我不太确定我在这里做错了什么，我已经把这些教程留给了这封信。这是我的问题，我有一个叫做dict的字典，它是TWRequest的结果 - 我知道它包含推文，因为我的日志细节。我现在正在尝试创建一个这个'text'元素的数组但是我的日志说数组的空白??！这是我的代码，任何帮助将不胜感激。谢谢
NSArray *allTweetText = [dict objectForKey:@"text"];
NSLog(@"WHERE IS THIS: %@", allTweetText);
NSString *singleTweet = [allTweetText objectAtIndex:indexPath.row];
NSArray *parsedTweet = [singleTweet componentsSeparatedByString:@":"];
cell.myHeader.text = [parsedTweet objectAtIndex:0];
cell.myDetails.text = [parsedTweet objectAtIndex:1];
cell.myDate.text = [parsedTweet objectAtIndex:2];

2012-06-16 06:49:38.235 V4[560:207] WHERE IS THIS: (null)
答案 0 :(得分：1)
对我而言，您的 dict 字典中似乎没有关键字“text”。但是你有关键的结果。如果你执行
NSArray results = [dict objectForKey:@"results"];
你将获得包含NSDictionaries的NSArray。那些嵌套的词典有关键的“文本”。所以你需要迭代数组结果：
NSMutableArray *allTweetText = [NSMutableArray array];
for (NSDictionary *result in results) {
NSString *text = [result objectForKey:@"text"];
[allTweetText addObject:text];
}
