我的代码在media:description 中

- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    if ([elementname isEqualToString:@"title"] || [elementname isEqualToString:@"content"])
    {
        currentNodeContent = [[NSMutableString alloc] init];
    }
    else if ([elementname isEqualToString:@"entry"])
    {
        currentFeed = [ChanelFeeds alloc];
    }
    else if ([elementname isEqualToString:@"yt:duration"])
    {
        currentFeed.duration = [attributeDict objectForKey:@"seconds"];
    }
    else if ([elementname isEqualToString:@"yt:statistics"])
    {
        currentFeed.views = [attributeDict objectForKey:@"viewCount"];
    }
    else if ([elementname isEqualToString:@"gd:rating"])
    {
        currentFeed.rating = [attributeDict objectForKey:@"average"];
    }
    else if ([elementname isEqualToString:@"media:player"])
    {
        currentFeed.streamURL = [NSURL URLWithString:[attributeDict objectForKey:@"url"]];
    }
    else if ([elementname isEqualToString:@"media:thumbnail"] && !currentFeed.thumbnailURL)
    {
        currentFeed.thumbnailURL = [NSURL URLWithString:[attributeDict objectForKey:@"url"]];
    }
}
- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
    if ([elementname isEqualToString:@"title"])
    {
        currentFeed.title = currentNodeContent;
        currentNodeContent = nil;
    }
    else if ([elementname isEqualToString:@"media:description"])
    {
        currentFeed.description = currentNodeContent;
        currentNodeContent = nil;
    }
    else if ([elementname isEqualToString:@"entry"])
    {
        [self.feeds addObject:currentFeed];
        currentFeed = nil;
        currentNodeContent = nil;
    }
}

Answer 1

您在didStartElement（初始化currentNodeContent）中查找的元素名称与您用于在didEndElement方法中保存和重置currentNodeContent的元素名称不匹配。

因此，你的行说：

if ([elementname isEqualToString:@"title"] || [elementname isEqualToString:@"content"])
{
    currentNodeContent = [[NSMutableString alloc] init];
}

可能应该说：

if ([elementname isEqualToString:@"title"] || [elementname isEqualToString:@"media:description"])
{
    currentNodeContent = [[NSMutableString alloc] init];
}
