如何使用objective-c和xcode从网站读取文件

I am trying to write a code that will grab some information provided by my server (remote), for example request a url that will return data that will be represented in the application after parsing it.

我正在编写一个代码，它将获取我的服务器(远程)提供的一些信息，例如请求一个url，该url将返回解析后在应用程序中表示的数据。

I've been trying since 2 days now I googled it i found some incomplete solution but nothing really worked out for me

我已经试了两天了，我在谷歌上搜了一下我找到了一些不完整的解决方案，但是没有什么对我有用

I am really noob in Xcode and Objective-C

我是Xcode和Objective-C的新手

Thanks

Click for the URL-Loading documentation provided by Apple. Especially Using NSURLConnection looks interesting for you.

点击苹果提供的url加载文档。尤其是使用NSURLConnection看起来很有趣。

Edit: Another very good and easy-to-use Framework for this task is ASIHTTP: Click

编辑:另一个非常好的、易于使用的框架是ASIHTTP:单击

The easiest way:

最简单的方法:

- (void)grabURL
{
  NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
  ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
  [request startSynchronous];
  NSError *error = [request error];
  if (!error) {
    NSString *response = [request responseString];
  }
}

Asynchronous loading is only slightly more complex:

异步加载只是稍微复杂一点:

- (void)grabURLInBackground
{
   NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
   ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setDelegate:self];
   [request startAsynchronous];
}

- (void)requestFinished:(ASIHTTPRequest *)request
{
   // Use when fetching text data
   NSString *responseString = [request responseString];

   // Use when fetching binary data
   NSData *responseData = [request responseData];
}

- (void)requestFailed:(ASIHTTPRequest *)request
{
   NSError *error = [request error];
}
