I have structure of project as shown below.
On the left side I have MainViewController. There I have two buttons as English and Arabic. What I want to do is when I click English, I want to go English tab bar controller (HomeViewController).
Hence what I wrote is
- (IBAction)langEnglish:(id)sender {
HomeViewController *secondView = [self.storyboard instantiateViewControllerWithIdentifier:#"enghome"];
[self.navigationController pushViewController:secondView animated:YES];
}
This is working perfectly, but I don't see tab bar.
Tab bar is missing from this.
Any idea what is going wrong?
Basically what I have is view controller as main controller and upon clicking button on this controller, tab view controller should get open...
Go to your main storyboard and select your main view controller. On top select Editor->Embed in->navigation bar.
EDIT: If this does not work push to your tab bar and use this code:
self.tabBarController.selectedIndex = 1;
What I did is as below
- (IBAction)langEnglish:(id)sender {
EngTabViewController *secondView = [self.storyboard instantiateViewControllerWithIdentifier:#"engtab"];
[self.navigationController pushViewController:secondView animated:YES];
}
EngTabViewController is the UITabBarController and I assigned id to tab bar controller... this works like charm...
Means instead of viewcontorller, I used tabbarcontroller...
You shouldn't push a UITabBarController on a UINavigationController. Set it as the window's root view controller instead and the tab bar should be displayed as expected.

There is problem in view hierarchy. Here is flow of my app.
When app starts View Controller "A" is Visible. After that storyboard "B" is loaded through "StoryBoard Reference (Push)" ,Where another navigation controller is present and Home screen is loaded. On Click of Menu button in Home screen Side panel is visible.
Now When i click on side panel menu items view Controller "B" is pushed. This View Controller is Pushed Under Home screen and is not Vsible.
Help View contoller is visible under Home controller. I want Help View Controller should come on top of Home controller.
I dont understand what issue is coming..
Any Help will be appreciated..
If you are pushing view controller from side panel shows in image, will never push because it is not in navigation controller.
the answer depends on how you showing your side menu but from assumptions
what you need to do is to set root view controller or keep reference of navigation controller and push from there
If you are presenting side menu then it is not on navigation controller so you should first dismiss this side menu and on the completion of it you should push new view controller (says B or Help). I am writing my code snippet that i am using in my project for demonstration,
- (IBAction)settingClick:(id)sender {
SettingViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:#"settingsScreen"];
[self dismissViewControllerAnimated:NO completion:^{
[self.vc.navigationController.navigationController pushViewController:svc animated:YES];
}];
}
Above method push setting view controller on current navigation controller after dismissing side menu
Now important thing is self.vc this is the object of previous viewcontroller (Home controller in your case i think) on which side menu was presented.
So my SideMenuViewController has a property like,
#property (nonatomic,strong) UIViewController *vc;
which i am setting with self from previous view controller (in your case from Home view controller) something like,
SideMenuViewController *smvc = [self.storyboard instantiateViewControllerWithIdentifier:#"sideMenu"];
smvc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[self presentViewController:smvc animated:NO completion:^{
smvc.vc = self;
}];
And i have used [self.vc.navigationController.navigationController pushViewController:svc animated:YES]; i.e. two navigation controller to push because i have two navigation controller in my view hierarchy to push this new view controller.
You can manage that as per your setup that how many navigation controller you have !!
Hope this will help :)
After digging a lot, I found solution for this.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Home" bundle: nil];
RootController *someViewController = [storyboard instantiateViewControllerWithIdentifier:#"RootController"];
[self.navigationController pushViewController:someViewController animated:YES];
I have set another navigation controller as root ViewController of the window and it worked for me.
Thanks.
I have a tab bar controller with a button like so:
- (void) addButtonPressed:(UIButton *) sender
{
[sender setBackgroundColor:[UIColor regularColor]];
PostViewController *post = [[PostViewController alloc] init];
[self.navigationController pushViewController:post animated:YES];
}
This code runs but the PostViewController is never shown and the tab bar controller remains.
How do I get to push to a new controller?
The NavigationController was created and StartViewController was add as rootController.
Then in StartViewController I have:
TabBarController *tab = [[TabBarController alloc] init];
// Presentation
[self presentViewController:tab animated:NO completion:nil];
in tab bar you need to create separate Navigation Controllers.
Suppose there are 3 tabs A, B and C. All the three tabs have functionality of navigation from one view to another. than you need to create three separate Navigation controllers eact pointing to Tab A, B and C. In this way you can navigate to any class within the specific Tab.
