Question

我目前正在构建一个iOS应用程序，唯一支持的方向是左右横向。我已经用几种方式指定了这个：

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
    return UIInterfaceOrientationIsLandscape(toInterfaceOrientation); //iOS 5 compatibility.
}
-(NSInteger)supportedInterfaceOrientations:(UIWindow *)window{
    return UIInterfaceOrientationMaskLandscape; //iOS 6
}
-(BOOL)shouldAutorotate{
    return YES;
}

我已经将支持的方向指定为应用的Info.plist中的横向方向。当我在我的设备上运行应用程序（甚至在模拟器中）时，我知道根视图是横向的（切换器位于屏幕的长边，通知中心也是如此），但是内容仍然来自于屏幕的左上角，好像处于纵向模式，而不是左下角或右上角，就像我想要的那样。我不知道是什么原因导致内容不能与父视图一起旋转，因为此代码适用于iOS 5，但不适用于iOS 6。

编辑：Here's a screenshot.

编辑：这是我的main.m：

#import <UIKit/UIKit.h>
int main(int argc, char **argv) {
    NSAutoreleasePool *p = [[NSAutoreleasePool alloc] init];
    int ret = UIApplicationMain(argc, argv, @"ClockApplication", @"ClockApplication");
    [p drain];
    return ret;
}

这是我的ClockApplication.mm：

#import "RootViewController.h"

@interface ClockApplication: UIApplication <UIApplicationDelegate> {
    UIWindow *_window;
    RootViewController *_viewController;
}
@property (nonatomic, retain) UIWindow *window;
@end

@implementation ClockApplication
@synthesize window = _window;
- (void)applicationDidFinishLaunching:(UIApplication *)application {
    _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    _viewController = [[RootViewController alloc] init];
    [_window addSubview:_viewController.view];
    [_window makeKeyAndVisible];
}

- (void)dealloc {
    [_viewController release];
    [_window release];
    [super dealloc];
}
@end

Answer 1

尝试从此

更改您的方法

-(NSInteger)supportedInterfaceOrientations:(UIWindow *)window{
}

到这个

-(NSUInteger)supportedInterfaceOrientations{
}

修改

尝试在这样的导航控制器中调用您的视图：

UIViewController *yourViewController = [[UIViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:yourViewController];
nc.navigationBarHidden = YES;
[self.navigationController presentModalViewController:nc animated:NO];
[self.navigationController dismissModalViewControllerAnimated:NO];

修改

#import "RootViewController.h" @interface ClockApplication: UIApplication <UIApplicationDelegate> { UIWindow *_window; RootViewController *_viewController; } @property (nonatomic, retain) UIWindow *window; @end @implementation ClockApplication @synthesize window = _window; - (void)applicationDidFinishLaunching:(UIApplication *)application { _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:_viewController]; nc.navigationBarHidden = YES; _window.rootViewController = nc; [_window makeKeyAndVisible]; } - (void)dealloc { [_viewController release]; [_window release]; [super dealloc]; } @end

Answer 2

尝试添加：

_window.rootViewController = _viewController;

编辑：无论如何，您的代码看起来像使用“已弃用”的样式。我建议为iOS6设置一个新项目并使用它的模板。它在iOS5上运行但iOS发生了变化。

Answer 3

只有rootViewController的{{1}}才会收到轮换事件。

UIWindow
