i created an app from the navigation-based template given by apple. Now i want to add a second navigation controller to my application including a new UITableView. Can anybody show my how to do this? Thanks!

推荐答案

我认为可以做到.在您的应用程序委托中，您通常会执行以下操作 [window addSubview:navController.view]. UIWindow只是一个UIView.因此，如果您在UIViewController中创建两个UIView ivars，它们将包含两个导航控制器，则您应该能够执行类似的操作:

I think this can be done. In your app delegate you normally do something like [window addSubview:navController.view]. UIWindow is just a UIView. So if you create two UIView ivars in the UIViewController that will contain the two nav controllers you should be able to do a similar thing:

@interface MyViewController : UIViewController
{
  UIView* upperView;
  UIView* lowerView;
}

等...

MyUpperRootViewController* myUpperRVC = [[MyUpperRootViewController alloc] init...
UINavigationController* myUpperNavController = [[UINavigationController alloc] initWithRootViewController:myUpperRVC];
[upperView addSubview:navController.view];
[myUpperRVC release];

以及lowerView上的类似内容.

在推入控制器的根视图或子序列视图中，以通常的方式访问它们，就像有一个导航控制器一样. [self.navigationController push...应该表现正常.

In the root view or subseqeunt views pushed onto the controllers access them in the usual way as if there was one nav controller. [self.navigationController push... should behave normally.

要使视图控制器动画化(或动画出)，只需将动画应用于视图-upperView或lowerView.您可能要先从可见显示的帧开始，然后将其更改为动画块内可见的帧.

For animating in (and out) the view controllers, just apply the animation to the views - upperView or lowerView. You might want to start with their frames off the visible display and then change them to something visible inside an animation block.
