I want to have a common navigation bar to RecieptViewController and StockViewController and the bar should contain back button to go back to InventoryViewController.....
this code is written in InventoryViewController viewDidLoad:-
RecieptViewController *firstVC=[[RecieptViewController alloc]init];
UITabBarItem *itme1=[[UITabBarItem alloc]initWithTitle:#"First" image:nil tag:1];
itme1.title=#"Reciept";
[firstVC setTabBarItem:itme1];
StockViewController *secondView=[[StockViewController alloc]init];
UITabBarItem *item2=[[UITabBarItem alloc]initWithTitle:#"Second" image:nil tag:2];
item2.title=#"Stock";
[secondView setTabBarItem:item2];
[tapBarController setViewControllers:[NSArray arrayWithObjects:firstVC,secondView,nil]];
If you want to add navigation controllers to your UITabBarController then you must try the following:
UIViewController *viewController1, *viewController2;
UINavigationController *navigationController1, *navigationController2;
viewController1 = [[RecieptViewController alloc] initWithNibName:#"RecieptViewController" bundle:nil];
viewController2 = [[StockViewController alloc] initWithNibName:#"StockViewController" bundle:nil];
navigationController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
navigationController2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
[tapBarController setViewControllers:[NSArray navigationController1,navigationController2,nil]];

SecondViewController *testAppViewController2Obj =[[SecondViewController alloc]initWithNibName:#"TestAppViewController2" bundle:nil];
[self.navigationController pushViewController:testAppViewController2Obj animated:YES];
ContainerViewController *container = [[ContainerViewController alloc] init];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:container];
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 65)];
container.navigationItem.title = #"Frames";
self.window.rootViewController = nav;
i hope it works
In order to push a new view controller you should first create a view controller, VC1, link it with a navigation controller and then link the navigation controller to the rootViewController in the AppDelegate
#AppDelegate
FirstViewController *VC1 = [FirstViewController new];
UINavigationController *nVC = [UINavigationController alloc] initWithRootViewController:VC1];
self.window.rootViewController = nVC;
Then when VC1 gets pushed, you can create another view controller and push it like this:
#Now in VC1
SecondViewController *VC2 = [SecondViewController new];
[self.navigationController pushViewController:VC2 animated:YES];
I am relative new with the iOS app development. Currently I am developing a small app with a tab bar. The problem I am facing is that I would like to have different navigation items foreach tab. I tried a lot of things, but things aren't working. I am programming in the native iOS language.
In my app I've got a AppDelegate. In my AppDelegate there is a little piece of code for setting up my mainViewController:
- (void)setupOverlordViewController
{
MainViewController *rootVC = [[MainViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navVC = [[UINavigationController alloc] initWithRootViewController:rootVC];
self.window.rootViewController = navVC;
}
I am setting up my tabs in my MainViewController:
- (void)viewDidLoad
{
UIViewController *tabView1 = [[Tab1ViewController alloc] init];
UIViewController *tabView2 = [[Tab2ViewController alloc] init];
UIViewController *tabView3 = [[Tab3ViewController alloc] init];
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:tabView1];
[tabViewControllers addObject:tabView2];
[tabViewControllers addObject:tabView3];
[self setViewControllers:tabViewControllers];
tabView1.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"TabView1", nil)
image:[UIImage imageNamed:#"tabView1.png"]
tag:1];
tabView2.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"TabView2", nil)
image:[UIImage imageNamed:#"tabView2.png"]
tag:2];
tabView3.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"TabView3", nil)
image:[UIImage imageNamed:#"tabView3.png"]
tag:3];
}
Each View (tabView1, tabView2, tabView3) has there own layout, which is set in the ViewDidLoad method of the View. When I would like to add navigation buttons in the navigation bar by adding them in the ViewDidLoad method, but it seems impossible to add the buttons. The only way to add them is directly in my MainViewController, but then I can't set the navigation bar buttons different foreach tab.
