Working on a tabbed ipad application. My program builds but fails to launch with the error given below on this line from the AppDelegate.m,
self.tabBarController.viewControllers = #[viewController1, viewController2];
This code has not been edited ie straight from the template and has worked correctly until now. The view controllers seem to initiate, and show valid properties in the inspector when debugging. I am assuming the NSrange error is referring to the self.tabBarController.viewControllers array, maybe that's not true.
Sorry , the error was in my own code, please ignore.

TabBar should not be enable any of tabs untill user clicked on any one of tab,
Below is the code I write to display tab bar, But the problem by defaultly it is showing the first tab.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
PeopleViewController *peopleViewController = [[PeopleViewController alloc] init];
UINavigationController *nav1 = [[UINavigationController alloc] initWithRootViewController:peopleViewController];
[peopleViewController setTitle:#"People"];
EventsViewController *eventsViewController = [[EventsViewController alloc] init];
UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:eventsViewController];
[eventsViewController setTitle:#"Events"];
ActiveViewController *activeViewController = [[ActiveViewController alloc] init];
UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:activeViewController];
[activeViewController setTitle:#"Active"];
MoreViewController *moreViewController = [[MoreViewController alloc] init];
UINavigationController *nav4 = [[UINavigationController alloc] initWithRootViewController:moreViewController];
[moreViewController setTitle:#"More"];
NSArray *arrViewControllers = [[NSArray alloc] initWithObjects:nav1,nav2,nav3,nav4, nil];
[tabBarController setViewControllers:arrViewControllers];
[self.window addSubview:tabBarController.view];
return YES;
}
Create an IBOutlet for the tab bar (e.g. theTabBar) and use following code:
[theTabBar setSelectedItem:nil];
This is default behavior of UITabBarController, by default first tab is selected.
You have the option to make some other tab to be selected at first instance, but cannot change the default selected to null.
[tabBarController setSelectedIndex:0];
By default selected index is 0, this is first tab, you can change it as per your requirement to 1,2,3.
I am having a little hard time here, forgive me if you think my problem is so easy for you.
I am trying to create app using UISplitView. The 1st View on the left is a TableView and the other one on the right is just a normal view.
This is my Code for in AppDelegate.m for UISplitView.
#import "AppDelegate.h"
#import "MasterViewController.h"
#import "DetailViewController.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
MasterViewController *masterVC = [[MasterViewController alloc]init];
DetailViewController *detailVC = [[DetailViewController alloc]init];
UISplitViewController *splitVC = [[UISplitViewController alloc]init];
[splitVC setViewControllers:[NSArray arrayWithObjects:masterVC,detailVC,nil]];
[self.window setRootViewController:splitVC];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
Now, I want to add a Navigation Bar on the TableView, I just don't know how to add if I am using SplitView,but I can when I am using a single TableView.
This is my Code in AppDelegate.m using a single View Application that uses TableView. (This is working)
#import "AppDelegate.h"
#import "ViewController.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
//create UINavigationController
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
Hope you can understand what I'm trying to say. I can't post images since i don't have enough reputation. AGAIN.. The question is "How can I add Navigation Controller in my TableView if I used UISplitView?"
Do you think it will be easy for me if I use storyboards instead of using two XIB files?Hope you can help me.
Thanks in advanced!
try this code
in AppDelegate.h file
UINavigationController *detailNavigationController;
UINavigationController *masterNavigationController;
UISplitViewController *HomeSpilitView;
HomeSpilitViewController *HomeMster;
HomeDetailsViewController *HomeDetailsViewControllers;
in AppDelegate.m file
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
NSMutableArray *array = [NSMutableArray array];
HomeSpilitView = [[[UISplitViewController alloc] init]autorelease];
HomeMster = [[HomeSpilitViewController alloc] initWithNibName:#"HomeSpilitViewController" bundle:nil];
masterNavigationController = [[[UINavigationController alloc] initWithRootViewController:HomeMster] autorelease];
HomeMster.title=#"Title home";
masterNavigationController.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
[array addObject:masterNavigationController];
HomeDetailsViewController *HomeDetailsViewControllers = [[HomeDetailsViewController alloc] initWithNibName:#"HomeDetailsViewController" bundle:nil];
detailNavigationController = [[[UINavigationController alloc] initWithRootViewController:HomeDetailsViewControllers] autorelease];
detailNavigationController.navigationBar.tintColor =[UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:0.1];
HomeDetailsViewControllers.title=#"details title";
HomeMster.objHomeDetailsViewcontroller=HomeDetailsViewControllers;
HomeSpilitView.delegate = HomeDetailsViewControllers;
[array addObject:detailNavigationController];
[HomeSpilitView setViewControllers:array];
[self.window setRootViewController:HomeSpilitView];
[self.window makeKeyAndVisible];
return YES;
}
I am fairly new to xcode so apologies if I am asking bad questions. My issue is that I have created a tabbed application but would like a login screen to show before the tabs display. There a lots of posts about this and the consensus is that you need to get your tabBarController to present a view controller. This makes sense but for some reason my app is not displaying the login screen. I'm going to paste my appDelegate.m code below. Any help would be much appreciated.
Tks

