iOS - dismissViewControllerAnimated 与 popViewControllerAnimated 的区别

-dismissViewControllerAnimated:completion:

此方法用于dismiss 那些由 UIViewController 的-presentViewController:animated:completion: 方法 呈现出来的UIViewController

(这种情况，UIViewController是作为一个modal controller显示)

 

 

-popViewControllerAnimated:

此方法用于pop 那些由 UINavigationController 的-pushViewController:animated 方法 显示出来的UIViewController

(这种情况, 这个UIViewController是被push到UINavigationController的navigation stack栈中)
