objective-c - ios model 有一個屬性也是model型，初始化時，進入死循環，怎麼破？

Question

• (instancetype)initFromDictionary:(NSDictionary *)dictionary
  {ShowLog
  self = [super init];
  if (self) {

     _cid        =       StringValue(dictionary, KID);
     _user       =       [[User alloc] initFromDictionary:DictionaryValue(dictionary, Kuser)];
     _images     =       ArrayValue(dictionary, Kimages);
     _content    =       StringValue(dictionary, Kcontent);
     
     //_beCommented=       [[Comment alloc] initFromDictionary:DictionaryValue(dictionary, KbeCommented)];
     _createTime =       DateValue(dictionary, KcreateTime);
     _ownerId    =       StringValue(dictionary, KownerId);

  }
  return self;
  }

註解那個行使程序進入了死循環，這個要怎麼改？

Answer 1

屬性用getter方法初始化載入也很方便，一個方法裡面又要呼叫自己，需要有一個結束條件。