Check out this link for more details.
Hope this will help you. Happy coding :)
You may need to embed your tab bar controller within a navigation controller, In your storyboard click on your tabbarController so that it is highlighted with all the blue lines and then go to Editor in Xcode choose embed IN> UINavigationController ..If you want to do it programatically then in your AppDelegate where you setup your Window just Use This::
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:tabBarController];
navigationController.toolbarHidden=YES;
navigationController.navigationBarHidden=YES;
self.window.rootViewController =navigationController;
if you are using .xib then you have to use NSBundle to load nib
if you are using storyboard then you need to use prepareForSegue to pass on data or just display it out
I'm new to xcode ios 7.
I've struggling a lot with navigation controls building app for iPhone ios7.
I don't want to use storyboard. I prefer to do it programmatically.
What i am trying to do.
I know how to create NavigationBar & Navigation Toolbar via AppDelegate.m
But if it's possible i don't want to do it, because let's assume i want in FirstViewController to show just simple button "Go to Second View Controller" (No Navigation Bar or Toolbar here).
And now in SecondViewController i want to create Navigation Toolbar (bottom) with 4 different tabs linking to ViewControllers!
But the trick is, i want to maintain different Navigation Bar (top) for every ViewController (as you can see in this screenshot).
Here is my Xcode Project File
And here is screenshot form Fancy app showing what i am trying to achieve.
Thanks a lot in advance!
Just to give you an idea, When you tap the button on your first view controller, you can create a UINavigationController and set your second view controller as its root view controller. This way, your first view controller remains no nav bar view and the second view controller holds a Navigation controller. Try something like below:
-(IBAction)goToSecondVC:(id)sender // An action for the button in your first VC
{
SecondViewController *secondVC = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil]; //Init with second view controller
UINavigationController *secondNavVC = [[UINavigationController alloc] initWithRootViewController:secondVC]; // create a navigation controller and set the root as your second view controller
[self presentViewController:secondNavVC animated:YES completion:nil]; // and then present it with anim or no anim..
}
I have a tab bar controller with 4 tabs and each tab is their own UINavigationController, which is how you're supposed to nest tab bar and navigation controller's together. The initial tab is a TableViewController and works/appears the way that it should. From the tableVC I can push standard view controller's onto the navigation controller with:
[self.navigationController pushViewController:VC animated:YES];
and it works properly.
If I attempt to push another TableViewController onto the navigation with the same method it works the same way, but the initial tab bar does not get pushed off screen like it should, it just stays in place.
Why would the tab bar stay on screen even though I am pushing a new VC onto the navigation?
I have tested with multiple instances of different TableVC's and it only happens with a table view controller.
Here is the code I'm using:
- (void)pushTableVC
{
TestTableVC *tableVC = [[TestTableVC alloc] init];
[self.navigationController pushViewController:tableVC animated:YES];
}
This will push the new table view onto the stack, but the tab bar from the parent VC stays in place and does not get pushed off screen like it should.
You should call the method setHidesBottomBarWhenPushed: on the view controller you are pushing to correctly hide the tab bar.
UIViewController *viewController = [[UIViewController alloc] init];
[viewController setHidesBottomBarWhenPushed:YES];
[[self navigationController] pushViewController:viewController animated:YES];
When you use a UITabBarController, the tab bar always stays on screen, even as you push additional view controllers onto an embedded UINavigationController. You will see this in any app that has a UITabBarController implemented, unless they implement custom behavior to change this.
The UINavigationController contains everything above the UITabBar, but does not contain the UITabBar itself, so it would not be able to push it offscreen.
I have an application with several view controllers controlled from a tab bar controller. From one of these view controllers I want to (on clicking a button) segue to another view controller and retain the tab bar at the bottom of the segued to view.
I've used
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([segue.identifier isEqualToString:#"newView"]){
UIViewController *controller =segue.destinationViewController;
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
}
}
This works fine except the tab bar is missing from the segued to view (a placeholder shows for it in the storyboard, but it doesn't show up when the app is run)
I've also tried replacing
[self presentModalViewController:controller animated:YES];
with
[self presentViewController:controller animated:YES completion:nil];
but that doesn't work either.
A bit of debugging shows that for the segued-to view controller, the tabBarController property is set to nil.
Is there anyway to retain the tab bar in the segued-to view controller?
From your explanation, I don't think you want a modal controller. Modal is used to overlay, rendering your tab bar useless. From your storyboard, select your segue and select push, not modal.
Push vs Modal (Note the tab bar):
