Answer 1

상태 표시 줄과 탐색 모음을 동시에 숨기면이 문제가 발생할 수 있습니다. 나는 심지어 0 지연을 가지고 performSelector:withObject:afterDelay으로 내비게이션 막대를 숨기거나 표시함으로써이를 해결할 수있었습니다.

Answer 2

는 귀하의보기가 너무 크게 설정되어있다. Interface Builder를 사용하여 .xib로 만들려면 "Simulated Interface Elements"아래의 상태 표시 줄에 대한 설정을 활성화하거나 수동으로보기 높이를 줄여야합니다.

Answer 3

"performSelector"를 사용하면 효과가 있습니다.

그러나 일부는 탐색 모음을 숨김 해제하는 명령문이 이미있는 경우에도 "viewWillDisappear"에 다음을 추가하는 것이 더 쉽습니다. 그것을하지

[self.navigationController setNavigationBarHidden:YES animated:NO]; 
[self.navigationController setNavigationBarHidden:NO animated:NO];
