我在使用内置 iOS JSON 解析器解析 Twitter 搜索结果时遇到问题。
NSDictionary *resultorig = [NSJSONSerialization JSONObjectWithData:self.responseData options: NSJSONReadingMutableContainers error: &err];
NSMutableArray *result = [resultorig objectForKey:@"results"];
NSLog(@"%@", result);
我正在使用此网址搜索 Twitter：http ://search.twitter.com/search.json?q=%23xbox
其中打印出：

我正在尝试在 tableview 的每一行中显示推文文本，但它与我当前的代码崩溃：
NSDictionary *aTweet = [result objectAtIndex:indexPath.row];
cell.theTweet.text = [aTweet objectForKey:@"text"];
NSLog(@"%@", [aTweet objectForKey:@"text"]);
我究竟做错了什么？任何帮助将不胜感激，因为我几乎整天都在尝试修复此崩溃。谢谢。
