使用特殊键在NavigationController中查找ViewController [英] Find ViewController in NavigationController with special key

问题描述

我有一个带有不同ViewController的NavigationController.有时我想将ViewController推送到NavigationController(已包含在内)中. 在这种情况下，我想从TopController移至现有控制器，并在top与现有控制器之间弹出所有其他ViewController.

I have a NavigationController with different ViewControllers. Sometimes I want to push a ViewController to NavigationController, which is already included. In this case I want to move to the existing from TopController, and pop all other ViewControllers between top and the existing one.

是否可以给ViewController一个特殊的ID(例如NSString)，以便稍后在"NavigationController.viewControllers"中找到他? 还是应该使用单独的Dictionary管理我的ViewController?

Is there a way to give a ViewController a special id (for example a NSString), to find him later in "NavigationController.viewControllers"? Or should I use a seperate Dictionary to manage my ViewControllers?

或者我没有更好的方法.

Or is there a better way, I dont consider.

最诚挚的问候

推荐答案

在appDelegate上，您可以存储所有ViewController以及要弹出呼叫的时间:

On your appDelegate, you can store all your ViewController and when you want to pop call :

[self.navigationController popToViewController:yourViewController animated:YES];

或者您可以尝试搜索

NSArray *viewControllers = self.navigationController.viewControllers 
for (UIVIewController *anVC in viewControllers) {
    if (anVC isKindOfClass:[yourController class] {
        [self.navigationController popToViewController:anVC animated:YES];
        break;
    }
}

希望它会对您有所帮助.

Hope it will help you.
