change RootviewController to Navigation controller
Solution 1
Whenever u want to set:
DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:detailViewController];
self.window.rootViewController =nil;
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
EDIT : Directly use AppDelegate
instance
to set rootViewController
for UIWindow
as i have shown above.
Solution 2
Instead of:
[self.window addSubview:navigationController.view];
make navigationController
the rootViewController
of window
:
self.window.rootViewController = navigationController;
Also, is detailViewController
of type UINavigationController
? You cannot set UINavigationController
as root to another UINavigationController
object.
Solution 3
Just add this line,
RootViewController *defaultViewController=[[RootViewController alloc]initWithNibName:@"NAME_OF_XIB" bundle:nil];
before UINavigationController's initialization,
RootViewController *defaultViewController=[[RootViewController alloc]initWithNibName:@"NAME_OF_XIB" bundle:nil];
UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:detailViewController];
[self.window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
