iOS NSXMLPARSER在RSS Feed中解析媒体内容标记

I am using NSXMLParser to parse RSS feed. Earlier i was using the image url from cdata block but now i have come across a feed that has the image url inside

我正在使用NSXMLParser来解析RSS提要。早些时候我正在使用来自cdata块的图片网址，但现在我遇到了一个内部有图片网址的Feed

<media:content url="http://cdn.example.com/wp-content/uploads/2013/10/article-2462931-18C5CBC000000578-776_634x452.jpg" medium="image"/>

How do i pick the image url from this tag? This is what i am trying to use inside didStartElement method but its not working:

如何从此标记中选择图像网址？这是我想在didStartElement方法中使用但它无法正常工作：

if ([elementName isEqual:@"media:content"])
    {
        currentString = [[NSMutableString alloc] init];

        // Basically i need the image url string at this point             

        NSString *imageURLString = [self getFirstImageUrl:currentString];
        imageURL = [NSURL URLWithString:imageURLString];
        [self downloadThumbnails:imageURL];
    }

How can i pick the image url string from the media content tag? Thanks!

In didStartElement method of NSXMLParser, i wrote the following:

在NSXMLParser的didStartElement方法中，我写了以下内容：

if ([elementName isEqual:@"media:content"])
    {
        NSString *imageURLString = [attributeDict objectForKey:@"url"];
        NSLog(@"imgURL %@",imageURLString);

        // Here you can use the imageURLString to download the image
    }
