I need to add a UINavigationController to a UIViewController,and don't use appDelegate.In my Controller I write like this
OneViewController *oneVC = [[OneViewControlelr alloc] initWithNibName:nil bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:oneVC];
[self presendModalViewController:nav];
and it nothing to found.
It should be
[self presentModalViewController: nav animated:YES];
For more info, please visit UIViewController documentation
Try this :
OneViewController *oneVC = [[OneViewControlelr alloc] initWithNibName:#"OneViewControlelr" bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:oneVC];
[self presentModalViewController: nav animated:YES];
if you dnt want navigationcontroller just try this
OneViewController *oneVC = [[OneViewControlelr alloc] initWithNibName:#"xibname" bundle:nil];
[self presendModalViewController:oneVC animated:YES];
[oneVC release];
if u want navigationController try this code
OneViewController *oneVC = [[OneViewControlelr alloc] initWithNibName:#"xibname" bundle:nil];
UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:oneVC];
[self presendModalViewController:navigationController animated:YES];
[oneVC release];
[navigationController release];
Just do like this in AppDelegate.m file
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
SoapWebServiceViewController *root = [[SoapWebServiceViewController alloc] initWithNibName:nil bundle:nil];
nav = [[UINavigationController alloc] initWithRootViewController:root];
// Add the view controller's view to the window and display.
[self.window addSubview:nav.view];
}
Hope this help U
OneViewController *oneVC = [[OneViewControlelr alloc] initWithNibName:nil bundle:nil];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:oneVC];
AppDelegate *appDelegate=(AppDelegate*)[[UIApplication sharedApplication]delegate];
[[[appDelegate <viewController>]view] removeFromSuperview]; // put UIViewController reference into <viewController>
[[appDelegate window]addSubview:[[appDelegate nav]view]];

i have added tab bar in app delegate. When i pushed the view from one of my view te tab bar got removed. I want that tab bar on pushed view also.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
AudioViewController * audioViewController = [[AudioViewController alloc] initWithNibName:#"AudioViewController" bundle:nil];
audioViewController.title = #"audio";
audioViewController.tabBarItem.image=[UIImage imageNamed:#"audio 30x30.png"];
ViewController *videoViewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
videoViewController.title = #"video";

Check value of this property in the UIViewController you are pushing
#property(nonatomic) BOOL hidesBottomBarWhenPushed
Try this sample code
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
AudioViewController * audioViewController = [[AudioViewController alloc] initWithNibName:#"AudioViewController" bundle:nil];
audioViewController.title = #"audio";
audioViewController.tabBarItem.image=[UIImage imageNamed:#"audio 30x30.png"];
UINavigationController *navaudioViewController = [[UINavigationController alloc] initWithRootViewController:audioViewController];
PlaylistViewController *PlaylistViewControllerObj = [[PlaylistViewController alloc]initWithNibName:#"PlaylistViewController" bundle:nil];
PlaylistViewControllerObj.title = #"Playlist";
PlaylistViewControllerObj.tabBarItem.image=[UIImage imageNamed:#"ko.png"];
UINavigationController *navPlaylistView = [[UINavigationController alloc] initWithRootViewController:PlaylistViewControllerObj];
UITabBarController * myTabbarController = [[UITabBarController alloc] init];
myTabbarController.viewControllers = #[navHomeController,navPlaylistView];
self.window.rootViewController = myTabbarController;
[self.window makeKeyAndVisible];
return YES;
}
Use This Code
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 have an activation page in my app, which is mandatory for every user to activate the app.
Once the app is activated, the user moves to the tabbed bar view.
I have created a tabbed bar application, where from my activationView on click of button I am trying to call the tab bar, I am getting an entire black screen.
