Question

i created an iPad application, in which navigation is not working,
for example on click of cell of tableView, it should navigate to new view.

code snippet for the same:

appDelegate.m

-(void)applicationDidFinishLaunching:(UIApplication *)application {    

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

After this i am creating UIViewControllerSubclass, crollnext.

Inside this file i am performing some operation,and finally in my mainViewController

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    crollnext *crollController =[[crollnext alloc]initWithNibName:@"crollView" bundle:nil];

    [self.navigationController pushViewController:crollController animated:YES];
    [crollController changeProductText:[tableData objectAtIndex:indexPath.row]];
}
}

Have i made any mistake in code ?

here is a screenshot

Thanks In Advance

[window addSubview:navController.view];
[window addSubview:viewController.view];

Notice that you are adding your viewController.view on top of the window’s stack of views, after adding your navController.view. What you should do is something like this:

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

The navController, for itself its nothing. You need to fill it with something (in this case your viewController as the rootViewController.