The code for adding the buttons to my navigation bar is as follows:
UIBarButtonItem *btnNewRecord = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(btnNewRecord)];
NSArray *rightItems = [NSArray arrayWithObjects:btnNewRecord, nil];
[self.navigationItem setRightBarButtonItems:rightItems];
Could somebody explain me what I am doing wrong?
I have created a example for you by using xib files. I have created three View Controllers and added them to navigation controllers. Following the appdelegate code :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
FirstViewController *firstVC = [[FirstViewController alloc] initWithNibName:#"FirstView" bundle:nil];
UINavigationController *firstNavVC = [[UINavigationController alloc] initWithRootViewController: firstVC];
SecondViewController *secondVC = [[SecondViewController alloc] initWithNibName:#"SecondView" bundle:nil];
UINavigationController *secondNavVC = [[UINavigationController alloc] initWithRootViewController: secondVC];
ThirdViewController *thirdVC = [[ThirdViewController alloc] initWithNibName:#"ThirdView" bundle:nil];
UINavigationController *thirdNavVC = [[UINavigationController alloc] initWithRootViewController: thirdVC];
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:firstNavVC];
[tabViewControllers addObject:secondNavVC];
[tabViewControllers addObject:thirdNavVC];
firstNavVC.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"First", nil)
image:nil
tag:1];
secondNavVC.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"Second", nil)
image:nil
tag:2];
thirdNavVC.tabBarItem =
[[UITabBarItem alloc] initWithTitle:NSLocalizedString(#"Third", nil)
image:nil
tag:3];
UITabBarController *tabbarController = [[UITabBarController alloc] init];
tabbarController.viewControllers = tabViewControllers;
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.rootViewController = tabbarController;
[self.window makeKeyAndVisible];
return YES;
}
Following is the output :
You can download code example here
you need separate navigation controller for each tab bar view controller & then you can add UIBarButtonItem on each navigation controller.
When I push a view controller vc4 on navigtion controller I can change settings of vc4 navigation item (title, barbuttons etc) but when I push vc4 in a tabbarcontroller and I change navigation item settings the changes are not displayed.
The Code below is executed, when I tap on a cell in a tableviewcontroller. the tableviewcontroller was pushed on navigationcontroller which is the rootViewController set in MyAppDelegate.
UITabBarController* tabBarController = [[UITabBarController alloc] init];
MyViewController1* vc1 = [[MyViewController1 alloc] init];
MyViewController2* vc2 = [[MyViewController2 alloc] init];
MyViewController3* vc3 = [[MyViewController3 alloc] init];
MyNavRootViewController* vc4 = [[MyNavRootViewController alloc] init];
UINavigationController* navController = [[UINavigationController alloc]
initWithRootViewController:vc4];
NSArray* controllers = [NSArray arrayWithObjects:vc1, vc2, vc3, navController, nil];
tabBarController.viewControllers = controllers;
[[self navigationController] pushViewController:tabBarController animated:NO];
I have the following TabBarController with the uiTabBarItems
[Item1, Item2, Item3, Item4]
This struct works fine (Every ViewController is displayed correctly), my problem is:
When I change to another ViewController from Item1, Item2 ... the TabBarItems bottom are hidden/lose
[, , , ]
I'm using the following code to change of viewController from Item1 ViewController
NewViewController *controller = [[NewViewController alloc]init];
[self.tabBarController setViewControllers:[[NSArray alloc] initWithObjects:controller, nil]];
is correct change of viewcontroller with the code showed previously?
EDIT.-
Basically I want to navigate on ViewControllers of Item1 (UITabBar) without lost the UITabBarItems
If you want to set the active tab, you should't use setViewControllers: since that replaces all your tabs. You should use setSelectedIndex: on your UITabBarController instead.
