Pushing UITabBarController into UInavigationController - ios

I have a UINavigationController as the root view controller of an app.
At some point I need to push a UITabController with specific tabs.
Up to this point it all works.
However in the tab view controllers I can't access the UINavigationController navBar (to change title, tint, etc).
Here is how I push it:
SCTabController *TabController = [[SCTabController alloc] init];
[self.navigationController pushViewController:TabController animated:YES];
SCTabController is a subclass of UITabController with the following viewDidLoadMethod:
- (void)viewDidLoad {
[super viewDidLoad];
UIViewController *view1 = [[UIViewController alloc] init];
UIViewController *view2 = [[UIViewController alloc] init];
UIViewController *view3 = [[UIViewController alloc] init];
UIViewController *view4 = [[UIViewController alloc] init];
NSMutableArray *tabViewControllers = [[NSMutableArray alloc] init];
[tabViewControllers addObject:view1];
[tabViewControllers addObject:view2];
[tabViewControllers addObject:view3];
[tabViewControllers addObject:view4];
[self setViewControllers:tabViewControllers];
//can't set this until after its added to the tab bar
bankHomeViewController.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"Title1"
image:nil
tag:1];
view2.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"Title2"
image:nil
tag:2];
view3.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"Title3"
image:nil
tag:3];
view4.tabBarItem =
[[UITabBarItem alloc] initWithTitle:#"Title4"
image:nil
tag:4];

In my project I have done so :

add UITabBarControllerDelegate
#interface SCTabController : UITabBarController<UITabBarControllerDelegate>
#end
then add below code in viewDidLoad in SCTabController.m
self.delegate = self;
implement UITabBarControllerDelegate didSelectViewController in SCTabController.m
-(void) tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
//Write your code here
//NSLog(#"%lu", (unsigned long)self.selectedIndex);
UILabel *functionTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 190, 50)];
[functionTitleLabel setTextAlignment:NSTextAlignmentCenter];
switch (self.selectedIndex) {
case 0:
[functionTitleLabel setText:#"title1"];
break;
case 1:
[functionTitleLabel setText:#"title2"];
break;
case 2:
[functionTitleLabel setText:#"title3"];
break;
default:
[functionTitleLabel setText:#"title4"];
break;
}
self.navigationItem.titleView = functionTitleLabel;
}

Using a UITabBarController and a UINavigationController together

What is the best practice or good way to have with 2 tabs behave like a UINavigationController when clicking through views after the tab bar views.
Do I make a UINavigationController for each tab?
The tab bar is created like so:
// Create the tab bar text and images
AViewController *viewA = [[AViewController alloc] init];
BViewController *viewB = [[BViewController alloc] init];
UITabBarItem *tabA = [[UITabBarItem alloc] initWithTitle:#"A" image:[UIImage imageNamed:#"a.png"] tag:1];
UITabBarItem *tabB = [[UITabBarItem alloc] initWithTitle:#"B" image:[UIImage imageNamed:#"b.png"] tag:2]
viewA.tabBarItem = tabA;
viewB.tabBarItem = tabB;
NSArray* controllers = [NSArray arrayWithObjects:viewA, viewB, nil];
self.viewControllers = controllers;
For navigation you need to create UINavigationController for each like this
Updated : Try now
AViewController *viewA = [[AViewController alloc] init];
BViewController *viewB = [[BViewController alloc] init];
UINavigationController *navA = [[UINavigationController alloc]initWithRootViewController:viewA];
UINavigationController *navB = [[UINavigationController alloc]initWithRootViewController:viewA];
UITabBarItem *tabA = [[UITabBarItem alloc] initWithTitle:#"A" image:[UIImage imageNamed:#"a.png"] tag:1];
UITabBarItem *tabB = [[UITabBarItem alloc] initWithTitle:#"B" image:[UIImage imageNamed:#"b.png"] tag:2]
tabA.tabBarItem = tabA;
tabB.tabBarItem = tabB;
NSArray* controllers = [NSArray arrayWithObjects:navA, navB, nil];
self.viewControllers = controllers;

iOS 7: different navigation items for tab bar controller

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.

iOS 7 - TabBarController does not have text label

I am trying to create an application with a UITabBarController. I have followed several tutorials online and it seems like I'm missing something since my UITabBarController does not have text but you can switch from one View to another.
Here is my didFinishWithLaunchingOptions function:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.tabController = [[UITabBarController alloc] init];
UIViewController *viewController1 = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
ListViewController *listVC = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
self.tabController.viewControllers = [[NSArray alloc] initWithObjects:viewController1, listVC, nil];
self.window.rootViewController = self.tabController;
[self.window makeKeyAndVisible];
[self createCopyOfDatabaseIfNeeded];
return YES;
}
What am I missing out on?
You need to set the tab bar image and title of each view controller:
self.tabController = [[UITabBarController alloc] init];
UIViewController *viewController1 = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
ListViewController *listVC = [[ListViewController alloc] initWithStyle:UITableViewStylePlain];
viewController1.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"VC1" image:[UIImage imageNamed:#"tab_ yourViewController.png"] tag:0];
listVC.tabBarItem = [[UITabBarItem alloc] initWithTitle:#"listVC" image:[UIImage imageNamed:#"tab_listvc.png"] tag:1];
self.tabController.viewControllers = [[NSArray alloc] initWithObjects:viewController1, listVC, nil];
It's also possible (and often preferred) to set the tabBarItem for each view controller in viewDidLoad, I.e.:
- (void)viewDidLoad
{
[super viewDidLoad]; // Be a good citizen!
self.tabBarItem = [[UITabBarItem alloc] init...];
...
You can set tabbar item for each view with code
UITabBar *tabBar = self. tabController.tabBar;
UITabBarItem *tabBarItem0 = [tabBar.items objectAtIndex:0];
UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:1];
[tabBarItem0 setTitle:#"title1"];
[tabBarItem0 setImage:[UIImage imageNamed:#"img1"]];
[tabBarItem1 setTitle:#"title2"];
[tabBarItem1 setImage:[UIImage imageNamed:#"img2"]];
self.window.rootViewController = self.tabController;
[self.window makeKeyAndVisible];

iPad UIPopover presented over UIBarButtomItem covers BarButtomItem?

