Basic HTTP Authentication using Obj C and Xcode
提问by Kristiaan
I am hoping someone can help me with a question i have relating to Basic HTTP Authentication in an Xcode 2.3 application.
我希望有人可以帮助我解决与 Xcode 2.3 应用程序中的基本 HTTP 身份验证相关的问题。
Basically i have a PHP page that is on our server and when called with certain parameters returns data relating to the servers condition etc.
基本上我在我们的服务器上有一个 PHP 页面，当使用某些参数调用时，返回与服务器条件等相关的数据。
i have managed to get a small Xcode application working where by it reads the data from the page and populates an NSTextView with the data.
我设法让一个小的 Xcode 应用程序工作，它从页面读取数据并用数据填充 NSTextView。
however to make sure this information stays safe i have setup basic HTTP Authentication on the page, but i cannot work out how to provide the username and password in XCode.
但是为了确保这些信息保持安全，我在页面上设置了基本的 HTTP 身份验证，但我无法弄清楚如何在 XCode 中提供用户名和密码。
here is my code to retrieve the page.
这是我检索页面的代码。
NSURL *url = [NSURL URLWithString:@"http://www.google.com"];
NSString *content = [NSString stringWIthContentsOfUrl:url];
[myTextView setString:content];
i am still at a very basic beginner level regarding xcode and obj c, so nice simple examples of how i go about this would really be appreciated.
我仍然处于关于 xcode 和 obj c 的非常基本的初学者级别，因此非常感谢我如何进行此操作的简单示例。
Thanks Kris
