在UITableViewController中弹出多个级别 [英] Popping multiple levels in UITableViewController

问题描述

我希望能够从UITableViewController堆栈中弹出多个视图。例如，在Apple DrillDownSave示例中，当查看级别3以返回级别1或查看项目时，按下按钮时返回级别2.

I would like to be able to pop multiple views from a UITableViewController stack. For example in the Apple DrillDownSave example, when viewing Level 3 to go back to Level 1 or when viewing an Item to go back to Level 2 when a button is pushed.

我试过了：

[self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO];
[self.navigationController popViewControllerAnimated: NO];  

和

[self.navigationController popViewControllerAnimated: NO];  
[self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO];

但这些只留下一个popViewControllerAnimated：有没有一种简单的方法可以做到这一点？

but these leave me the same place as just a single popViewControllerAnimated:. Is there an easy way to do this?

推荐答案

你想要的是发送 popToViewController：animated： 到导航控制器。您可以使用导航控制器的 viewControllers 属性来确定要弹出的视图控制器。

What you want is to send popToViewController: animated: to the navigation controller. You can use the navigation controller's viewControllers property to figure out which view controller it is that you want to pop to.
