如何清除或重置 UINavigation 历史记录？
我有一个使用 UINavigation 的游戏设置屏幕，并且在用户选择颜色后尝试重置或清除 UINavigation。
下图可以最好地描述我的应用程序的当前流程：
Start application -> New game -> Pick character -> Pick Color -> Start game
在“选择颜色”之前，我使用 UINavigation，但是当选择颜色时，我想清除 UINavigation 历史记录。
这样做的原因是，一旦你开始游戏，你就无法返回，并且希望 UINavigation 保持干净状态，并且没有任何迹象表明你可以返回（这还包括返回到 主菜单屏幕）。
我现在的做法是这样的；
[self.navigationController popToRootViewControllerAnimated:YES];
GameDashboardVC *dashboard = [[GameDashboardVC alloc] initWithNibName:@"GameDashboardVC" bundle:nil];
dashboard.title = @"Dashboard";
dashboard.managedObjectContext = self.managedObjectContext;
[self.navigationController pushViewController:dashboard animated:YES];
[dashboard release];
问题是它弹出到 rootViewController 但它永远不会将仪表板推送到堆栈上。
我已经尝试过：
[self.parentViewController.navigationController pushViewController....]
我唯一没有尝试过的是将仪表板推送放入根视图控制器本身，但我很担心，因为我不确定它是否应该在那里。
因此，放置此类功能的正确位置在哪里，以及如何清除 UINavigation 的堆栈。
感谢您的时间/帮助。
I have a game setup screen which uses UINavigation and am trying to reset or clear the UINavigation once a person has selected a color.
My app's current process can be best described in the following diagram:
Start application -> New game -> Pick character -> Pick Color -> Start game
Up until "Pick Color" I use the UINavigation, however when a color is picked I want to clear the UINavigation history.
The reason for doing this is so that you can't go back once you've started the game and want the UINavigation to with a clean slate with no indication that you can go back (and this also includes going back to the main menu screen).
The way I am doing it right now is thusly;
[self.navigationController popToRootViewControllerAnimated:YES];
GameDashboardVC *dashboard = [[GameDashboardVC alloc] initWithNibName:@"GameDashboardVC" bundle:nil];
dashboard.title = @"Dashboard";
dashboard.managedObjectContext = self.managedObjectContext;
[self.navigationController pushViewController:dashboard animated:YES];
[dashboard release];
The problem is that it pops to the rootViewController but it never pushes the dashboard onto the stack.
I've tried:
[self.parentViewController.navigationController pushViewController....]
The only thing I haven't tried is putting my dashboard push inside the root view controller itself, but I am concerned because I am not sure if it should even be there.
Therefore, where is the correct place to put this kind of functionality, and how do I clear the UINavigation's stack.
Thank you for your time/help.

现在我满意地解决了这个问题。
我将以下代码放入 initWithNibName 方法中：
这隐藏了后退按钮，我不必弹出任何内容，但我认为出于内存原因，保留从堆栈中删除不需要的项目的想法可能会很有用。
但现在以上就可以了。
I solved the problem now to my satisfaction.
I put the following code inside my initWithNibName method:
This hid the back button and I didn't have to pop anything, but I think for memory reasons it might be useful to keep the idea of removing un-necessary items from the stack.
But for now the above will do.
如果要重置 UINavigation 历史记录，请重新初始化导航控制器。
如果您使用 AppDelegate 类中的 UINavigationController 。您可以重新初始化导航历史记录。
appDelegate.navigationController=[[UINavigationController alloc]init];
上面的代码将重置 navigationController 历史记录。
If you want reset the UINavigation History, reinitialise the navigation controller.
if you using UINavigationController from AppDelegate class. You can reinitialise the navigation history.
appDelegate.navigationController=[[UINavigationController alloc]init];
Above code will reset the navigationController history..
