FullScreen模式视图无法在iPad iOS 6上旋转

Question

代码：

HDComposeViewController *vc = [[HDComposeViewController alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
nav.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentModalViewController:nav animated:YES];

当设备旋转时，当前模态视图无法旋转。如果我将modalPresentationStyle更改为UIModalPresentationFormSheet，则会有效！

HDComposeViewController已经实现了旋转委托：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;
}

- (BOOL)shouldAutorotate
{
    return YES;
}

有什么不对吗？感谢。

Answer 1

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
    }

-(BOOL)shouldAutorotate
{
    return YES;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

Answer 2

您需要为导航控制器添加一个类别，以便在ios 6中旋转。

@interface UINavigationController (RotationAll)
    -(NSUInteger)supportedInterfaceOrientations;
@end

@implementation UINavigationController (RotationAll)
-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}
@end