I have UIBarButtomItem that shows popover when pressed:
//add help button
self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(#"Help", #"Help") style:UIBarButtonItemStylePlain target:self action:#selector(showInfoBubble:)] autorelease];
infoBubblePopOverVisible = NO;
self.infoBubblePopOverController = nil;
Here is show info bubble:
- (void) showInfoBubble: (id) sender {
[self dismissPopoverControllerExplicitly];
if (self.infoBubblePopOverController == nil) {
InfoBubbleViewController *controller = [[InfoBubbleViewController alloc] initWithNibName:#"InfoBubbleViewController" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:controller];
self.infoBubblePopOverController = [[UIPopoverController alloc] initWithContentViewController:navigationController];
[controller release];
[navigationController release];
}
//present popOverController
[self.infoBubblePopOverController presentPopoverFromBarButtonItem:self.navigationItem.leftBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
infoBubblePopOverVisible = YES;
}
But when presented popover is presented partially covering barbuttomitem:
How can i fix this?

Toolbar + Navigation Bar + Segmented Control?

I'm trying to find a way to layout an application that includes a tab bar on the bottom, a navigation bar on the top, and a row of buttons on the navigation bar that switches views (on the first tab).
I've drawn a very rough sketch (sorry!), but I hope it illustrates the intent.
On the bottom, there are two tabs (tab1, and tab2).
When Tab1 is selected, the navigation bar will have 3 buttons that will show different views (tab1_1, tab1_2, tab1_3).
When Tab2 is selected, the navigation bar won't show any buttons, but rather some simple text.
At this point, I have the following scheme in my application delegate's didFinishLaunchingWithOptions:
UIViewController *viewController1 = [[Tab1_ViewController alloc] initWithNibName:#"Tab1_ViewController" bundle:nil];
UIViewController *viewController2 = [[Tab2_ViewController alloc] initWithNibName:#"Tab2_ViewController" bundle:nil];
tab1NavController = [[UINavigationController alloc] initWithRootViewController:viewController1];
tab2NavController = [[UINavigationController alloc] initWithRootViewController:viewController2];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:tab1NavController, tab2NavController, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
I was wondering if I need to redo how I'm doing things in order to achieve the layout as in the picture.
Any help would be appreciated, thank you!
I have done this for my current project...i hope this will help you....
At first take UITabbarController at your first viewController [first sketch you have given]
For your first view use this code....
- (void)viewDidLoad {
[super viewDidLoad];
dashBoardView = [[DashboardViewController alloc] initWithNibName:#"DashboardViewController" bundle:nil];
dashBoardView.title = #"dashBoardView";
UINavigationController *mydashboarController = [[[UINavigationController alloc] initWithRootViewController:dashBoardView] autorelease];
mydashboarController.navigationBar.barStyle = UIBarStyleBlack;
[listOfViewControllers addObject:mydashboarController];
[dashBoardView release];
ordersView = [[OrdersViewController alloc] initWithNibName:#"OrdersViewController" bundle:nil];
ordersView.title = #"ordersView";
UINavigationController *myorderController = [[[UINavigationController alloc] initWithRootViewController:ordersView] autorelease];
myorderController.navigationBar.barStyle = UIBarStyleBlack;
[listOfViewControllers addObject:myorderController];
[ordersView release];
orderList = [[OrderListViewController alloc] initWithNibName:#"OrderListViewController" bundle:nil];
orderList.title = #"orderList";
UINavigationController *myorderListController = [[[UINavigationController alloc] initWithRootViewController:orderList] autorelease];
myorderListController.navigationBar.barStyle = UIBarStyleBlack;
[listOfViewControllers addObject:myorderListController];
[orderList release];
productView = [[ProductViewController alloc] initWithNibName:#"ProductViewController" bundle:nil];
productView.title = #"productView";
UINavigationController *myproductController = [[[UINavigationController alloc] initWithRootViewController:productView] autorelease];
[listOfViewControllers addObject:myproductController];
[productView release];
[self.tabBarController setViewControllers:listOfViewControllers animated:YES];
NSArray *segmentTextContent = [NSArray arrayWithObjects:NSLocalizedString(#"Dashboard", #""),NSLocalizedString(#"Order", #""),
NSLocalizedString(#"Product", #""),NSLocalizedString(#"More", #""),
nil];
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentTextContent];
segmentedControl.selectedSegmentIndex = 0;
segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleWidth;
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.frame = CGRectMake(0, 0, 400, 40);
[segmentedControl addTarget:self action:#selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
//defaultTintColor = [segmentedControl.tintColor retain]; // keep track of this for later
segmentedControl.tintColor = [UIColor colorWithHue:8.0 saturation:8.0 brightness:8.0 alpha:1.0];
segmentedControl.alpha = 0.8;
self.navigationItem.titleView = segmentedControl;
[segmentedControl release];
}
If it is not clear to you then please knock...
