当用户按下搜索按钮时,UISeachBar会检测到

Question

我尝试Search在键盘中单击按钮时收到通知UISearchBar:

    - (BOOL)textFieldShouldReturn:(UITextField *)textField{

        return YES;
    }

但是当我按下"搜索"按钮时,此方法不会调用.

Answer 1

你试过这个代表吗？

Objective-C的:

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar

迅速:

func searchBarSearchButtonClicked(searchBar: UISearchBar)

请参阅任何搜索栏代表的文档. https://developer.apple.com/documentation/uikit/uisearchbardelegate
