Swift TableView scrollsToTop

Question

사용자가 탭 막대를 탭하면 tableView가 맨 위로 스크롤되도록하고 싶습니다.

self.tableView.scrollsToTop = true 

을했지만 작동하지 않습니다

내가있는 viewDidLoad 방법에 설정합니다.

다른 스크롤보기가 없습니다. 내 viewController 경우에만이 tableView 포함되어 있습니다.

나는이 시도했지만 작동하지 :

override func scrollViewShouldScrollToTop(scrollView: UIScrollView) -> Bool { 
    if scrollView == self.tableView { 
     return true 
    } 

    else { 
     return false 

    } 
}
