ios - Restkit v0.20动态映射到NSDictionary

Question

在Restkit v0.10中，可以使用来自https://stackoverflow.com/a/12057398/871459的以下代码来映射到NSDictionary

RKObjectMapping* mapping = [RKDynamicObjectMapping dynamicMapping];
mapping.objectMappingForDataBlock = ^(id data) {
    NSDictionary* object = [data objectForKey: @"object"];
    NSArray* keys = [object allKeys];

    RKObjectMapping* dataMapping = [RKObjectMapping objectMapping];
    //Use the keys to define mapping
    return dataMapping;
};

在v0.20中，这不再可行。如何在Restkit v0.20上实现相同功能？

Answer 1

在0.20中，他们使用RKDynamicMapping而不是RKDynamicObjectMapping。我还没有测试过，但是答案可能在这里:

RKDynamicMapping* dynamicMapping = [RKDynamicMapping new];    
[dynamicMapping setObjectMappingForRepresentationBlock:RKObjectMapping *^(id data) {
    NSDictionary* object = [data objectForKey: @"object"];
    NSArray* keys = [object allKeys];

    RKObjectMapping* dataMapping = [RKObjectMapping objectMapping];
    //Use the keys to define mapping
    return dataMapping;
}]; 

或看看 their tutorial for 0.20:
