i searched before post my question, but i find nothing useful.
before: i'm a c# developer and i'm doing my first iphone app, don't kill me please!
in my app i have a tabbar controller on the bottom (4 buttons)
each button, is a navigation controller type, its show a navigation bar on the top and in the middle i have a viewcontroller (normally after i load an uitableview)
the mad person that asked me to do this app wants that in the top of the TabBar to show always an image (for advertisement, fixed as 320x50).
so the app should look in this way
< NavigationBar >
ViewController
< UIImage >
< TabBar >
but now is
< NavigationBar >
ViewController
< TabBar >
at first take tabbarview controller then make view controller then set the UIimage then set the navigation bar for the uiview controller
NSMutableArray *listOfViewControllers = [[NSMutableArray alloc] init];
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];
[self.tabBarController setViewControllers:listOfViewControllers animated:YES];
i think it will help you some way...

Titles are not showing after the home screen. I have put UITabBarController after the first screen. First screen hasn't got a UITabBarController. I am not sure the way I have implemented the tab.
I have set titles in every view controller by self.title = #"title". Titles are showing in tab items properly.
AppDelegate.m:
UIViewController *loginView= [[[LoginViewController alloc] initWithNibName:#"LoginViewController" bundle:nil] autorelease];
UINavigationController *loginViewNavController = [[UINavigationController alloc] initWithRootViewController:loginView ];
self.navigationController = loginViewNavController;
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
LoginViewController.m:
-(IBAction)navigateMainMenu:(id)sender{
tabBarController = [[UITabBarController alloc] init];
MyAccountsViewController *vc1 = [[MyAccountsViewController alloc] initWithNibName:#"MyAccountsViewController" bundle:nil];
DepositsViewController *vc2 = [[DepositsViewController alloc] initWithNibName:#"DepositsViewController" bundle:nil];
MoreViewController *vc3 = [[MoreViewController alloc] initWithNibName:#"MoreViewController" bundle:nil];
PayTransViewController *vc4 = [[PayTransViewController alloc]init];
NSArray* controllers = [NSArray arrayWithObjects:vc1,vc4, vc2, vc3, nil];
tabBarController.viewControllers = controllers;
[self.navigationController pushViewController:tabBarController animated:YES];
[mainMenuViewController release];
If you set self.title = #"Title". This title will set in navController title. But In your TabBarController, every items are ViewController. Not an navigationController.
Issue: What you release in this line
[mainMenuViewController release];
mostly display title with bellow trickes :-
1. Self.title=#"Your Titile";
2. self.navigationItem.title=#"your Title";
3. when you using UItabBarController you can set Particular Viewcontroller as par your code Title like:-
vc1.title=#"your Title";
vc2.title=#"your Title";
vc3.title=#"your Title";
vc4.title=#"your Title";
I suggest you not you use tabbarcontroller inside a navigationcontroller. If you are using tabbarcontroller it should be the rootViewcontroller.
My program is not supporting the UIInterfaceOrientation. Program will not support the UIInterfaceOrientation after I add the UITabBarItem.Please give a solution. Also I added the navigationController.
Here is my code.
-(void) applicationDidFinishLaunching:(UIApplication *)application {
//I create my navigation Controller
//UINavigationController *navigationController;
//I create my TabBar controlelr
tabBarController = [[UITabBarController alloc] init];
// Icreate the array that will contain all the View controlelr
NSMutableArray *localControllersArray = [[NSMutableArray alloc] initWithCapacity:2];
// I create the view controller attached to the first item in the TabBar
sivajitvViewController *firstViewController;
firstViewController = [[sivajitvViewController alloc]init];
navigationController = [[UINavigationController alloc] initWithRootViewController:firstViewController];
//[navigationController.tabBarItem initWithTabBarSystemItem:UITabBarSystemItemFavorites tag:1];
firstViewController.navigationItem.title=#"Gallery";
//viewController.tabBarItem.image = [UIImage imageNamed:#"natural.jpg"];
navigationController.tabBarItem.image = [UIImage imageNamed:#"Gallery.png"];
navigationController.tabBarItem.title = #"Gallery";
//navigationController.headerTitle = #"Some Title";
[localControllersArray addObject:navigationController];
[navigationController release];
[firstViewController release];
// I create the view controller attached to the second item in the TabBar
SecondViewController *secondViewController;
secondViewController = [[SecondViewController alloc] init];
navigationController = [[UINavigationController alloc] initWithRootViewController:secondViewController];
//[navigationController.tabBarItem initWithTabBarSystemItem:UITabBarSystemItemContacts tag:2];
navigationController.tabBarItem.image = [UIImage imageNamed:#"News.png"];
navigationController.tabBarItem.title = #"News";
[localControllersArray addObject:navigationController];
[navigationController release];
[secondViewController release];
// load up our tab bar controller with the view controllers
tabBarController.viewControllers = localControllersArray;
// release the array because the tab bar controller now has it
[localControllersArray release];
// add the tabBarController as a subview in the window
[window addSubview:tabBarController.view];
// need this last line to display the window (and tab bar controller)
[window makeKeyAndVisible];
}
If you have UITabBarController, all the tabs should support your interface orientation. So if you have 3 tabs and 2 of them support portrait and landscape, but the last one supports only portrait, you application will never turn to landscape.
