如何在 Swift 中弹出特定的视图控制器 [英] How can I pop specific View Controller in Swift

问题描述

我使用下面的 Objective-C 代码来弹出一个特定的 ViewController.

I used the Objective-C code below to pop a specific ViewController.

for (UIViewController *controller in self.navigationController.viewControllers) {
    if ([controller isKindOfClass:[AnOldViewController class]]) { 
        //Do not forget to import AnOldViewController.h
        [self.navigationController popToViewController:controller
                                              animated:YES];
        break;
    }
}

我怎样才能在 Swift 中做到这一点?

推荐答案

试试下面的代码:

for controller in self.navigationController!.viewControllers as Array {
    if controller.isKind(of: ViewController.self) {
        self.navigationController!.popToViewController(controller, animated: true)
        break
    }
}
