[self.navigationController pushViewController:ngView animated:YES]; not working

Question

If i use

 NGViewController *ngView = [[NGViewController alloc]initWithNibName:Nil bundle:Nil];
[self presentViewController:ngView animated:NO completion:nil];

above code the controller will go to NGViewController page.

But if I use this navigation controller

NGViewController *ngView = [[NGViewController alloc]initWithNibName:Nil bundle:Nil];
[self.navigationController pushViewController:ngView animated:YES];

the Controller will be in same page.

Can any one tell that what's the problem.

Are you using a `UINavigationController`? If not, then `self.navigationController` will be `nil`. — borrrden, May 23 '13 at 09:51
yes i have not used UINavigationController so its not coming.... thanx 2 all — Nithinbemitk, May 23 '13 at 10:04
have you made your application `UINavigation` Based, if not then convert it to Navigation based app, then it will work — Dipen Panchasara, May 23 '13 at 18:24
make sure you are pushing the View Controller in navigation stack. otherwise self.navigationController will return nil; — msmq, Mar 25 '14 at 13:13

You should use this code

NGViewController *ngView = [[NGViewController alloc]initWithNibName:Nil bundle:Nil];
[self presentViewController:ngView animated:NO completion:nil];

after writting this line when then you you want go on different page with push view controller

UINavigationController *navigationController = [[UINavigationController       alloc]initWithRootViewController:ngView];

[self.navigationController pushViewController:navigationController animated:YES];

I hope you will solve this issue by this code Good luck

Your self.navigationController is probably nil - check it out through debugging. Your self view controller is not within a UINavigationController.

I hope you are ending the animations later...(P.S. this way of animating is really old [pre iOS 4]) – borrrden May 23 '13 at 10:18

Self Controller should have navigation controller (in Storyboard) in order to navigate.

[self.navigationController pushViewController:nextController animated:YES];

UINavigationController is a controller of controllers and it is designed to allow you to push and pop controllers and manage a hierarchy of your view's. And your navigationController property tells you whether your NGViewController is currently in a UINavigationController's hierarchy; if not (as in this case), the navigationController property returns nil.

You have to create your own navigation controller and then try to push the view controllers and thus build up a view hierarchy. I normally would suggest this:

 UINavigationController *navigationController = [[UINavigationController       alloc]initWithRootViewController:firstviewController];
[self.window setRootViewController:navigationController];
navigationController.delegate = self;
navigationController.navigationBarHidden = YES;

you need to declare this in your first controller

NGViewController *ngView = [[NGViewController alloc]init];
[self.navigationController pushViewController:ngView animated:YES];
