So I am trying to create an iphone app and I am trying to set up the navigation controller. I got it to work from one view to another and then back.(code below) Is there a way to do it for multiple views? For instance, starting from the beginning pressing one button that changes to another view then pressing another button that goes to another different view. How would I implement the navigation controller to work without using storyboard and actually programming it? Any tips would be appreciated thanks.
This is in AppDelegate:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
LoginViewController *loginController = [[LoginViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:loginController];
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
This is in one of the button methods in one of the views:
[self.navigationController pushViewController:mainViewController animated:YES];
That is what the navigation controller do.
You can navigate to multiple views like this;
To navigate from main view to secondViewController
[self.navigationController pushViewController:secondViewController animated:YES];
The current navigation stack is mainViewcontroller -> secondViewController
From second View to third View
[self.navigationController pushViewController:thirdViewController animated:YES];
The current navigation stack is mainViewcontroller -> secondViewController - >thirdViewController
To go back to previous view you can call
[self popViewControllerAnimated:YES];
for 1 to 2 view
[self.navigationController pushViewController:secondViewController animated:YES];
from 2 to 3 view
[self.navigationController pushViewController:thirdViewController animated:YES];
back from 3 to 2 view
[self popViewControllerAnimated:YES];

I have a problem that my iOS app has several ViewControllers.
For example: ViewControllers named like A, B, C. A jumped to B with pushViewController, B jumped to C with presentViewController , C jumped to D with presentViewController and so on.
If the current ViewController is Z or some other ViewController, how can I jump back to A directly?
Try Below code. It will work for all cases :
for (UIViewController *controller in self.navigationController.viewControllers)
{
if ([controller isKindOfClass:[nameOfYourViewControllerYouWantToNavigate class]])
{
if(controller.isBeingPresented)
[controller.presentingViewController dismissViewControllerAnimated:YES completion:NULL];
else
[self.navigationController popToViewController:controller animated:YES];
break;
}
}
[[self navigationController] popToRootViewControllerAnimated:YES];
It will pop your viewcontroller to Root controller.
For the view controllers show by pushViewController, you can get rootViewController via [self.navigationController.viewControllers objectAtIndex:0]
Others shown by presentViewController, you can get parent view controller via self.presentingViewController
Whatever you want to go back to A ViewController from any other view controller, first you have to set that as RootViewController. If you use XIB you must set as root in app delegate didFinishLaunchWithOptions method. If you use storyboard you should set NavigationController in storyboard and set AViewController as ROOT using control+drag(mouse).
I work in a project which has lot of view controllers. It has pushViewController and PresentViewControllers also I set A asRootViewController. So I can return from any view controller to RootViewController.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
self.window = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen] bounds]];
AViewController *aVC = [[AViewController alloc]initWithNibName:#“AViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:aVC];
self.window.rootViewController = aVC;
[navController setNavigationBarHidden:YES];
self.window.backgroundColor = [UIColor clearColor];
[self.window makeKeyAndVisible];
return YES;
}
For going to AViewController from any other view controller
- (IBAction)actionGoBack:(id)sender
{
[self.navigationController popToRootViewControllerAnimated:YES];
}
I'm new to Objective-C and I want to add a UINavigationBar on my CatrgoryBIDViewController. I have proceed UIButton in InstructionBIDViewController.m file that should navigate to CatrgoryBIDViewController. Here is the function code:
- (IBAction)proceed:(id)sender {
viewControllercat =
[[CatrgoryBIDViewController alloc]
initWithNibName:#"CatrgoryBIDViewController"
bundle:nil];
UINavigationController *nav =
[[UINavigationController alloc]
initWithRootViewController:self.viewControllercat];
//[self.navigationController pushViewController:viewControllercat animated:YES];
[self.navigationController setNavigationBarHidden:NO animated:YES];
}
But it is not setting the UINavigationBar.
You should read the documentation here to understand the way a NavigationController is working. For your case:
If your current ViewController (where your proceed-method is implemented) has a NavigationController (is child of it), you can push another ViewController onto the stack of that NavigationController with
[self.navigationController pushViewController:viewControllercat animated:YES];
In this case you do not need to initialize another NavigationController, but in your CatrgoryBIDViewController in viewWillAppear you need to make the NavigationBar visible if it was not before already with
[self.navigationController setNavigationBarHidden:NO animated:YES];
If your current ViewController does not have a NavigationController, you can not push another ViewController on top of it and can not show the NavigationBar of it (although you can create your own NavigationBar and add it to the View of the ViewController, but without the usual Navigation-behaviour embedded).
