Adding UINavigationController to existing UIViewController
提问by marko
How do I add an existing UIViewController (which is presented using presentModalViewController) to a UINavigationController?
如何将现有的 UIViewController（使用 presentModalViewController 呈现）添加到 UINavigationController？
When user tap on button, a new copy of my detail view need to be pushed. (In other words, pushViewController displaying pushViewController, modally, in a UINavigationController).
当用户点击按钮时，需要推送我的详细信息视图的新副本。（换句话说，pushViewController 在 UINavigationController 中模态地显示 pushViewController）。
Easiest way to enable this functionality?
启用此功能的最简单方法是什么？

how do you create your modal viewcontroller? Just wrap the controller into a UINavigationController
你如何创建你的模态视图控制器？只需将控制器包装成 UINavigationController
Let's assume your modal code is like this:
让我们假设你的模态代码是这样的：
MyExampleViewController *vc = [[[MyExampleViewController alloc] initWithNibName:@"MyExample" bundle:nil] autorelease];
[self presentModalViewController:vc animated:YES];
Then change it into something like this:
然后把它改成这样：
MyExampleViewController *vc = [[[MyExampleViewController alloc] initWithNibName:@"MyExample" bundle:nil] autorelease];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:vc] autorelease];
[self presentModalViewController:navController animated:YES];

I think you need to add a navigation controller in your delegate, after that you can push the view. So that you can push the view from anywhere in your application.
我认为您需要在您的委托中添加一个导航控制器，然后您可以推送视图。这样您就可以从应用程序的任何位置推送视图。
on AppDelegate.h
在 AppDelegate.h 上
UINavigationController *navig;
on AppDelegate.M
在 AppDelegate.M 上
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
navig = [[UINavigationController alloc] initwithRootViewController:viewController.view];
//[navig pushViewController:viewController animated:YES];
[self.window addSubview:navig.view];
[self.window makeKeyAndVisible];
return YES;
}
