Objective c 更改smjobbless对话框KauthorizationEnvironment提示符的文本

SMJobBless有一个对话框提示，告诉用户它正在安装帮助工具，并键入密码继续。我想更改文本

下面的代码没有更改文本，而是将我的自定义文本放在开头，并且仍然显示默认文本。我错过了什么或做错了什么

// Creating auth item to bless helper tool and install framework
AuthorizationItem authItem = {kSMRightBlessPrivilegedHelper, 0, NULL, 0};

// Creating a set of authorization rights
AuthorizationRights authRights = {1, &authItem};

NSString *promptText = @"Customized Text. Privilege?\n\n";

AuthorizationItem dialogConfiguration[1] = { kAuthorizationEnvironmentPrompt, [promptText length], (char *) [promptText UTF8String], 0 };

AuthorizationEnvironment authorizationEnvironment = { 0 };
authorizationEnvironment.items = dialogConfiguration;
authorizationEnvironment.count = 1;

// Specifying authorization options for authorization
AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagInteractionAllowed | kAuthorizationFlagExtendRights;

// Open dialog and prompt user for password
OSStatus status = AuthorizationCreate(&authRights, &authorizationEnvironment, flags, authRef);`

使用kAuthorizationRightExecute而不是kSMRightBlessPrivilegedHelper将获得一个只要求输入密码的短文本。。并使用kAuthorizationEnvironmentPrompt，因为环境可以在提示的开头添加其他文本
