Question

所以，我在这里描述的问题上取得了一些进展 - https://stackoverflow.com/questions/27348458/svpulltorefresh-infinite-scroll-with-an-rss-feed

尽管如此，我有一个问题。该表最初加载了10个YouTube视频。然后，使用

加载第二个十

__weak MasterViewController *weakSelf = self;

[self.tableView addInfiniteScrollingWithActionHandler:^{

    NSLog(@"Infinite Scroll");
    [weakSelf updateVideoList];

}];

- （void）updateVideoList实际上将10个项添加到加载到表视图中的数组（在addObjectsFromArray将项添加到初始数组之后，最后在tableview上调用reloadData）。这很好用。问题是尝试加载第三个10项不起作用。我添加了NSLog以查看它是否第二次进入该方法，但它没有。

该方法是否有任何理由不能再次工作？

编辑这是updateVideoList，但是我使用日志来确定第二次调用该方法：

- (void) updateVideoList {

NSString *baseDomain = @"https://gdata.youtube.com/feeds/api/videos";
NSString *maxresults = @"10";
NSString *startIndex = [NSString stringWithFormat:@"%lu", (unsigned long)videoList.count+1];
NSString *orderBy = @"published";
NSString *author = @"theverge";
NSString *extension = @"v=2&alt=jsonc";
NSString *urlYoutube = [NSString stringWithFormat:@"%@?max-results=%@&start-index=%@&orderby=%@&author=%@&%@",
                        baseDomain,maxresults, startIndex,orderBy,author,extension];

NSDictionary *listOfVideos = [JSONParser listOfVideos:urlYoutube];
int videoListSize = [[[listOfVideos valueForKey:@"data"] valueForKey:@"totalItems"]  intValue];
if (videoListSize>0) {
    NSMutableArray *secondYoutubeList = [[NSMutableArray alloc] init];
    NSArray *arrayVideoList = [[listOfVideos valueForKey:@"data"] valueForKey:@"items"];
    for (NSDictionary *videoDictionary in arrayVideoList) {
        NSString *idVideo = [videoDictionary valueForKey:@"id"];
        NSString *description = [videoDictionary valueForKey:@"description"];
        //NSString *updated = [videoDictionary valueForKey:@"updated"];

        //            NSString *departTimeDate = [videoDictionary valueForKey:@"updated"];
        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"yyyy'-'MM'-'dd'T'HH':'mm':'ss'Z'"];
        //NSDate *date = [dateFormatter dateFromString:departTimeDate];

        NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:[NSDate date]];
        NSInteger day = [components day];
        NSInteger month = [components month];
        NSInteger year = [components year];

        NSString *updated = [NSString stringWithFormat:@"%ld, %ld, %ld", (long)month,(long)day,(long)year];

        NSString *duration = [videoDictionary valueForKey:@"duration"];

        NSString *title = [videoDictionary valueForKey:@"title"];

        // If we are using wifi, take hqDefault
        NSString *thumbnail = [[videoDictionary valueForKey:@"thumbnail"] valueForKey:@"hqDefault"];
        YoutubeVideo *video = [[YoutubeVideo alloc] initWithId:idVideo withDescription:description withUpdated:updated withDuration:duration withTitle:title withThumbnail:thumbnail];
        [secondYoutubeList addObject:video];

    }
    [videoList addObjectsFromArray:secondYoutubeList];
    [self.tableView reloadData];
}
}

你应该致电

[self.tableView.infiniteScrollingView stopAnimating];

完成重装工作后。