sleep(3);
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
LoginViewController *loginViewController = [[[LoginViewController alloc] initWithNibName:#"LoginViewController" bundle:nil] autorelease];
UIViewController *viewController1 = [[[SecondViewController alloc] initWithNibName:#"FirstViewController" bundle:nil] autorelease];
UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil] autorelease];

self.window.rootViewController = self.tabBarController;
[loginViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[_tabBarController presentViewController:loginViewController animated:YES completion:nil];
[self.window makeKeyAndVisible];
return YES;
}
You should do the presentation from the controller in the first tab (assuming that's the controller you want to show after the login screen is dismissed). Do the presentation from the viewDidAppear method with the animated argument set to NO.
Here my code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
CSDisplayPlaza *displayPlaza = [[CSDisplayPlaza alloc] initWithNibName:#"CSDisplayPlaza" bundle:nil];
[displayPlaza setTabBarItem:[[UITabBarItem alloc] initWithTitle:#"one" image:[UIImage imageNamed:#"displayPlaza"] tag:0]];
UINavigationController *displayPlazaNav = [[UINavigationController alloc] initWithRootViewController:displayPlaza];
CSGameHall *gameHall = [[CSGameHall alloc] initWithNibName:#"CSGameHall" bundle:nil];
[gameHall setTabBarItem:[[UITabBarItem alloc] initWithTitle:#"two" image:[UIImage imageNamed:#"displayPlaza"] tag:1]];
UINavigationController *gameHallNav = [[UINavigationController alloc] initWithRootViewController:gameHall];
CSMyInformation *myInformation = [[CSMyInformation alloc] initWithNibName:#"CSMyInformation" bundle:nil];
[myInformation setTabBarItem:[[UITabBarItem alloc] initWithTitle:#"three" image:[UIImage imageNamed:#"myInformation"] tag:2]];
UINavigationController *myInformationNav = [[UINavigationController alloc] initWithRootViewController:myInformation];
self.tabBarController = [[UITabBarController alloc] init];
[tabBarController setViewControllers:[NSArray arrayWithObjects:displayPlazaNav,gameHallNav,myInformationNav,nil]];
[tabBarController setSelectedViewController:displayPlazaNav];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
In the simulator, cannot display any view controllers. Just a empty tabbar in my simulator. I don't know what happen.
My guess is displayPlaza is nil for some reason. Add log messages after you create every object to verify you in fact created one, and also the tab bar controllers array.
How to insert UINavigationController inside UITabBarController.
Currently I have main UITabBarController with declatarion inside application delegate like this (so tab is main)
self.window.rootViewController = self.tabBarController;
And inside one of tabs I want to insert UINavigationController, and can't get it.
The code is contructed like this:
MainWindow.xib with UITabBarController object with tab typed as UINavigationController (point to NavigationHistory.xib) - screenshot: invalid link
NavigationHistory.xib contains only UINavigationController where view point to History.xib
History.xib have only UITableView element - screenshot: invalid link
And now UIViewController doesn't display my View1 view, and I have no clue why it may be. Maybe you have any clue? or point me to the place where such configuration is done.
I'll answer myself. It's good explained at

[self.window makeKeyAndVisible];
return YES;
}
Add your controller object to UINavigationController, and add that navigationcontroller object to UITabBarController
UINavigationController is a subclass of UIViewController, a UITabBarController expects an array of UIViewControllers (and therefore UINavigationController ); this tells me me that I can give a UITabBarController an array of UINavigationControllers (or sublasses thereof) giving the desired interaction.
