Question

我正在练习RESTKit，所以我正在构建一个Dribbble客户端以获得REST的挂起，我成功地获得了XML响应，但是当我使用NSXMLParser解析它时，它会记录启动，然后立即停止，怎么能我修复它，或者只是简单地使用XML来整理哪个项目，然后将它放入我的表格中？

继承人代码：

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    NSLog(@"I just found a start tag for %@",elementName);

}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
    NSLog(@"the parser just found this text in a tag:%@",string);
}

-(void)parserDidStartDocument:(NSXMLParser *)parser {
    NSLog(@"starting");
}

-(void)parserDidEndDocument:(NSXMLParser *)parser {
    NSLog(@"end");
}

-(IBAction)test {
    [[RKClient sharedClient] get:@"/shots/popular" delegate:self];
}

-(void)request:(RKRequest *)request didLoadResponse:(RKResponse *)response {
    if ([request isGET]) {

        NSLog(@"Retrieved XML: %@", [response bodyAsString]);
        NSXMLParser *xmlParser = [[NSXMLParser alloc] initWithData:[response body]];
        [xmlParser setDelegate:self];
        [xmlParser parse];
    }
    else if ([request isPOST]) {


        if ([response isJSON]) {

            NSLog(@"Got a JSON response back from our POST!");
        }


    }
    else if ([request isDELETE]) {

        if ([response isNotFound]) {
            NSLog(@"The resource path '%@' was not found.", [request resourcePath]);
        }


    }
}

您从解析器获得的错误是NSXMLParserEmptyDocumentError。看来你没有得到你期望从服务器得到的响应;这不是解析器的问题。

您应该检查连接或响应是否发生错误，结果实际上是XML文档。

NSXMLParser在启动后立即停止