i need to implement a multiview app really complex to me and i need some advice. The multiview app is something like:
First view: Normal UIViewController with one button, when i push it go to second view
Second view(aka mainview): a Windows with Tab Bar with 2 tabbar item who switch between:
Second view A: Normal UIViewController with some elements
Second view B: UITableViewController
Can someone give me an advice where to start reading or some examples?
thx
my advice is to read sample code form apple there you can also find coding how to s so good luck, or you can find example codes all over the stack just search. for example navigation based app:
UINavigationController doesn't work in a the moreNavigationController of a UITabBarController
or simple transition:
SecondViewController *screen = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:screen animated:YES];
[screen release];
hope it helps bye

You need to start with view based application. And then create a UITabbarController in you appDelegate file.
Appdelegate.h
UITabBarController *tabBarController;
// set properties
Appdelegate.m
// Synthsize
tabBarController = [[UITabBarController alloc] init];
tabBarController.delegate=self;
//Adding Search,Nearby,Map,AboutUs,Favorites Tabs to tabBarController
Search * search = [[Search alloc] init];
UINavigationController *searchNav = [[UINavigationController alloc] initWithRootViewController:search];
Nearby* nearby = [[Nearby alloc] init];
UINavigationController *nearbyNav = [[UINavigationController alloc] initWithRootViewController:nearby];
Map* map = [[Map alloc] init];
UINavigationController *mapNav = [[UINavigationController alloc] initWithRootViewController:map];
AboutUs* aboutUs = [[AboutUs alloc] init];
UINavigationController *aboutUsNav = [[UINavigationController alloc] initWithRootViewController:aboutUs];
Favorites* favorites = [[Favorites alloc] init];
UINavigationController *favoritesNav = [[UINavigationController alloc] initWithRootViewController:favorites];
NSArray* controllers = [NSArray arrayWithObjects:searchNav,nearbyNav,mapNav,aboutUsNav,favoritesNav, nil];
tabBarController.viewControllers = controllers;
[window addSubview:tabBarController.view];
You can accordingly manage in which tab you want to place navigation controller or only a view controller.
Then in each of the view controllers mentioned above you need to implement
- (id)init {}
in which you can set Tab name and image.
i created TAb bar programatically in this manner
UITabBarController *tabBarController = [[UITabBarController alloc] init];
contacts *vc1 = [[contacts alloc]init];
vc1.tabBarItem.image=[UIImage imageNamed:#"contacts.png"];
search* vc2 = [[search alloc] init];
vc2.tabBarItem.image=[UIImage imageNamed:#"search.png"];
a1* vc3 = [[a1 alloc] init];
a2 *vc4 = [[a2 alloc] init];
a3 *vc5 = [[a3 alloc] init];
NSArray* controllers = [NSArray arrayWithObjects:vc1, vc2,vc3,vc4,vc5, nil];
tabBarController.viewControllers = controllers;
[self.view addSubview:detailNavCont];
// Add the tab bar controller's current view as a subview of the window
[self.view addSubview:tabBarController.view];
What i want to accomplish is, i want to assign images to tab bar, firstly i tried on first 2 tabs, is showing a blue block instead of image.
