             }
             else
             {
                 msg = [NSString stringWithFormat:NSLocalizedString(@"EVALUATE_POLICY_WITH_ERROR", nil), authenticationError.localizedDescription];
             }
         }];
     }

推荐答案

隐藏按钮输入密码，您需要将 localizedFallbackTitle 设置为空字符串。

To hide the button "Enter password", you need to set localizedFallbackTitle to an empty string.

//...
LAContext *context = [[LAContext alloc] init];

// Hide "Enter Password" button
context.localizedFallbackTitle = @"";

// show the authentication UI
//...

关于取消按钮我不认为可以删除它。

About the "Cancel" button I don't think that it is possible to remove it.