Try this.
call this method , where to present UITabBar
In .h,
#property (strong, nonatomic) UINavigationController *navigation;
#property(nonatomic, strong) UITabBarController *tabbarcontroller;
In .m,
-(void)loadtabview
{
self.tabbarcontroller = [[UITabBarController alloc] init];
NSMutableArray *localControllersArray = [[NSMutableArray alloc] initWithCapacity:4];
self.firstViewController = [[FirstViewController alloc]initWithNibName:#"firstViewController" bundle:nil];
navigation = [[UINavigationController alloc] initWithRootViewController:self.firstViewController];
self.viewController.navigationItem.title=#"First";
[localControllersArray addObject:navigation];
self.secondViewController = [[secondViewController alloc] initWithNibName:#"secondViewController" bundle:nil];
navigation = [[UINavigationController alloc] initWithRootViewController:secondViewController];
self.secondViewController.navigationItem.title=#"second";
[localControllersArray addObject:navigation];
self.ThirdViewController = [[Third ViewController alloc]initWithNibName:#"Third ViewController" bundle:nil];
navigation = [[UINavigationController alloc] initWithRootViewController:ThirdViewController];
self.secondViewController.navigationItem.title=#"Third";
[localControllersArray addObject:navigation];
tabbarcontroller.viewControllers = localControllersArray;
self.tabbarcontroller.delegate = self;
[self.tabbarcontroller setSelectedIndex:0];
[self.window addSubview:tabbarcontroller.view];
}
I'm trying to add a UINavigationController to my existing view controller by adding this in ViewDidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
navController = [[UINavigationController alloc]init];
[self.view addSubview:navController.view];
}
But by doing it this way, it completely blocks my view. It puts a UINavigationBar on the top but the rest of the view doesn't respond to input.
This is how I am presenting the view. The SecondViewController is the one I want to have a NavController:
UITabBarController *tabController = [[UITabBarController alloc] init];
FirstViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"CardsViewController" bundle:nil];
UITabBarItem *tab1 = [[UITabBarItem alloc] initWithTitle:#"First"
image:[UIImage imageNamed:#"img1.png"] tag:1];
[viewController1 setTabBarItem:tab1];
SecondViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"ShoppingViewController" bundle:nil];
UINavigationController *SecondViewNavCont = [[UINavigationController alloc]initWithRootViewController:viewController2];
UITabBarItem *tab2 = [[UITabBarItem alloc] initWithTitle:#"Second"
image:[UIImage imageNamed:#"img2.png"] tag:2];
[SecondViewNavCont setTabBarItem:tab2];
UIViewController *viewController3 = [[UIViewController alloc] init];
UITabBarItem *tab3 = [[UITabBarItem alloc] initWithTitle:#"Third"
image:[UIImage imageNamed:#"img3.png"] tag:3];
[viewController3 setTabBarItem:tab3];
tabController.viewControllers = [NSArray arrayWithObjects:viewController1,
viewController2,
viewController3,
nil];
[self.view addSubview:tabController.view];
You cannot add it to the current view controller
What you need to do is instead of presenting the ViewController is to add this viewcontroller to the navigationview controller and present that
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:YourPresentedViewController];
//then present the navController
[self presentModalViewController:navController animated:YES];
Now when you present it do the following
NSArray arrayWithObjects:viewController1,
SecondViewNavCont,
viewController3,
nil];
You can try this code for load uiviewcontroller to uinavigationcontroller:
yourviewController *viewcontroller=[[yourviewController alloc] initWithNibName:#"yourviewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewcontroller];
[self presentModalViewController:navController animated:YES];
(or) you want to load uinavigationcontroller in application startup try below code in your application delegate class:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewcontroller.view];
[self.window addSubview:navController.view];
[self.window makeKeyAndVisible];
return YES;
}
Welcome!
You need to set the RootViewController for the navController object. Then further you can push UIViewcontroller objects using pushViewController method.
You need to add a view for that Navigation Controller. The added Navigation Controller has no view so it was overlaying on the UIViewController
You need to add
[[UINavigationController alloc] initWithNibName:#"ViewControllerName" bundle:nil];
