iOS 는 UISearchController 를 사용 하여 애니메이션 문 제 를 해결 합 니 다.

첫 번 째 단계:searchBar Should BeginEditing 을 통 해 해결 하고 편집 할 때 cancel 글꼴 문제:

func searchBarShouldBeginEditing(_ searchBar: UISearchBar) -> Bool {
        searchCurrentPage = 1
        searchListArray = listArray
        tableView.reloadData()
        
        searchBar.setShowsCancelButton(true, animated: true);
        let tempView = searchBar.subviews.first;
        for subView: UIView in (tempView?.subviews)!{
            if subView.isMember(of: NSClassFromString("UINavigationButton")!){
                let cancelButton: UIButton = subView as! UIButton;
                cancelButton.setTitle("  ", for: .normal);
                break;
            }
        }
        
        return true
    }

두 번 째 단계:searchBarSearchButton Clicked 를 통 해 검색 을 클릭 하여 네트워크 요청 을 수행 합 니 다.

func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
        if searchListArray.count > 0 {
            searchListArray.removeAll()
        }
        
        //       ，      
        self.tableView.reloadData()
    }

세 번 째 단계:검색 BarCancelButton Clicked 를 통 해 검색 상태 취소

func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
        searchController.isActive = false
        self.tableView.reloadData()
    }

네 번 째 단계:검색 상자,팝 업,사라 질 때 애니메이션 이 동기 화 되 지 않 는 문 제 를 해결 합 니 다.

func willPresentSearchController(_ searchController: UISearchController) {
        self.edgesForExtendedLayout = .bottom
    }
    func willDismissSearchController(_ searchController: UISearchController) {
        self.edgesForExtendedLayout = .bottom

    }
