iOS - 如何在UISearchBar中動畫（dis）範圍欄的動畫效果？

Question

嗯，我讀this文章，但範圍欄只顯示即時，沒有動畫。

Answer 1

這應該工作：

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar { 
    [searchBar setShowsCancelButton:YES animated:YES]; 
    searchBar.showsScopeBar = YES; 
    return YES; 
    } 

    - (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar { 
    [searchBar setShowsCancelButton:NO animated:YES]; 
    [searchBar sizeToFit]; 
    searchBar.showsScopeBar = NO; 
    return YES; 
    } 

記得到的UISearchBar委託關聯。
