iPad上的UIModalPresentationFormSheet - 隐藏状态栏

Question

知道为什么当模态控制器在iPad上显示为UIModalPresentationFormSheet时，无法隐藏状态栏？ 覆盖preferedStatusBarHidden不起作用

Answer 1

您可以隐藏导航栏以抛出导航控制器。 例如使用：

[infoViewNavController setNavigationBarHidden:YES animated:NO];

infoViewNavController 是导航控制器，它将保存用于模态演示的viewController。

假设你这样称呼它：

 UINavigationController *infoViewNavController =
        [[UINavigationController alloc] initWithRootViewController:viewControllerToShow];

infoViewNavController.modalPresentationStyle = UIModalPresentationFormSheet;
infoViewNavController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[infoViewNavController setNavigationBarHidden:YES animated:NO];

self.navigationController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
self.navigationController .modalPresentationStyle = UIModalPresentationFormSheet;
[self.navigationController  presentViewController:infoViewNavController animated:YES completion:nil];
