorotate</code> returns YES then effective <code>supportedInterfaceOrientations</code>. It's a very nice combination.

This example, my mostly views are Portrait except CoverFlowView and PreviewView.
The CoverFlowView transfer to PreviewView, PreviewView wants to follow CoverFlowCView's rotation.

<pre><code>@implementation MyNavigationController

-(BOOL)shouldAutorotate
{

if ([[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"PreviewView")])

return NO;

else

return YES;

}



-(NSUInteger)supportedInterfaceOrientations

{

if ([[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"CoverFlowView")])

return UIInterfaceOrientationMaskAllButUpsideDown;

else

return UIInterfaceOrientationMaskPortrait;

}

The best way I think is to do a Category rather than subclassing <code>UINavigationController</code> or <code>UITabbarController</code>

your UINavigationController+Rotation.h

<pre><code>#import &lt;UIKit/UIKit.h&gt;

@interface UINavigationController (Rotation)

@end
</code></pre>

your UINavigationController+Rotation.m

<pre><code>#import "UINavigationController+Rotation.h"

@implementation UINavigationController (Rotation)

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

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

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


@end
</code></pre>

Try to make all your controller import this category and this work like a charm. 
You can even make a controller not rotating and pushing another controller that will rotate.

The best way for iOS6 specifically is noted in "iOS6 By Tutorials" by the Ray Wenderlich team - <a href="http://www.raywenderlich.com/" rel="nofollow">http://www.raywenderlich.com/</a> and is better than subclassing UINavigationController for most cases.

I'm using iOS6 with a storyboard that includes a UINavigationController set as the initial view controller.

//AppDelegate.m - this method is not available pre-iOS6 unfortunately

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

The answers here pointed me in the correct direction although I couldn't get it to work by just cut and pasting because I am using UINavigationControllers inside of a UITabBarController. So my version in AppDelegate.m looks something like this, which will work for UITabBarControllers, UINavigationControllers or UINavigationControllers within a UITabBarController. If you are using other custom containment controllers, you would need to add them here (which is kind of a bummer).

<pre><code>- (UIViewController*)terminalViewController:(UIViewController*)viewController
{
 if ([viewController isKindOfClass:[UITabBarController class]])
 {
 viewController = [(UITabBarController*)viewController selectedViewController];
 viewController = [self terminalViewController:viewController];
 }
 else if ([viewController isKindOfClass:[UINavigationController class]])
 {
 viewController = [[(UINavigationController*)viewController viewControllers] lastObject];
 }

 return viewController;
}

- (NSUInteger)application:(UIApplication *)application
supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
 NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
 UIViewController* viewController = [self terminalViewController:window.rootViewController];

 if (viewController)
 orientations = [viewController supportedInterfaceOrientations];

 return orientations;
}
</code></pre>

Another key thing to note is that you must override supportedInterfaceOrientations in your UIViewController subclasses or it will default to what you specified in your Info.plist.

blocks|key|260685|text|正如其他人所说的，如果您正在使用UINavigationController，并且您想要定制各种视图，那么您将希望对UINavigationController进行子类化，并确保拥有以下两个组件：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|260686|@implementation+CustomNavigationController

-+(BOOL)shouldAutorotate
{

}|code-block|syntax|javascript|260687|然后，在任何仅为肖像的视图中，您将包括：|260688|-+(NSUInteger)supportedInterfaceOrientations

As stated by others if you're using a UINavigationController and you want to customize various views you'll want to subclass the UINavigationController and make sure you have these two components:

<pre><code>@implementation CustomNavigationController

// -------------------------------------------------------------------------------
// supportedInterfaceOrientations:
// Overridden to return the supportedInterfaceOrientations of the view controller
// at the top of the navigation stack.
// By default, UIViewController (and thus, UINavigationController) always returns
// UIInterfaceOrientationMaskAllButUpsideDown when the app is run on an iPhone.
// -------------------------------------------------------------------------------
- (NSUInteger)supportedInterfaceOrientations
{
 return [self.topViewController supportedInterfaceOrientations]; 
}

// -------------------------------------------------------------------------------
// shouldAutorotate
// Overridden to return the shouldAutorotate value of the view controller
// at the top of the navigation stack.
// By default, UIViewController (and thus, UINavigationController) always returns
// YES when the app is run on an iPhone.
// -------------------------------------------------------------------------------
- (BOOL)shouldAutorotate
{
 return [self.topViewController shouldAutorotate];
}
</code></pre>

Then in any view that is a portrait only you would include:

<pre><code>- (NSUInteger)supportedInterfaceOrientations
{
 return UIInterfaceOrientationMaskPortrait;
}
</code></pre>

And in any view that is everything but upside down:

<pre><code>- (NSUInteger)supportedInterfaceOrientations
{
 return UIInterfaceOrientationMaskAllButUpsideDown;
}
</code></pre>

In my app I have multiple views, some views need to support both portrait and landscape, while other views need to support portrait only. Thus, in the project summary, I have all selected all orientations.

The below code worked to disable landscape mode on a given view controller prior to iOS 6:

<pre><code>- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
 // Return YES for supported orientations
 return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
</code></pre>

Since shouldAutorotateToInterfaceOrientation was deprecated in iOS6 I've replaced the above with:

<pre><code>-(NSUInteger)supportedInterfaceOrientations{
 return UIInterfaceOrientationMask.Portrait;
}
</code></pre>

This method is correctly called when the view appears (I can set a breakpoint to ensure this), but the interface still rotates to landscape mode regardless of the fact that I'm returning the mask for portrait modes only. What am I doing wrong?

It seems that it's currently impossible to build an app that has different orientation requirements per view. It seems to only adhere to the orientations specified in the project summary.

iOS6: supportedInterfaceOrientations not working (is invoked but the interface still rotates)
