Ios RestKit映射上的关系错误

我真的不明白我为什么会出错：/ 有人能看看吗

2015-09-16 10:13:25.018偶像检查[26031:954937]我打赌这就是错误

具体来说，
toKeyPath:@“winners”
您的winners模型没有
winners
属性。
relationshipMappingFromKeyPath是WinnerList属性，而toKeyPath是json属性，不是吗？其目的是将WinnerMapping（许多Winner对象）的所有内容都设置为WinnerList对象。所以赢家不需要赢家属性你是对的。我注意到一个无法识别的选择器错误“[Winner winners]”，并假设是这样的。我猜你已经解决了这个问题，如果不是的话，我觉得赢家的地图错了。这可能导致了一个解析错误。尝试使用与上述winnerListMapping相同的字典。是的，我解决了这个问题。但这不是真正的问题；）我真的不明白为什么它不起作用，但我改变了我的方式，现在它起作用了。谢谢：）
