这段代码会对你有帮助。

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
  [responseData setLength:0];
 }

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
 [connection release];
 self.responseData = nil;
 }

 - (void)connectionDidFinishLoading:(NSURLConnection *)connection {
  [connection release];


  NSLog(@"Response String= %@",responseString);  //response string is ur  JSON Array value

    NSArray* latestLoans = [(NSDictionary*)[responseString JSONValue] objectForKey:@"comments"];
 NSLog(@"Lateste = %@",latestLoans);

 [responseString release];
 NSDictionary* loan = [latestLoans objectAtIndex:0];
 NSString* number1 = [loan objectForKey:@"comment"];
 NSString* firstName = [loan objectForKey:@"created_at"];
 NSString* emails = [loan objectForKey:@"user"];

 NSLog(@"number1= %@,  firstName= %@  Emails= %@",number1,firstName,emails);
  }
