如何使用 NSMutableDictionary 解析图像？

Question

我需要帮助使用字典解析图像。我可以使用字典获取文本数据，但无法使用字典解析相应内容的图像，这里是我的代码

   -(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
            currentElement = [elementName copy];
           if ([elementName isEqualToString:@"title"]) {
                         item = [[NSMutableDictionary alloc] init];
                         ktitle = [[NSMutableString alloc] init];
                         kpubdate = [[NSMutableString alloc] init];
                         kitem = [[NSMutableString alloc] init];
                        //kmedia = [[UIImageView alloc] init];
                         klink = [[NSMutableString alloc] init];
                         kdescription = [[NSMutableString alloc] init];
                         }
          }
       -(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
          if ([elementName isEqualToString:@"title"]) {
                         [item setObject:ktitle forKey:@"title"];
                         [item setObject:klink forKey:@"link"];
                         [item setObject:kdescription forKey:@"description"];
                         [item setObject:kpubdate forKey:@"pubDate"];
                         //kmedia = [[UIImageView alloc] initWithImage:[UIImage           keyPathsForValuesAffectingValueForKey:@"media:content"]];
                         //[item setObject:kmedia forKey:@"media:content"];
                         [arrayList addObject:[item copy]];
                         }
          }
      -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
                if([currentElement isEqualToString:@"title"]){
                          [ktitle appendString:string];
                 }
                 else if ([currentElement isEqualToString:@"link"]) {
                           [klink appendString:string];
                 }
                 else if([currentElement isEqualToString:@"description"]){
                           [kdescription appendString:string];
                 }
       }
