嘿我正在使用NSURL连接来接收数据.

[NSURLConnection sendSynchronousRequest:
//create request from url
[NSURLRequest requestWithURL:
  //create url from string
  [NSURL URLWithString:url]
] 
//request parameters
returningResponse:nil error:nil
] 

是否可以更改用户代理字符串？现在它是:

AppName/AppVersion CFNetwork/459 Darwin/10.0.0.d3
