iOS 6 orientation issues - orientation

Question

I have an application which normally is a portrait app and only show landscape view for one UIViewController. It works fine until the new iOS 6 is released.
I really don't understand how orientation works in iOS 6. So I wrote a testing app. Here is what I did:
Set the orientation of the application to support all orientations.
I'm using story board. The rootViewController is embedded in UINavigationController which is in portrait.
The code in rootViewController:
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
When I clicked the Open bar button, I'll push another (SecondViewController) view controller which supposed to be in landscape mode:
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
Although this method is called correctly, the second view controller is always also in portrait mode.
Can anybody give me some suggestions? Thanks

Answer 1

Here is my solution:
In second view controller's viewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
UIViewController *viewController = [[UIViewController alloc] init];
[self presentViewController:viewController animated:NO completion:^{
[viewController dismissViewControllerAnimated:NO completion:nil];
}];
}
This will force the second view to rotate to landscape orientation which solved my problem. And it works for iOS 5 and 6.

Answer 2

For iOS-6, I have done this. It is running fine
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft;}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationLandscapeLeft;}
In second View
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return YES;}

Answer 3

I think that best solution is to stick to official apple documentation. So according to that I use following methods and everything is working very well on iOS 5 and 6.
In all of your ViewControllers override following methods.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
Methods for iOS 6, first method returns supported orientation mask (as their name indicate), you can change it into Landscape or what suites you best.
-(NSInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait; //UIInterfaceOrientationMaskPortrait or LandscapeLeft ...
}
second one thats tells your VC which is preferred interface orientation when VC is going to be displayed.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait; //tells your VC in which orientation it should be presented, if you set Porttrait it would be in Portrait or otherwise ...
}
This solution is working smooth, I dont like the idea of creating macros and other stuffs, that goes around this simple solution.
Hope this help...
