旋转后更改 modalPresentationStyle

Question

我需要帮助解决问题。我想在旋转事件后打开时动态更改 modalPresentationStyle。 我写这个是为了创建 modalView

 ZUITableViewController *ivc = [[ZUITableViewController alloc] init];
    ivc.delegate = self;
    _modalIsShowing = TRUE;
    UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:ivc];
    if (UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
    {
        nc.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
        nc.modalPresentationStyle = UIModalPresentationFormSheet;

    }
    else{
        nc.modalPresentationStyle = UIModalPresentationFullScreen;
    }
    [self presentModalViewController:nc animated:YES];
    [ivc release];
    [nc release];

Answer 1

废弃 if 语句 UIModalPresentationPageSheet 行为正常。

ZUITableViewController *ivc = [[ZUITableViewController alloc] init];
ivc.delegate = self;
_modalIsShowing = TRUE;
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:ivc];
nc.modalPresentationStyle = UIModalPresentationPageSheet;
[self presentModalViewController:nc animated:YES];
[ivc release];
[nc release];
