如何从uinavigationcontroller堆栈中删除特定的视图控制器？ [英] How to remove a specific view controller from uinavigationcontroller stack?

问题描述

我有一个uinavigationcontroller。登录后我想从UInavigationcontroller堆栈中删除诸如RegisterViewController，LoginViewController等视图控制器..

I have a uinavigationcontroller. After logged in i want to remove viewcontrollers like RegisterViewController,LoginViewController etc from UInavigationcontroller stack..

我的意思是我必须从堆栈中删除特定的视图控制器？怎么可能。 ？

I mean i have to remove a particular view controller from stack ? How its possible. ?

我查了这篇文章

所以我们可以把它变成一个数组，比如

So we can take it into an array like

NSArray *allviewcontrollers= [(UINavigationController *)navigationController viewControllers];

但是如何进一步处理..这个问题很长时间都在追捕..请回答我..谢谢提前

But how to do further process.. This question is hunting me for long time..Please answer me ..Thanks in advance

推荐答案

NSMutableArray *allViewControllers = [NSMutableArray arrayWithArray: navigationController.viewControllers];
[allViewControllers removeObjectIdenticalTo: removedViewController];
navigationController.viewControllers = allViewControllers;
