iPad上的UIModalPresentationFormSheet - 隐藏状态栏

Question

任何想法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

你可以隐藏导航栏抛出导航控制器。 例如使用：

[infoViewNavController setNavigationBarHidden:YES animated:NO]; 

凡infoViewNavController是导航控制器，将保留您的模态演示的viewController。

假设你像这样调用它：

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];
