ResKit iOS-为同一元素注册多个类

Question

Hi-stackoverflow社区，我正在使用RKObjectManager进行iOS RESTful请求，以将响应映射到本地对象。

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"List"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]];

我想知道的是，是否有任何解决方案可以在不同的请求中为同一元素注册多个类？

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

您只需要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];
