  1. 这个功能已经在开发中了,下个版本就会支持;
  2. JSONDeserializer<T: HandyJSON>.deserializeFrom(json: <String>) 方法,做的第一件事情便是:根据T类型来生成一个初始实例,这个过程便是调用了 let instance = T.init()。Swift中,class类型默认实现了空的init()构造函数,但一旦你为它指定了别的构造函数,这个空的就会被覆盖。所以协议中就要求必须显式实现一个空的,以便 let instance = T.init() 能够成功执行。

哦,原来是这样,那我如果在父model中实现了init方法,子model中就没必要再写一遍了吧

还是需要的,因为要拿到子model的实例,仍然需要子model指定一个构造函数。