- (IBAction)moveToActivateView:(id)sender {
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
UITabBarController *tabBarController = [[UITabBarController alloc]init];
[self.view addSubview:tabBarController.view];
appDelegate.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
self.tabBarController.viewControllers = #[viewController1, viewController2];
appDelegate.window.rootViewController = self.tabBarController;
[appDelegate.window makeKeyAndVisible];}
Hey make your tabBarController's property in appDelegate and assign all ViewController there then call your tabBarController from yourViewController
in AppDelegate.h
#property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
#property (retain, nonatomic) IBOutlet UITabBarController *tabBarController;
in AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self makeTabBar];
[self addInitialVIew];
[self.window makeKeyAndVisible];
return YES;
}
-(void)makeTabBar
{
tabBarController = [[UITabBarController alloc] init];
tabBarController.delegate=self;
FirstViewController *firstVC =[[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UINavigationController *firstNC = [[UINavigationController alloc] initWithRootViewController:firstVC];
firstNC.tabBarItem.title=#"Profile";
firstVC.tabBarController.tabBar.tag = 0;
SecondViewController *secondVC = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
UINavigationController *SecondNavController = [[UINavigationController alloc] initWithRootViewController:secondVC];
SecondNavController.tabBarItem.title = #"Search";
secondVC.tabBarController.tabBar.tag = 1;
NSArray *viewControllers =[[NSArray alloc]initWithObjects:firstNC,SecondNavController, nil];
[tabBarController setViewControllers:viewControllers animated:NO];
}
-(void) addInitialVIew
{
InitialViewController *initialViewController = [[InitialViewController alloc]initWithNibName:#"InitialViewController" bundle:nil];
navigationController = [[UINavigationController alloc]initWithRootViewController:ViewController];
[self.window addSubview:navigationController.view];
}
Now in InitialViewController you can add yourTabBar and remove InitialViewController
- (IBAction)switchToTabBarBtnPress:(id)sender
{
AppDelegate *appdelegte =(AppDelegate*)[[UIApplication sharedApplication]delegate];
[[[appdelegte navigationController] view]removeFromSuperview];
[[appdelegte window]addSubview:[[appdelegte tabBarController]view]];
[[appdelegte tabBarController]setSelectedIndex:0];
}
And Follow my answer
Answer
You want to create dynamic tabbar application to resolve your problem. So you just create the view based application. in the view controller viewdidload method put these code
tabbar1 = [[UITabBarController alloc] init];
artist_tab_obj = [[artist_tab alloc] initWithNibName:#"artist_tab" bundle:nil];
UINavigationController *tabItem1 = [[[UINavigationController alloc] initWithRootViewController: artist_tab_obj] autorelease];
tabItem1.title=#"Artist";
tabItem1.tabBarItem.image=[UIImage imageNamed:#"Icon1.png"];
music_tab_obj = [[music_tab alloc] initWithNibName:#"music_tab" bundle:nil];
UINavigationController *tabItem2 = [[[UINavigationController alloc] initWithRootViewController: music_tab_obj] autorelease];
tabItem2.title=#"Music";
tabItem2.tabBarItem.image=[UIImage imageNamed:#"Icon2.png"];
shout_tab_obj = [[shout_tab alloc] initWithNibName:#"shout_tab" bundle:nil];
UINavigationController *tabItem3 = [[[UINavigationController alloc] initWithRootViewController: shout_tab_obj] autorelease];
tabItem3.title=#"Shout";
tabItem3.tabBarItem.image=[UIImage imageNamed:#"Icon3.png"];
schedule_tab_obj = [[schedule_tab alloc] initWithNibName:#"schedule_tab" bundle:nil];
UINavigationController *tabItem4 = [[[UINavigationController alloc] initWithRootViewController: schedule_tab_obj] autorelease];
tabItem4.title=#"Schedule";
tabItem4.tabBarItem.image=[UIImage imageNamed:#"Icon4.png"];
follow_tab_obj = [[follow_tab alloc] initWithNibName:#"follow_tab" bundle:nil];
UINavigationController *tabItem5 = [[[UINavigationController alloc] initWithRootViewController: follow_tab_obj] autorelease];
tabItem5.title=#"Follower";
tabItem5.tabBarItem.image=[UIImage imageNamed:#"Icon5.png"];
tabbar1.viewControllers = [NSArray arrayWithObjects:tabItem1, tabItem2,tabItem3,tabItem4,tabItem5,nil];
In user acceptation is yes button action call this code.
[self.view insertSubview:tabbar1.view belowSubview: artist_tab_obj.view];
tabbar1.selectedIndex=1;
[self presentModalViewController:tabbar1 animated:YES];
Did you realize that your local varialbe tabBarController is not identical but sort of hides the property self.tabBarController? You create a new UITabBarCotnroller and assign it to your local variable tabBarController, which is accessible from this method only. Then you manipulate (add newly created view controllers) etc to self.tabBarController. Self.tabBarController could easily be nil here or anything else. But it is not the very UITabBarController that you just created.
And it is self.tabBarController (so probably nil) what you assign to the window as rootViewController.
You do add the tabBarController's view as subview to self.view. Besides that I do not know what self acutally is, I don't think is it really nessessary to manually add the tabBar's view as subview. Setting the root view controller (properly) should be enough
I have a UIViewController with two UITableView's in it. When i select a row in the first UITableView it has to push the same UIViewController which doesnt happen.
In UIViewController.h i have,
FirstTableViewController *firstController;
SecondTableViewController *secondController;
In UIViewController.m i have,
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
if (firstController == nil) {
firstController = [[FirstTableViewController alloc] init];
}
if (secondController == nil) {
secondController = [[SecondTableViewController alloc] init];
}
UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithRootViewController:firstController];
firstController.product = self.product;
[firstTable setDataSource:firstController];
[firstTable setDelegate:firstController];
firstNavigationController.view = firstController.tableView;
}
In FirstTableViewController.m, didSelectRowAtIndexPath i have,
[self.searchDisplayController setActive:YES animated:YES];
UIViewController *controller = [[UIViewController alloc]initWithNibName:#"UIViewController" bundle:nil];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.product = prod;
NSLog(#"Navigation controller is %#",self.navigationController); //not null
[[self navigationController]pushViewController:controller animated:YES];
Please help.
