In my code i declare an @property for my Main class in my sub class to set values there
在我的代码中，我为我的子类声明一个@property来设置那里的值
@property(nonatomic,retain) MainViewController *father;
but i noticed that retain make the dealloc method not called in my main class, but when i change it to:
但是我注意到retain make dealloc方法在我的主类中没有调用，但是当我将它改为:
@property(strong, nonatomic) BabyViewController *father;
the dealloc method returned to be called.
返回dealloc方法以进行调用。
i did this without knowing if that effect my code performance or not.
我这样做时并不知道这是否会影响我的代码性能。
i used this property to do this in my main class:
我在主课程中使用了这个属性:
subClass* controller = [[subClass alloc] initWithPageNumber:page];
controller.father=self;
[controller.view removeFromSuperview];
is this the best i can do ??
这是我能做的最好的吗?

Better you can use assign property for the declaration of viewControllers and delegates.It will assign the data and won't dealloc the variable. So use like this,
更好的方法是为viewControllers和delegate的声明使用assign属性。它将分配数据，而不会释放变量。所以用这样的,
@property(nonatomic,assign) MainViewController *father;
