iPad上的UIModalPresentationFormSheet - 隱藏狀態欄

Question

任何想法爲什麼當模態控制器在iPad上顯示爲UIModalPresentationFormSheet時無法隱藏狀態欄？ 覆蓋preferedStatusBarHidden不起作用

Answer 1

你可以隱藏導航欄拋出導航控制器。 例如使用：

[infoViewNavController setNavigationBarHidden:YES animated:NO]; 

凡infoViewNavController是導航控制器，將保留您的模態演示的viewController。

假設你像這樣調用它：

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];
