与此代码：
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ([elementName isEqualToString:@"item"]) {
isBlogPost = YES;
}
if ([elementName isEqualToString:@"title"] && isBlogPost == YES) {
NSString *reviewName = [NSString stringWithFormat:@"%@",[attributeDict objectForKey:elementName]];
NSLog(@"%@",reviewName);
}
}
然而NSLogs正在返回零。这是为什么发生？对不起，如果这是一个愚蠢的问题，但我从来没有解析XML。
非常感谢！再次为这个愚蠢的问题感到抱歉。 –
