ios - 如何在 iPhone 应用程序的 url 中传递一个字符串值？

Question

我有这个 URL 我想在这个 url cid=self.Id 中传递 Self.Id 。我明白为什么但是获取结果无效请求。

    NSURL *url = [NSURL URLWithString: 
    @"http://sms.instatalkcommunications.com/apireq/GetCommentsForSMS?
     t=1&h=admin&last=0&cid=Self.Id&items=5"];
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setRequestMethod:@"GET"];
   [request setDidFailSelector:@selector(requestCompleted:)];
   [request setDelegate:self];
   [request startAsynchronous];

[NSURL URLWithString:[NSString stringWithFormat:@"http://sms.instatalkcommunications.com/apireq/GetCommentsForSMS?
     t=1&h=admin&last=0&cid=%@&items=5",Self.Id]];
