从导航堆栈中删除viewcontrollers [英] Removing viewcontrollers from navigation stack

问题描述

我有一个导航堆栈，比如5个UIViewControllers。我想通过点击第5个viewcontroller中的按钮来删除堆栈中的第3个和第4个viewcontrollers。是否有可能做到这一点？如果是这样的话？

I have a navigation stack, with say 5 UIViewControllers. I want to remove the 3rd and 4th viewcontrollers in the stack on the click of a button in the 5th viewcontroller. Is it possible to do this? If so how?

推荐答案

使用此代码并享受：

NSMutableArray *navigationArray = [[NSMutableArray alloc] initWithArray: self.navigationController.viewControllers];

// [navigationArray removeAllObjects];    // This is just for remove all view controller from navigation stack.
[navigationArray removeObjectAtIndex: 2];  // You can pass your index here
self.navigationController.viewControllers = navigationArray;
[navigationArray release];

希望这会对你有帮助。
