objective-c - ios model 有一个属性也是model类型，初始化时，进入死循环，怎么破？

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;
  }

注释那个行使程序进入了死循环，这个要怎么改？

Answer 1

It is also very convenient to initialize and load attributes using the getter method. To call yourself in a method, there needs to be an end condition.
