emptyDataSetSource和emptyDataSetDelegate 在声明时对循环引用一点的疑问？ #49

Open bestannwn opened 2 years ago

在项目源码中在声明emptyDataSetSource和emptyDataSetDelegate的时候为啥不需要加 weak？项目中是： public var emptyDataSetSource: EmptyDataSetSource? public var emptyDataSetDelegate: EmptyDataSetDelegate?

为什么不设置为 public weak var emptyDataSetSource: EmptyDataSetSource? public weak var emptyDataSetDelegate: EmptyDataSetDelegate?

还望大佬讲解一下？谢谢～
