我的代碼，它在你正在尋找didStartElement（其中初始化currentNodeContent）不匹配的元素名稱media:description

- (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

元素的名稱，你正在使用您的didEndElement方法保存並重置currentNodeContent。

因此，你的臺詞是說：

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

也許應該說：

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