이보기 컨트롤러는 UItabViewController에 포함 된 여러보기 컨트롤러 중 하나입니다. 이 viewController의 탭을 처음 선택하면 모든 것이 잘 작동하고 데이터 소스는 getOrdersByCustomer()에서 업데이트되며 모든 주문 셀이 표시됩니다. 그러나 다른보기 컨트롤러 (다른 탭)에서 주문을 가져 와서 self.tabBarController? .selectedIndex = 2를 사용하여이보기 컨트롤러로 다시 이동하면 다른보기 컨트롤러에서 배치 된 새 주문에 대한 JSON이 표시됩니다. 이 새로운 주문을위한 셀이 나타나지 않습니다.UItableView가 데이터를 다시로드하지 않음
viewWillAppear에서 다음 메서드를 호출하면 데이터 소스가 업데이트되고 있지만 self.tableView.reloadData()가 작동하지 않는 것 같고 새로 배치 된 순서의 셀이 표시되지 않습니다. 다른 뷰 컨트롤러

self.tableView가 올바른 테이블 뷰인지 확인할 수 있습니까? 만약 당신이 저장하기 전에 'tableView (_ tableView : UITableView, numberOfRowsInSection 섹션 : Int) -> Int'에 중단 점을 추가하고 함수가 호출되는지 확인하기 위해 앱을 여는 -> 주문 추가 -> 시도 할 수 있습니다. 그것이 호출되면 그것은'getOrdersByCustomer()'와 관련된 문제이며, 그렇지 않으면 올바른 tableview를 새로 고치지 못할 수도 있습니다. 테이블 뷰는 처음 렌더링 될 때 자동으로 새로 고침되기 때문에 처음으로 작동합니다. –