If you open your ViewController programmatically (e. g. from the AppDelegate) you are correct to do so by your call:
viewControllercat = [[CatrgoryBIDViewController alloc] initWithNibName:#"CatrgoryBIDViewController" bundle:nil];
UINavigationController *nav=[[UINavigationController alloc] initWithRootViewController:self.viewControllercat];
My apologies - After having reread your question, I am going to tweak my answer some.
-(IBAction)proceed:(id)sender
{
viewControllercat = [[CatrgoryBIDViewController alloc] init];
UINavigationController * nc =
[[UINavigationController alloc] initWithRootViewController:vc];
// We now need to display your detail view but cannot push it.
// So display modally
[self presentViewController:nc animated:YES completion:Nil];
}
The above should result in your DetailViewController - CategoryBIDViewController being displayed on top of your InstructionBIDViewController and it should have a UINavigationController in it.
Hi Fellow iOS Developers, I am a newbie developing a project with 5 tab Views and on the first and second tabs I have slide out menus using Container views from example code by Michael Frederick on his GitHub page Project Link: https://github.com/mikefrederick/MFSideMenu. He is using a nib (.xib) files though I am using Storyboard to achieve the same and struck with defining the container and child views. can kindly some one advice how to modify the below code to accommodate in my storyboard.
the original code in the AppDelegate.m is
- (DemoViewController *)demoController {
return [[DemoViewController alloc] initWithNibName:#"DemoViewController" bundle:nil];
}
- (UINavigationController *)navigationController {
return [[UINavigationController alloc]
initWithRootViewController:[self demoController]];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITabBarController *tabBarController = [[UITabBarController alloc] init];
[tabBarController setViewControllers:[NSArray arrayWithObjects:[self navigationController],
[self navigationController], nil]];
SideMenuViewController *leftSideMenuController = [[SideMenuViewController alloc] init];
SideMenuViewController *rightSideMenuController = [[SideMenuViewController alloc] init];
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:tabBarController
leftMenuViewController:leftSideMenuController
rightMenuViewController:rightSideMenuController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
return YES;
}
#end
how to modify the code to accommodate the container parent view and child views ?
where should i instantiate the code for the parent and child of the 2nd tab view ? in AppDelegate or the View Controller ?
If any other Details are required leave a comment please. Any Help Will be greatly appreciated. thanks in Advance.
I don't know if you still need this, but i had the exactly same problem today, too. What you need to do is:
remove the both methods over your app Delegate
put this in your app Delegate:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"YOUR_STORYBOARD" bundle:[NSBundle mainBundle]];
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"THE_IDENTITY_OF_YOUR_SIDEMENU"];
UITabBarController *centerViewController = [storyboard instantiateViewControllerWithIdentifier:#"IDENTITY_OF_YOUR_TABBARCONTROLLER"];
[container setCenterViewController:centerViewController];
[container setLeftMenuViewController:leftSideMenuViewController]; //for the right Side, its the same way...
[container setPanMode:MFSideMenuPanModeNone]; //remove this line, if you need the pan mode
return YES;
In your Storyboard you have to put a ViewController as a subclass from "MFSideMenuContainerViewController". Mark this View as the "Initial View Controller" in the Attribute Inspector. Now use a Segue from your new Initial View Controller and let it "push" to your TabBarController. To avoid a Warning rename the Segue.
After you have done this, you can add a UIBarButtonItem to every View, you like to add the SideMenu. In the Action Method of this UIBarButtomItem you only need to do this:
[self.menuContainerViewController toggleLeftSideMenuCompletion:^{}];
finally make sure you have a UIViewController or a UITableViewController, that is your "SideMenu" and set the right Storyboard ID.
if you are still need help, comment this...
and sorry for my english :)
You can use https://github.com/ozcanakbulut/VoovilSideMenu. It's easy to embed in a tabBarController. It uses Storyboard and Arc.
