활성 상태 일 때 SearchBar가 이동합니다.

Question

SegmentedControl, UITableView 및 UISearchController가있는 UIViewController가 있습니다. SegmentedControl은 tableView 바로 아래에있는 기본 뷰의 맨 위에 있습니다. searchController의 검색 창은이 같은 tableView.tableHeaderView에 놓고 본다된다

검색 창은 (활성 제) 도청

그냥 위의 격차를 떠나 아래로 이동 :

또한 searchBar가 활성화되어 있고 segmentedConrol이 탭되면 (테이블 데이터를 필터링하고 tableView를 다시로드하는 경우) tableView가로드되지만 맨 위에는 간격이 있습니다. (나는 일부러 '카테고리'필터를 선택하면 숨겨진에 검색 창을 설정했습니다.

을 segmentedControl '카테고리는'검색 창은이 보이는 어떻게 활성화되지 않은 경우 선택 (봐해야하는 경우) :

내가 두 가지 (나는 그들이 관련되어 생각), 액티브 1) 검색 창 이동하지하는과 '분류'를 할 때 2) 검색 창은 존재하지 할 필요가 선택된다 tableView 맨 위에 간격이 있어야합니다.

당신이 활성 때 너무 searchBar 항상 이동합니다 UISearchController을 사용하기 때문에. 이를 피하려면 UISearchBar을 사용하십시오. UISearchBar을 사용하면 선택시 숨기기가 쉽습니다. Category tab
