如何在没有用户的情况下将服务器授权到iOS应用程序？
我是如何在没有用户的情况下将服务器授权到iOS应用程序？,ios,objective-c,iphone,apache,authorization,Ios,Objective C,Iphone,Apache,Authorization,我是iOS编程新手。我制作了iOS应用程序，连接到MSSQL 当对服务器的联机对话框授权被停用时，它可以正常工作 因此，当我们激活授权时，我的应用程序无法工作。 如何在我的应用程序中指定授权数据？ 如何在应用程序中填写登录和传递背景信息？ 它是否安全 我的代码是下一个： ViewController.m 下一个错误是： 2016-01-25 17:10:50.398报告[751:22264]响应：{URL:https://*****/file.php}{状态代码：401，标题{ 连接=关闭；

401需要授权
你的问题不太清楚，我不知道如何在应用程序中填写和传输登录信息，并将数据传递到服务器后台。这取决于你如何配置服务器。通常我们使用基本访问身份验证
，我们将其放入header@YHaiti我们进行了基本的访问验证，但应用程序无法运行。我尝试使用凭据执行NSURLSession，但401仍然出现：（@Maria你能分享你的代码吗？这样我们就可以知道你如何使用NSURLSession了。你的问题不太清楚。我不知道如何在应用程序中填写和传输登录信息，以及将数据传递到服务器后台。这取决于你如何配置服务器。通常我们使用我们放在header@YHaiti我们做了基本的空调cess身份验证，但应用程序不起作用。我尝试使用凭据执行NSURLSession，但401仍然显示：（@Maria你能分享你的代码吗？这样我们就可以看到你如何使用NSURLSession了
