标签内的MWFeedParser标签(媒体:缩略图)

Question

我正在使用MWFeedParser从这里读取Youtube atom提要：here

Xml代码：

 <media:thumbnail url='http://i.ytimg.com/vi/7_1PfqGVSg0/0.jpg' height='240' width='320' time='00:01:34.500'/>

如何获取媒体的url :缩略图？我尝试在MWFeedParser.m中进行如下更改：

else if ([currentPath isEqualToString:@"/feed/entry/link"]) { [self processAtomLink:currentElementAttributes andAddToMWObject:item]; processed = YES; }

要这样做：

else if ([currentPath isEqualToString:@"/feed/entry/media:thumbnail"]) { [self processAtomLink:currentElementAttributes andAddToMWObject:item]; processed = YES; }

但是它不工作:(

在case FeedTypeAtom一节中添加以下代码：

else if ([currentPath isEqualToString:@"/feed/entry/media:group/media:thumbnail"]) {
    NSString *urlString = [currentElementAttributes objectForKey:@"url"];                   
    if ( urlString != nil && urlString.length > 0) 
        item.thumbnail = urlString;  
    processed = YES;
}

还要向MWFeedItem对象添加NSString *缩略图属性