secondly, when we create tab bar through Interface builder, there are custom tab bar item, like, contacts, search, bookmark ,compose etc.
so, if i want to assign contacts or search image to my tab bar items,which looks like the one in IB, how can i do it??
regards
Try something like this
tabBars = [[UITabBarController alloc] init];
NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:4];
HomeTabViewController *ptr_homeTab;
ptr_homeTab = [[HomeTabViewController alloc]initWithNibName:#"HomeTabViewController" bundle:nil];
UINavigationController *homeNavBar=[[UINavigationController alloc]initWithRootViewController:ptr_homeTab];
homeNavBar.tabBarItem.title=#"Home";
homeNavBar.tabBarItem.image=[UIImage imageNamed:#"home.png"];
[ptr_homeTab release];
myHospitalviewController=[[MyHospitalViewController alloc]initWithNibName:#"MyHospitalViewController" bundle:nil];
UINavigationController *myHospitalNavBar=[[UINavigationController alloc]initWithRootViewController:myHospitalviewController];
myHospitalNavBar.title=#"My Hospital";
myHospitalNavBar.tabBarItem.image=[UIImage imageNamed:#"myhospital.png"];
[myHospitalviewController release];
viewController = [[TreatMentiViewController alloc]initWithNibName:#"TreatMentiViewController" bundle:nil];
UINavigationController *hospitalNavBar=[[UINavigationController alloc]initWithRootViewController:viewController];
hospitalNavBar.tabBarItem.title=#"Hospital";
hospitalNavBar.tabBarItem.image=[UIImage imageNamed:#"hospital.png"];
[viewController release];
PersonalMedicineViewController *ptr_PersonalMedicine = [[PersonalMedicineViewController alloc] initWithNibName:#"PersonalMedicineViewController" bundle:nil];
UINavigationController *managerNavBar=[[UINavigationController alloc]initWithRootViewController:ptr_PersonalMedicine];
managerNavBar.tabBarItem.title=#"Manager";
managerNavBar.tabBarItem.image=[UIImage imageNamed:#"manager.png"];
[ptr_PersonalMedicine release];
[localViewControllersArray addObject:homeNavBar];
[localViewControllersArray addObject:hospitalNavBar];
[localViewControllersArray addObject:myHospitalNavBar];
[localViewControllersArray addObject:managerNavBar];
[homeNavBar release];
[hospitalNavBar release];
[myHospitalNavBar release];
[managerNavBar release];
tabBars.viewControllers = localViewControllersArray;
tabBars.view.autoresizingMask==(UIViewAutoresizingFlexibleHeight);
[localViewControllersArray release];
[window addSubview:tabBars.view];
Your images need to have a proper mask. You should save as png.
I've currently got a UITabBar with 5 screens calling UIViews. That part works fine but I want to put in a UINavigationController in a couple of them. I have found a few tutorials that work fine but all of them implement it in IB and I want to avoid that if possible.
I'm lost as to where to implement the UINavigationController, should I do it in the App Delegate with the UITabBar and call the navigation controller from the UIView or should I create it in the UIView class?
I've tried about 8 different ways and always ends up with either the Navbar not working, no nav bar at all or the app crashing.
Currently I create the tab bar like this:
tabBarController = [[UITabBarController alloc] init];
ScreenA *screenA = [[ScreenA alloc] initWithNibName:#"ScreenA" bundle:nil];
//more here
tabBarController.viewControllers = [NSArray arrayWithObjects:screenA, ...., nil];
[window addSubview:tabBarController.view];
And in the initWithNibName I have this:
self.title = #"Screen A";
self.tabBarItem.image = [UIImage imageNamed:#"someImage.png"];
Ok, do it like this...
tabBarController = [[UITabBarController alloc] init];
searchTableViewController = [[SearchTableViewController alloc] init];
UINavigationController *searchTableNavController = [[[UINavigationController alloc] initWithRootViewController:searchTableViewController] autorelease];
[searchTableViewController release];
searchMapViewController = [[SearchMapViewController alloc] init];
UINavigationController *mapTableNavController = [[[UINavigationController alloc] initWithRootViewController:searchMapViewController] autorelease];
[searchMapViewController release];
tabBarController.viewControllers = [NSArray arrayWithObjects:searchTableNavController, mapTableNavController, nil];
