無法停止搜索欄顯示取消按鈕

Question

因此，當我單擊搜索欄時，我試圖阻止取消按鈕的出現。 我已經試過了-

[self.searchDisplayController.searchBar setShowsCancelButton: NO animated:NO];
NSLog(@"CANCEL BUTTON : %hhd", self.searchDisplayController.searchBar.showsCancelButton);

日志告訴我showsCancelButton的值為0 ，表明它已關閉。

發生什么了？

Answer 1

您只需在“ searchDisplayControllerWillBeginSearch”委托方法中將取消按鈕設置為隱藏即可，例如：

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
    controller.searchBar.showsCancelButton = NO;
}

如果您不使用UISearchDisplayController，也可以在下面使用

-(void) searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
    //This'll Show The cancelButton with Animation
    [searchBar setShowsCancelButton:NO animated:YES];
}

Answer 2

嘗試這個，

    - (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar {
        searchBar.showsCancelButton = NO;
        return YES;
    }
