One, Introduction as the C,controller in the MVC design pattern has been the most important role in project development, it is a bridge between view and data, through its management, the data methodically displayed on our view layer. Uiviewcontroller in iOS is one of the most basic classes in the Uikit framework. From the first UI view to the complex complete project, it is inseparable from the uiviewcontroller as the basis. Based on Uiviewcontrolle

request;There is a successor that is used to forward requests that are not currently processed to the next node to form a chain. (successor refers to the next Concretehandler reference, which is equivalent to the next pointer in the list)Because of the above programming design, the object that requests and processes the request is completely independent, because the client does not even know who handled the request, so that the entire chain structure is very flexible, you can add new nodes at a
