在视图控制器子类上添加导航控制器

Question

How do you add a navigation controller on a newly created view controller? i've search everywhere but all the tutorials are from creating a navigation controller project.

Anyone can lead mo to a tutorial that creates a navigation controller using a view controller subclass?

What i'm doing so far:

I created a UIViewController Project, and i have something like this to go to another view controller, with a navigation controller.

NavController *view=[[NavController alloc] initWithNibName:nil bundle:nil];
view.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:view animated:YES];
[view release];

Added a new view controller subclass.

Add > New File > UIViewController subclass with nib

on NavController.h

#import <UIKit/UIKit.h>


@interface NavController : UIViewController {

    IBOutlet UIWindow *window;
    IBOutlet UINavigationController *navCon;

}

@property (nonatomic, retain) UIWindow *window;
@property (nonatomic, retain) UINavigationController *navCon;

@end

on NavController.m

#import "NavController.h"


@implementation NavController

@synthesize window,navCon;


- (void)viewDidUnload {
    [super viewDidUnload];

}

- (void)dealloc {
    [window release];
    [navCon release];
    [super dealloc];
}


@end

i already dragged a Navigation Conrtoller and a Window on my IB, and connected window to window and the Navigation Controller to navcon outlets, but whats next?

如果您正在使用故事板，请选择您的视图控制器，然后在顶部菜单中选择“编辑器”/“嵌入”/“导航控制器”。

Normally, you have to create an Navigationcontroller object inside your Appdelegate.h (like the existing window object). After that you import the h.File of a ViewController into the Appdelegate.m and init it like in the following example the menuviewcontroller. stackoverflow

To call another view use following lines of code, so the navigationcontroller will handle everything for you.

#import Viewcontroller

ViewControllerName controllerVarName = [ViewControllerName alloc] init];

[self.navigationcontroller pushViewController:_ViewControllerName animated:YES];

Inside your specific ViewController use this line to set the title the Navigationcontroller will use:

self.title = @"titleName";
