iPhone SDK - 以编程方式添加UINavigationController [英] iPhone SDK - Add a UINavigationController Programmatically

问题描述

我有一个iPhone项目，其中目前没有 UINavigationController 。相反，我通过自己处理视图层次结构来交换视图。但是 - 你可能知道 - 这是不好的做法，所以我想弄清楚如何在我当前的应用程序中实现 UINavigationController 。我显然可以开始我的项目并使用Xcode模板，但我真的不想这样做。

I have an iPhone project which currently does not have a UINavigationController in it. Instead I swap views by handling the view hierarchy myself. However - as you're probably aware - this is bad practice, so I am trying to figure out how to implement a UINavigationController into my current app. I can obviously start my project over and use an Xcode template, but I really don't want to do this.

必须有办法做到这一点以编程方式。但我无法弄清楚需要在AppDelegate中使用哪些代码。有人对这个有经验么？我现在处于亏损状态。

There must be a way to do this programmatically. But I can't figure out what code needs to go in the AppDelegate. Does anyone have any experience with this? I am at a loss at the moment.

干杯，
Brett

推荐答案

Yeap。

- (void)applicationDidFinishLaunching:(UIApplication *)application 
{
   navController=[[UINavigationController alloc] init];
   MyViewController *firstController=[[MyViewController alloc] init];
   [navController pushViewController:firstController animated:NO];
   [window addSubview: navController.view];
} 
- (void) dealloc
{
   ...  
   [navController release];
   ...
}

这是一个很常见的问题，看看在这个....
