What is the difference between the Delegate.h and Delegate.m, and ViewController.h and ViewController.m files and their usage
推荐答案
委托是对象操作的附带事件，而控制器是必需的。它们也在物体的不同侧面;控制器控制所讨论的视图;
A delegate is incidental to the operation of the object, whereas a controller is required. They are also on different "sides" of the object; the controller controls the view in question; and the object delegates functionality to its delegate, if present, putting the controller above the object and the delegate beside it.
此外， .h <>
Also, .h files contain declarations; .m files contain code, if that was what you were asking.