In my delegate class I have this -
BluenibViewController *mvc = [[BluenibViewController alloc] init];
UINavigationController *unvc = [[UINavigationController alloc] init];
[unvc pushViewController:mvc animated:NO];
[mvc release];
[self.window addSubview:unvc.view];
[self.window makeKeyAndVisible];
return YES;
and in my BluenibViewController I have this method -
-(IBAction) BookingsViewController:(id)sender
{
bookingsViewController1 = [[BookingsViewController alloc]
initWithNibName:#"BookingsViewController"
bundle:nil];
UINavigationController *navController = self.navigationController;
[navController pushViewController:bookingsViewController1 animated:YES];
self.title = #"Bookings";
[self.window makeKeyAndVisible];
[self.view addSubview:bookingsViewController1.view];
[navController release];
[bookingsViewController1 release];
}
Ob click of this method I am able to go to the next view but there is no back button on the navigation bar.
Please point me to the silly mistake I am doing.
I see quite a few errors here. Lets see if I can't be of some service.
First, I see that you're overreleasing your navigation controller [navController release];
Second, you should only have to make the window key/visible once in your entire project. You set your navController as the rootViewController for your window, make it key/visible, and then you should never have to do anything with your window again. Don't think it's breaking anything, but you should remove all calls to make key/visible beyond the first.
In the end, pushing a new view controller should look like this:
[self.navigationController pushViewController:[[[BookingsViewController alloc] init] autorelease] animated:YES];
You shouldn't need anything else to get what you're looking for.
You should not add unvc.view as a subview of self.window. You should just assign unvc as self.window.rootViewController:
self.window.rootViewController = unvc;
and you should not add bookingsViewController1.view as a subview of self.view (in your BookingsViewController: method). The navigation controller will take care of getting bookingsViewController1.view onto the screen after you have pushed it.
self.navigationItem.hidesBackButton =YES;
Follow this code . Hope it helps ....
it comes a little bit late but in iOS 8 you can do:
[self.navigationController pushViewController:secondViewController animated:YES];
I'm building an app which's delegate has a UINavigationController (navigationController). The first view is a UITabViewController (tabView) which has a UINavigationController with a UIViewController with a UITableView which shows some contacts.
What I want to do is to push a new viewcontroller with the contact's info when tapping over a contact in the tableview (over the toppest navController)
I do the following in the appDelegate:
[self.window makeKeyAndVisible];
[self.window addSubview:[navigationController view]];
TabsView *tabsView = [[TabsView alloc] initWithNibName:nil bundle:nil];
[navigationController.view addSubview:[tabsView view]];
tabsView's first tab loads ContactsView.m which has a UINavigationController with all contacts and when someone clicks on one row, it is supposed to push the new view as this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[table deselectRowAtIndexPath:indexPath animated:YES];
ContactSecondView * varContactSecondView = [[ContactSecondView alloc] initWithNibName:nil bundle:nil];
varContactSecondView.title = [[contactsArray objectAtIndex:indexPath.row] name];
[self.navigationController pushViewController:varContactSecondView animated:YES];
[varContactMapView release];
}
But nothing happens when touching in a row.
So I have different files: Delegate with UINavigationController <- UITabViewController <- UIViewController with UINavigationController with UITableView; and I want to push a ViewController into the first navigationcontroller.
How is supposed to access to delegate's navigationController? Am I doing it right?
Edit: If this gives any clue, when I do self.navigationController.title = #"Contacts"; in ContactsView.m, it's not changing the title of the topbar.
Thanks!
Two things.
It is not recommended to embed a UITabBarController in a navigation controller. It is ok to embed a UINavigationController within a UITabBarController. I know it would be a "nice to have" to embed your UITabBarController in the UINavigationController, but you may want to rethink your design so that you follow the iOS design philosophy.
Instead of adding the subview to the window in your appDelegate, try adding which ever controller you are using to the window's rootViewController property i.e,
self.window.rootViewController=navigationController;
I may be wrong, but I think you don't use the correct way to set your view controller in your navigation controller.
You do :
[navigationController.view addSubview:[tabsView view]];
I would use :
[navigationController setViewControllers:[NSArray arrayWithObject:tabsView] animated:NO];
