iphone - 全屏模式视图无法在 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];

当前的模态视图在设备旋转时无法旋转。如果我更改modalPresentationStyle为UIModalPresentationFormSheet，它的工作原理！

HDComposeViewController 已经实现了旋转委托：

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

- (BOOL)shouldAutorotate
{
    return YES;
}

有什么不对的吗？谢谢。

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才能在 ios 6 中旋转。

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

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