iOS App UIView rotating, content is not - ios

Question

I'm currently building an iOS app, and the only supported orientations are landscape left and right. I've specified this in several ways:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return UIInterfaceOrientationIsLandscape(toInterfaceOrientation); //iOS 5 compatibility.
}
-(NSInteger)supportedInterfaceOrientations:(UIWindow *)window{
return UIInterfaceOrientationMaskLandscape; //iOS 6
}
-(BOOL)shouldAutorotate{
return YES;
}
And I've specified the supported orientations as only the landscape ones in the app's Info.plist. When I run the app on my device (or even in the simulator), I know that the root view is in landscape orientation (switcher is on the long side of the screen, as is notification center), however the content still originates from the top left corner of the screen, as if in portrait mode, not the bottom left or top right, like I want it to be. I have no idea what could be causing the content not to rotate with the parent view, as this code worked on iOS 5, but is not on iOS 6.
EDIT: Here's a screenshot.
EDIT: Here's my 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;
}
And here's my 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

Try changing your method from this
-(NSInteger)supportedInterfaceOrientations:(UIWindow *)window{
}
to this
-(NSUInteger)supportedInterfaceOrientations{
}
EDIT
Try calling your view inside a navigationcontroller like this:
UIViewController *yourViewController = [[UIViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:yourViewController];
nc.navigationBarHidden = YES;
[self.navigationController presentModalViewController:nc animated:NO];
[self.navigationController dismissModalViewControllerAnimated:NO];
EDIT
#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

Try to add:
_window.rootViewController = _viewController;
EDIT: Anyway your code looks like using "deprecated" style. I would suggest to set up a new project for iOS6 and use its template. It was working on iOS5 but iOS changes.

Answer 3

Only the rootViewController of your UIWindow will receive rotation events.
[_window setRootViewController:_rootViewController];
