NSDictionary转换为NSArray，然后返回NSDictionary

Question

我正在尝试在UITableView中显示来自disqus.com的评论。

现在我有：1。

//Creating NSArray with comments only from NSDictionary Dict
    comments = [dict objectForKey:@"response"];
            NSLog(@"MessageArray:%@ count:%i", comments, [comments count]);
            [tableViewNew reloadData];

2。

//I'm trying to get NSDictionary from NSArray, but it isn't work
NSDictionary *currentComment = [comments objectAtIndex:indexPath.row];
//currentComment = nil

在我的* .h文件中，我有这个：

NSArray* comments;
@property (retain, nonatomic) NSArray* comments;

和我的评论数组文本：

我想从阵列中获取所有密钥的NSDictionary。 非常感谢你。

Answer 1

您可以尝试以下一种方法：

    NSDictionary *currentComment = [[NSDictionary alloc] initWithDictionary: [comments objectAtIndex:indexPath.row]];

我认为您正在“ cellForRowAtIndex”方法中使用此方法...因此，如果是，则在此方法的最后将YES返回到单元格之前，请释放字典。 否则，可能会给您错误或错误的数据。.快乐编码：）
