iphone - ResKit iOS - 为同一个元素注册多个类

Question

嗨 stackoverflow 社区，我正在使用 RKObjectManager 发出 iOS RESTful 请求以将响应映射到本地对象。

我对 Restkit 的问题是在不同的请求中为同一个 Element 注册多个类。在这个请求中，我嵌套了具有相同元素名称“列表”的对象。

以下是部分代码：

// Get array of RKObjects1 - First request of the queue
RKObjectManager * objectManager = [RKObjectManager sharedManager];
[objectManager registerClass:[RKTObject1 class] forElementNamed:@"List"];

RKObjectLoader * loader = [objectManager objectLoaderWithResourcePath:@"objects1" delegate:self];
[loader setObjectClass:[RKTList class]];



// Get array of RKObjects2 - Second request of the queue
RKObjectManager * objectManager = [RKObjectManager sharedManager];
[objectManager registerClass:[RKObjects2 class] forElementNamed:@"List"];

RKObjectLoader * loader = [objectManager objectLoaderWithResourcePath:@"objects2" delegate:self];
[loader setObjectClass:[RKTList class]];

我想知道，是否有任何解决方案可以在不同请求中为同一元素注册多个类？

好吧，为了解决我的问题，我更新了 restkit 并使用新的 Object Mapping 2.0 可以为相同的元素键注册多个类。

您只需为每个请求创建不同的 RKObjectMapping 对象，并在 RKObjectLoader 中对每个对象进行 setObjectMapping。

例如：

RKObjectMappingProvider * mappingProvider = [RKObjectManager sharedManager].mappingProvider; 

// Create 2 RKObjectMapping for each request
RKObjectMapping * object1Mapping = [RKObjectMapping mappingForClass:[RKTList class]];
[object1Mapping mapKeyPath:@"Id" toAttribute:@"idObject"];
[object1Mapping mapKeyPath:@"Name" toAttribute:@"name"];
[mappingProvider setMapping:object1Mapping forKeyPath:@"Objects1List"];


RKObjectMapping * object2Mapping = [RKObjectMapping mappingForClass:[RKTList class]];
[object2Mapping mapKeyPath:@"Id" toAttribute:@"idObject"];
[object2Mapping mapKeyPath:@"Name" toAttribute:@"name"];
[mappingProvider setMapping:object2Mapping forKeyPath:@"Objects2List"];

//Make the 2 request with explicit object mapping
RKObjectManager * objectManager = [RKObjectManager sharedManager];
RKObjectLoader * loaderFirstRequest = [objectManager objectLoaderWithResourcePath:@"objects1" delegate:self];
[loaderFirstRequest setObjectMapping:object1Mapping];

RKObjectLoader * loaderSecondRequest = [objectManager objectLoaderWithResourcePath:@"objects2" delegate:self];
[loaderSecondRequest setObjectMapping:object2Mapping];