EDIT #1: UIViewController is called from the FlipsideViewController of the UtilityApp.
Add a property to your AppDelegate UINavigationController *nav
add this line to AppDelegate.m in application didFinishLaunching method
navigationControl = [[UINavigationController alloc] initWithRootViewController:yourFirst ViewController];
Go to yourFirstViewController, add an UINavigationController *nav property and add these lines to viewDidLoad method
AppDelegate *app = [[UIApplication sharedApplication] delegate];
self.nav = app.nav;
Use this line to push any viewController
[self.nav pushViewController:controller animated:YES];
If you want to show a view controller modally, you should use presentViewController:animated:completion: and not pushViewController:animated:.
[self presentViewController:controller animated:YES completion:nil];
Use this Code in "didSelectRowAtIndexPath"
UIViewController *controller = [[UIViewController alloc]initWithNibName:#"UIViewController" bundle:nil];
[self.navigationController pushViewController:controller animated:YES];
[viewController release];
LoginViewSimpleController *loginViewSimple = [[LoginViewSimpleController alloc]init];
UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:loginViewSimple];
[self setNavigationController:navController];
Have you identify both tableviews ? Can you Post log status here ?
I have an app with a UITabBar and a NavigationController. When I use pushViewController the new ViewController appears with the NavigationController and the back button, but the UITabBarController disappears. I know there are lots of questions here about the same, but any of them have solved my question, maybe because I dont understand the answers given.
Any suggestion?
ActivityViewController *activityController = [[ActivityViewController alloc] initWithNibName:#"ActivityViewController" bundle:nil];
[self.navigationController pushViewController:activityController animated:NO];
That's probably because Your rootViewController (for your main UIWindow) is set to a Navigationcontroller instead of your TabBar.
If you don't want the Tabbar to go away just set it as your root view controller
Do the following in appDidFinishLaunching in your AppDelegate
LoginViewController *loginViewController = [[FirstViewController alloc] init];
UINavigationController *loginNavigationController = [[UINavigationController alloc] loginViewController];
[firstViewController release];
self.window.rootViewController = loginNavigationController;
Then in your Login Page:
- (void)loginSuccessfull
{
FirstViewController *firstViewController = [[FirstViewController alloc] init];
UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithViewController:firstViewController];
[firstViewController release];
SecondViewController *secondViewController = [[SecondViewController alloc] init];
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithViewController:secondViewController];
[secondViewController release];
UITabBarController *tabBarController = [[UITabBarController alloc] init];
[tabBarController setViewControllers:
[NSArray arrayWithObjects:firstNavigationController, secondNavigationController, nil]];
[firstNavigationController release];
[secondNavigationController release];
[self.navigationController pushViewController:tabBarController];
[tabBarController release];
}
If you still need the navigation functionality just wrap your viewControllers inside a UINavigationController, and add the serounding navigationController to the tabBar, instead of the UIViewcontroller
I have a window based app. I added two viewcontrollers and one Tabbarcontroller to that. Now I want to navigate each viewcontroller to next view. I tried but can't find the solution. Can anyone please help me?
When you add the tab bar on window, add like this-
NSMutableArray * viewControllers = [[NSMutableArray alloc]init];
FirstViewController * firstViewController = [[FirstViewController alloc]initWithNibName:#"FirstViewController" bundle:nil];
UINavigationController * nvc = [[UINavigationController alloc] initWithRootViewController:firstViewController];
[firstViewController release];
[viewControllers addObject:nvc];
[nvc release];
SecondViewController * secondViewController = [[SecondViewController alloc]initWithNibName:#"SecondViewController" bundle:nil];
nvc = [[UINavigationController alloc] initWithRootViewController:secondViewController];
[secondViewController release];
[viewControllers addObject:nvc];
[nvc release];
UITabBarController * tabBarController = [[UITabBarController alloc] init];
tabBarController.viewControllers = viewControllers;
[window addSubview:tabBarController.view];
EDIT -
Whenever you want to navigate in any one of the controller. All you need is to call
[self.navigationController pushViewController:anotherViewController animated:YES];
And you will get exactly what you want. :)
UINavigationController *urNavController = [[UINavigationController alloc] initWithRootViewController:rootController];
If you want to show this on the window
[window addSubview:urNavController.view];
use like this
secondViewController *obj=[[[secondViewController alloc] initWithNibName:#"secondViewController" bundle:nil] autorelease];
UINavigationController *navBar=[[UINavigationController alloc] initWithRootViewController:obj];
[self.navigationController pushViewController:navBar animated:YES];
[navBar release];
