一度セグメンテーションされたUISearchBarを解除する方法

Question

検索ビューを作成すると、これはメイン検索ビューで行ったコードです。

検索/フィルタを使用しないと、セグメンテーション時にuisearchbarが終了します。しかし、もし私が検索/フィルタリングすると、uisearchbarはseguing時にnav barにとどまります。あなたのAirlineTableViewControllerで

     [super viewDidLoad];

、[のUIViewController prepareForSegue]をオーバーライドします。

- (void)prepareForSegue:(UIStoryboardSegue *)segue 
       sender:(id)sender { 
[self.searchController setActive:NO]; 
}
