IPad UINavigationController景观问题

Question

我在横向模式下呈现UINavigationViewController时遇到问题。视图自动旋转为纵向模式。我已经花了大约3个小时来解决这个问题。如果我没有导航控制器，它工作正常。但是，我需要导航控制器，因为我必须从那推出另一个视图控制器。

请提出解决问题的建议。这是代码。

SharingViewController *sharingViewController = [[SharingViewController alloc] initWithNibName:@"SharingViewController" bundle:nil];

    UINavigationController *navi = [[[UINavigationController alloc] initWithRootViewController:sharingViewController] autorelease];

    [navi setWantsFullScreenLayout:YES];
    [navi.view setAutoresizesSubviews:NO];
    [navi.navigationBar setHidden:YES];
    navi.view.autoresizingMask = UIViewAutoresizingFlexibleWidth;
    navi.visibleViewController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth;

    self.modalPresentationStyle = UIModalPresentationCurrentContext;
    [self presentModalViewController:navi animated:YES];

Answer 1

如果你这样做：

SharingViewController *sharingViewController = [[SharingViewController alloc] initWithNibName:@"SharingViewController" bundle:nil];
sharingViewController.modalPresentationStyle = UIModalPresentationCurrentContext;

UINavigationController *navi = [[[UINavigationController alloc] initWithRootViewController:sharingViewController] autorelease];
navi.modalPresentationStyle = UIModalPresentationCurrentContext;
...

[[self navigationController] presentModalViewController:navi animated:YES];

它应该有用。我有同样的问题，但当我将 modalPresentationStyle 属性添加到viewController和UINavigationController时，它开始工作。
