为什么RestKit会产生深度递归的属性映射？

Question

我正在尝试将中等复杂的JSON映射到嵌套的对象结构中。 Shops对象是递归的，但ErrorStatus对象不是。但是，在reationshipMappingFromKeyPath：@“ErrorStatus”之后的调试断点显示了entityMapping - ＆gt; ErrorStatus通过_mutablePropertyMappings进行深度递归。不幸的是调试似乎不支持复制，否则我会在这里显示。任何提示都会受到高度赞赏。

    @implementation LLSResponse

    + (RKObjectMapping *)jsonMapping

        RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace);    //??? debugging

        NSLog(@"===== LLSResponse.jsonMapping/RestKitMapping");
