快速获取 UIViewController 的类名 [英] Get class name of UIViewController in swift

问题描述

如何快速获取UIViewController类的类名

在 Objective C 中，我们可以这样做:

In Objective C, we can do something like this :

self.appDelegate = (shAppDelegate *)[[UIApplication sharedApplication] delegate];
    UIViewController *last_screen = self.appDelegate.popScreens.lastObject ;

    if(last_screen.class != self.navigationController.visibleViewController.class){

    //.......

}

但很快我就这样尝试了

let appDelegate = UIApplication.sharedApplication().delegate as AppDelegate
    let last_screen = appDelegate.popScreens?.lastObject as UIViewController

不能这样做.

if last_screen.class != self.navigationController.visibleViewController.class{

//....

}

没有UIViewController的类方法，即最后一屏

no class method of UIViewController i.e last screen
