objective-c - ios 6 App 正在旋转，即使使用 shouldAutorotate:NO

Question

从 iOS6 开始，我在旋转方面遇到了很大的问题。我实现了所有新的旋转方法（shouldAutorotate、preferredInterfaceOrientationForPresentation、supportedInterfaceOrientation），但所有视图仍在旋转。有趣的是，视图保持它们的大小，而窗口的其余部分（在景观中）是黑色的。

这就是我实现它的方式，有什么问题吗？

#pragma mark -
#pragma mark - InterfaceOrientation iOS 5 
//Deprecated in iOS 6
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

#pragma mark -
#pragma mark - InterfaceOrientation iOS 6

- (BOOL)shouldAutorotate{
    return NO;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationPortrait;
}

- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskPortraitUpsideDown;
}

谢谢你们的帮助。

我通过为导航控制器创建一个类别解决了这个问题：

@implementation UINavigationController (iOS6fix)

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

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

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

@end

感谢大家的回答！

我也有，即使我把它调成NO，它也会旋转。

两种选择：

1. 转到您的项目设置并更改可能的方向

2. 删除 AUTOROTATE 的所有方法。即使它们设置为 NO，它们也会为我旋转。

Answer 3

我在 UIViewController 上使用了以下类别，仅在 iOS5 和 6 上具有横向。也许它可以帮助某人。

#import <UIKit/UIKit.h>

@implementation UIViewController (iOS6fix)

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeLeft;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

@end

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{
    //Make sure your window to assgin the view controller object to rootViewController, Please don't add controller view as a sub view on window.
    self.window.rootViewController = viewController;
}
