iOS6 的方向问题

Question

我在 iOS 6 上的应用方向有问题。 即使它设置为"横向（右主页按钮）"和"横向（左主页按钮）"，它也显示为扭曲应用程序的"纵向"。

我一直在尝试使用RootViewController.m，但没有运气！

这是代码，有人可以帮助我吗？

    @implementation RootViewController
    /*
    // The designated initializer.  Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
// Custom initialization
}
return self;
    }
    */
    /*
    // Implement loadView to create a view hierarchy programmatically, without using a nib.
    - (void)loadView {
    }
    */

    // Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
    - (void)viewDidLoad {
[super viewDidLoad];
    }

    // Override to allow orientations other than the default portrait orientation.
    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
//
// There are 2 ways to support auto-rotation:
//  - The OpenGL / cocos2d way
//     - Faster, but doesn't rotate the UIKit objects
//  - The ViewController way
//    - A bit slower, but the UiKit objects are placed in the right place
//
    #if GAME_AUTOROTATION==kGameAutorotationNone
//
// EAGLView won't be autorotated.
// Since this method should return YES in at least 1 orientation, 
// we return YES only in the Portrait orientation
//
return ( interfaceOrientation == UIInterfaceOrientationPortrait );
    #elif GAME_AUTOROTATION==kGameAutorotationCCDirector
//
// EAGLView will be rotated by cocos2d
//
// Sample: Autorotate only in landscape mode
//
if( interfaceOrientation == UIInterfaceOrientationLandscapeLeft ) {
    [[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeRight];
} else if( interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
    [[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeLeft];
}
// Since this method should return YES in at least 1 orientation, 
// we return YES only in the Portrait orientation
return ( interfaceOrientation == UIInterfaceOrientationPortrait );
    #elif GAME_AUTOROTATION == kGameAutorotationUIViewController
//
// EAGLView will be rotated by the UIViewController
//
// Sample: Autorotate only in landscpe mode
//
// return YES for the supported orientations
return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) );
    #else
    #error Unknown value in GAME_AUTOROTATION
    #endif // GAME_AUTOROTATION

// Shold not happen
return NO;
    }
    //
    // This callback only will be called when GAME_AUTOROTATION == kGameAutorotationUIViewController
    //
    #if GAME_AUTOROTATION == kGameAutorotationUIViewController
    -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
    {
//
// Assuming that the main window has the size of the screen
// BUG: This won't work if the EAGLView is not fullscreen
///
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGRect rect = CGRectZero;

if(toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)      
    rect = screenRect;
else if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
    rect.size = CGSizeMake( screenRect.size.height, screenRect.size.width );
CCDirector *director = [CCDirector sharedDirector];
EAGLView *glView = [director openGLView];
float contentScaleFactor = [director contentScaleFactor];
if( contentScaleFactor != 1 ) {
    rect.size.width *= contentScaleFactor;
    rect.size.height *= contentScaleFactor;
}
glView.frame = rect;
    }
    #endif // GAME_AUTOROTATION == kGameAutorotationUIViewController

    - (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
   // Release any cached data, images, etc that aren't in use.
   }
   - (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
   }

 - (void)dealloc {
[super dealloc];
 }

 @end

请帮帮我！谢谢！

Answer 1

iOS 6 中未使用shouldAutorotateToInterfaceOrientation;请参阅UIViewController文档顶部的"处理视图旋转"。无需进一步的工作，您将只能获得您在项目设置中指定的任何内容。

在 iOS 5 及更早版本下，您已经获得了：

return ( interfaceOrientation == UIInterfaceOrientationPortrait );

因此，在这些系统上，您明确地将此视图控制器限制为纵向。

Answer 2

您需要

在 AppDelegate.mm 文件中检查这一点。检查以下代码行是否存在

// Supported orientations: Landscape. Customize it for your own needs
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
