无法停止搜索栏显示取消按钮

Question

因此，当我单击搜索栏时，我试图阻止取消按钮的出现。 我已经试过了-

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

日志告诉我showsCancelButton的值为0 ，表明它已关闭。

发生什么了？

Answer 1

您只需在“ searchDisplayControllerWillBeginSearch”委托方法中将取消按钮设置为隐藏即可，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

尝试这个，

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