Implement navigation controller's in a view controller

Question

I have a view controller and I want to implement a navigation controller inside it, but when I implemented it through Interface Builder or programmatically it doesn't work.

Most of it I implemented through Interface Builder, but here is the code I implemented in the AppDelegate, and which I am trying to implement in my view controller.

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController];
[window addSubview:navController.view];

I know I can't implement "window" in a view controller so I tried this in my view controller:

[self.view addSubview:navController];

But it still doesn't work.

you need to do it like this [self.window addSubview:navController.view] and before initWithRootViewController you need to alloc your viewController object — stack2012

In the app delegate's applicationDidFinishLaunching you have to add this code.

viewController=[[myViewController alloc]init];
navigationController=[[UINavigationController alloc]initWithRootViewController:viewController];
[self.window addSubview:navigationController.view];

where viewController is the object of the myViewController class to which u need to add the navigation controller. It s declared in the header file of appDelegate.Similarly the navigationController is also declared in tat. Hope this helps.

New code:

AppSettings *settings = [[AppSettings alloc] init];
UINavigationController *navCont = [[UINavigationController alloc] initWithRootViewController:settings];
navCont.navigationBar.barStyle = UIBarStyleBlackTranslucent;
[self.navigationController presentModalViewController:navCont animated:YES];
[settings release];
[navCont release];

I have tried implementing this in my appDelegate under applicationDidFinishLaunching but I want to implement it through my own viewController.

I have my original view, and from that I launch the NewAlarm view but I don't do that using the navigation controller. I use presentModalViewController instead.

Try this in your -applicationDidFinishLaunching:

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
[self.window setRootViewController:navigationController];
[self.window makeKeyAndVisible];
