뷰가 전환되면 tabBar가 사라집니다. 왜?

Question

모두.

두 개의보기 (ScrollView 및 TableView)로 앱 TabBar를 만들고 있습니다.

응용 프로그램이 시작되면 TabBar 단추가 나타나고 두 개의보기를 변경할 수 있습니다.

TableView에서 누름 단추를 프로그래밍하여 ScrollView를 변경하면보기가 변경됩니다. 하지만 TabBar가 사라집니다.

누군가 도와주세요! 조언 해줘.

Answer 1

당신은 모달보기로 제시하고 있습니다. 귀하의 질문을 이해하면 UITabBar에서 선택한 항목을 전환하기 만하면됩니다. 당신이 좋아하는 작업을 수행 할 수 있습니다

인덱스 전환하려는 UIViewController의 인덱스를 나타내는 정수입니다

self.tabBarController.selectedIndex = index; 

. 귀하의 경우 인덱스는 0이어야합니다.
