我不太确定我在这里做错了什么，我已经按照教程进行了操作。这是我的问题，我有一本名为 dict 的字典，它是 TWRequest 的结果 - 由于我的日志详细信息，我知道它包含推文。我现在正在尝试创建一个包含“文本”元素的数组，但我的日志显示该数组为空白？？！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];

对我来说，您的dict字典中似乎没有关键的“文本” 。但是你有关键的结果。如果你执行

NSArray results = [dict objectForKey:@"results"];

你会得到包含 NSDictionaries 的 NSArray。那些嵌套字典有关键的“文本”。所以你需要遍历数组结果：

NSMutableArray *allTweetText = [NSMutableArray array];

for (NSDictionary *result in results) {
    NSString *text = [result objectForKey:@"text"];
    [allTweetText addObject:text];
}
