Answer 1

好的我搞清楚了......

在idStartElement回调中，我添加了代码：

if（[elementName isEqualToString：@“link”]）{
  的NSString   * string = [attributeDict objectForKey：@“href”];
  NSLog（@“Link is％@”，string）;
  [currentLink appendString：[self cleanURL：string]];   }

 - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
//NSLog(@"found this element: %@", elementName);

    if ( [elementName isEqualToString:@"link"]) {
        if([[attributeDict objectForKey:@"rel"] isEqualToString:@"alternate"]){
            NSString *string = [attributeDict objectForKey:@"href"];
            NSString *titulo = [attributeDict objectForKey:@"title"];
            NSLog(@"Link is %@ ", string);
            NSLog(@"titulo is %@ ", titulo);
            //[currentLink appendString:[self cleanURL:string]];
        }
    }

    if ( [elementName isEqualToString:@"media:thumbnail"]) {
        NSString *url = [attributeDict objectForKey:@"url"];
        NSLog(@"url is %@ ", url);
    }

}
