@interface nextNavViewController : UINavigationController

I have "nextNavViewController.xib" which contains a table , some buttons and customized navigation bar. I want this interface to be loaded but it loads blank navbar with blank screen.

Is the thing i am doing possible? What i have to do to load the customized interface??

Answer 1

A couple of things:

1) Careful with the name of your classes. Make sure they follow the objective-c standards

2) You don't need to sub-class a UINavigationController . If you want to receive some of the capabilities of a UINavigationController , just:

contr = [[nextNavViewController alloc]initWithNibName:@"nextNavViewController"bundle:nil];

UINavigationController *myNavigation = [[UINavigationController alloc] initWithRootViewController:contr];

[self presentViewController:myNavigation animated:YES completion:nil];
