我用它工作了两天...我想获取远程 xml，然后将其解析/映射到核心数据。我已经阅读了一堆教程，所以此时我可以连接本地服务器（yyuupii！），获取 xml，但我在映射时遇到了问题。我明白了

-[RKObjectLoader canParseMIMEType:] 找不到 MIME 类型“application/xml”的解析器

-[RKObjectLoader isResponseMappable] 遇到意外响应，状态码：200（MIME 类型：application/xml -> URL：http:///list.xml -- http:/// -- http:/// -- http: ///) 2012-10-24 14:13:12.201 Sierpien[4650:907] Error Domain=org.restkit.RestKit.ErrorDomain Code=4 "操作无法完成。(org.restkit.RestKit.ErrorDomain错误 4.)"

你能给我一些建议吗，我将不胜感激。

我的 XML

<packs>
    <pack>
        <cover>cover.png</cover>
        <info>Jakis.adres.pl</info>
        <link>Opis</link>
        <name>wrzesień</name>
        <price>5.00</price>
    </pack>
    <pack>
        <cover>cover2.png</cover>
        <info>Jakis1.adres.pl</info>
        <link>Opis31</link>
        <name>wrzesień12</name>
        <price>15.00</price>
    </pack>
</packs>

我的实体

@interface Pack : NSManagedObject

@property (nonatomic, retain) NSString * name;
@property (nonatomic, retain) NSString * link;
@property (nonatomic, retain) NSString * price;
@property (nonatomic, retain) NSString * info;
@property (nonatomic, retain) NSString * cover;

@end

我的实现

- (id)initClient
{
    self = [super init];
    if (self) {
        RKObjectManager *client = [RKObjectManager objectManagerWithBaseURL:[RKURL URLWithString:@"http://10.1.1.5:8888/"]];
        NSLog(@"I am your RKObjectManager singleton : %@", [RKObjectManager sharedManager]);
        client.serializationMIMEType = RKMIMETypeXML;

        RKObjectMapping* listMapping = [RKObjectMapping mappingForClass:[Pack class]];
        [listMapping mapKeyPath:@"cover" toAttribute:@"cover"];
        [listMapping mapKeyPath:@"name" toAttribute:@"name"];
        [listMapping mapKeyPath:@"info" toAttribute:@"info"];
        [listMapping mapKeyPath:@"link" toAttribute:@"link"];
        [listMapping mapKeyPath:@"price" toAttribute:@"price"];

        [[RKObjectManager sharedManager].mappingProvider setMapping:listMapping forKeyPath:@"packs.pack"];
    }
    return self;
}

- (void)loadPacks {
    [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/list.xml" delegate:self];
}

好的，我扔掉 RKObjectManager，现在我连接 RKClient，获取 xml

[[RKClient sharedClient] get:@"/list.xml" delegate:self];

然后我通过 GDataXML 解析 Xml，用解析后的数据填充 Pack。有用。
