UITableView+YouTubeAPI解析JSON响应以进行统计

Question

我正在从youtube API v3获得JSON响应https://www.googleapis.com/youtube/v3/channels?part=statistics&id并接收JSON响应作为

{
etag = ""rFqCJSkEICLP3Hq6a4AADI7kf48/2zirKmd0WgUqY0RzlyD4hlACeWM"";
items =     (
            {
        etag = ""rFqCJSkEICLP3Hq6a4AADI7kf48/u4TmQ5XfIQQg6y6u4Od2yULCVlc"";
        id = "HCcrj0EHvn_Y8";
        kind = "youtube#channel";
        statistics =             {
            commentCount = 0;
            subscriberCount = 21694;
            videoCount = 124582;
            viewCount = 0;
        };
    },
            {
        etag = ""rFqCJSkEICLP3Hq6a4AADI7kf48/2p4_mjrZLfhO6bDvH-RgAykNQr8"";
        id = UCX2v47KsDKqajrEYFV7GbBg;
        kind = "youtube#channel";
        statistics =             {
            commentCount = 6460;
            subscriberCount = 494656;
            videoCount = 33;
            viewCount = 713607227;
        };
    }

}

当我试图显示时

cell.viewsChannel.text=[[_statistics valueForKeyPath:@"statistics.videoCount"] objectAtIndex:indexPath.row];

该值不会显示在表视图中。我试图将输出格式化为unsigned long，int，但没有显示正确的值。请帮忙提前感谢

我认为您需要将项添加到valueForKeyPath

cell.viewsChannel.text=[[_statistics valueForKeyPath:@"item.statistics.videoCount"] objectAtIndex:indexPath.row];
