I am using iOS 6.0 beta and my rotations do not work anymore.
Where can I set a UINavigationControllers supportedOrientations?
According to this http://news.yahoo.com/apple-ios-6-beta-3-changes-182849903.html a UINavigation Controller does not consult their children to determine whether they should autorotate.
I am not using shouldAutorotateToInterfaceOrientation: anymore as it is deprecated. Instead I am using supportedInterfaceOrientations: and shouldAutoRotate: and they are working fine until I place a ViewController into a NavigationController (as a Child). From then on the orientations specified in the ViewController do not work anymore. It seems it is using the orientations set by the navigation controller (UIInterfaceOrientationMaskAllButUpsideDown)
How can I set the InterfaceOrientations for the NavigationController so that my ViewControllers are locked to Portrait-Orientation?
Do I have to subclass UINavigationController and set the InterfaceOrientations there? Isn't it bad practise to subclass UINavigationController still in iOS 6.0?
Thanks for you help heaps!
Cheers!
If you want it to consult it's children again you can add a category to UINavigationController
@implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
@end
Subclass UINavigationController
//OnlyPortraitNavigationController.h
@interface OnlyPortraitNavigationController : UINavigationController
//OnlyPortraitNavigationController.m
@implementation OnlyPortraitNavigationController
- (BOOL)shouldAutorotate {
return NO;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait; //for locked only Portrait
}
present new subclass navigationController with your portrait ViewController
SomeViewController *onlyPortraitVC = [[SomeViewController alloc]init];
OnlyPortraitNavigationController *portraitNav = [[OnlyPortraitNavigationController alloc]initWithRootViewController:onlyPortraitViewController];
[self presentViewController:portraitNav animated:YES completion:NULL];
this is work on my app hope it can help you.
