Ios CoreData&；RestKit崩溃：'；ALL或ANY运算符的左侧必须是NSArray或NSSet；

我正面临一个奇怪的CoreData相关崩溃

我正在使用RestKit2，它在mainMOC和persistentMOC之间具有父子关系。 导致崩溃（但几乎不可复制）的原因是将新实体存储到CoreData中（使用mainMOC），然后尝试检索与以前存储的实体有关系的对象（再次使用mainMOC）

堆栈跟踪不包含任何来自我的代码的指示。把这两种情况结合起来似乎有些可疑。 崩溃发生在iOS7和iOS8以及设备和模拟器上

有人有这方面的经验吗

似乎相关：您配置了哪些FRC以及它们是如何设置的？在两个单独的表视图中使用了两个FRC。两者都使用主队列上使用的MOC。每个FRC都有自己的请求。
