I have created a custom navigation controller in appDelegate :
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
poemsView = [[[PoemsViewController alloc]initWithNibName:#"PoemsViewController" bundle:nil] autorelease];
self.navigationController = [[[UINavigationController alloc] initWithRootViewController:poemsView] autorelease];
self.navigationController.navigationBarHidden = YES;
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] autorelease];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
so the problem is I need my app lunches from viewController , but if I set my viewController as rootviewController , my navigation controller does not push navigation and vice versa , if set my navigation controller as a root , app does not load from menus or main view controller .
Why you Creating Poemsview as rootviewcontroller of Navigation Controller ?
if You Want To Load ViewController First Then use the following Code.
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] autorelease];
poemsView = [[[PoemsViewController alloc]initWithNibName:#"PoemsViewController" bundle:nil] autorelease];
self.navigationController = [[[UINavigationController alloc] initWithRootViewController:self.viewController] autorelease];
self.navigationController.navigationBarHidden = YES;
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
You Can Create Another Navigation Controller as a Sub-class of Viewcontroller.
In your Poem Button Action Add The Following :
// Create a regular view controller.
PoemViewController *modalViewController = [[[PoemViewController alloc] initWithNibName:#"PoemViewController" bundle:nil] autorelease];
// Create a navigation controller containing the view controller.
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:modalViewController];
// Present the navigation controller as a modal view controller on top of an existing navigation controller
[self presentModalViewController:secondNavigationController animated:YES];
Now You can be able push To detail View from Your tableview DidselectRowAtindexpath .

I've been looking at programatically adding a tab bar to my view controller because having a scroll view I can't place it on without it being in the middle of my view. I'm abit confused about how to add it. Does it need to be initiated in my ViewDidLoad method or my AppDelegate?
If I have:
UITabBarController *tabBar = [[UITabBarController alloc] init];
[self.view addSubview:tabBar.view];
[tabBar release];
How can I allocate it to the bottom of my scrollview?
Thanks!
Now in my appDelegate class :
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
UITabBarController *tabBarController = [[UITabBarController alloc] init];
ViewController* vc = [[ViewController alloc] init];
NSArray* controllers = [NSArray arrayWithObjects:vc, tabBarController, nil];
tabBarController.viewControllers = controllers;
[_window addSubview:tabBarController.view];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
It's crashing and not sure if it's a release I'm missing.
Edit:
For anyone else wondering this in Appdelegate.m:
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = #[viewController1, viewController2, viewController3, viewController4];
Take a look at this Documentation given by Apple: ViewControllers.
Sample Code :
- (void)applicationDidFinishLaunching:(UIApplication *)application {
UITabBarController *tabBarController = [[UITabBarController alloc] init];
FirstViewController* vc1 = [[FirstViewController alloc] init];
SecondViewController* vc2 = [[SecondViewController alloc] init];
NSArray* controllers = [NSArray arrayWithObjects:vc1, vc2, nil];
tabBarController.viewControllers = controllers;
// Add the tab bar controller's current view as a subview of the window
[window addSubview:tabBarController.view];
}
I did it this way. I copied this from my App Delegate and it works fine. Basically you add the view controllers to the tab bar then add the tab bar to the window's subview.
Instantiate the instance
iVacationTabBar = [[UITabBarController alloc] init];
However you create the views/view controllers:
UINavigationController *rvc_tools = [[UINavigationController alloc] initWithRootViewController: vc_tools];
UINavigationController *rvc_settings = [[UINavigationController alloc] initWithRootViewController: vc_settings];
UINavigationController *rvc_about = [[UINavigationController alloc] initWithRootViewController: vc_about];
UINavigationController *rvc_currentpage = [[UINavigationController alloc] initWithRootViewController: vc_currentpage];
UINavigationController *rvc_backup = [[UINavigationController alloc] initWithRootViewController:vc_backup];
Add the controllers to the array:
NSArray* controllers = [NSArray arrayWithObjects: rvc_currentpage, rvc_tools,rvc_settings, rvc_backup, rvc_about, nil];
Set the array of view controllers to your tab bar:
[iVacationTabBar setViewControllers: controllers animated:NO];
Add the tab bar to the window's subview.
[_window addSubview:iVacationTabBar.view];
You can not add a UITabbarController on a UIViewController. Instead, on a ViewController you have to show the TabbarController, create a TabbarController, set ViewControllers for it, and add it to a Window.
In my tab based application delegate i added the navigation controller as like the following,
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
UIViewController *viewController3 = [[view1 alloc] initWithNibName:#"view1" bundle:nil];
UIViewController *viewController4 = [[view2 alloc] initWithNibName:#"view2" bundle:nil];
UIViewController *viewController5 = [[view3 alloc] initWithNibName:#"view3" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = #[viewController1, viewController2,viewController3,viewController4,viewController5];
navigationController=[[UINavigationController alloc]initWithRootViewController:self.tabBarController];
[self.window addSubview:[navigationController view]];
self.window.rootViewController = self.navigationController;
i would not be able to added the title in each view. While adding it doesn showing the title?Pls help me to resolve this issue
use bellow code...
Here i add UINavigationController to every tab and also assign title for tab and also for UINavigationBar like bellow...
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
UIViewController *viewController1, *viewController2, *viewController3, *viewController4, *viewController5;
UINavigationController *navviewController1 , *navviewController2, *navviewController3, *navviewController4, *navviewController5;
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
viewController1 = [[[YourViewController1 alloc] initWithNibName:#"YourViewController1" bundle:nil] autorelease];
navviewController1=[[UINavigationController alloc]initWithRootViewController:viewController1];
navviewController1.title = #"Home";
// navviewController1.navigationBarHidden=YES;
viewController2 = [[[YourViewController2 alloc] initWithNibName:#"YourViewController2" bundle:nil] autorelease];
navviewController2=[[UINavigationController alloc]initWithRootViewController:viewController2];
// navviewController2.navigationBarHidden=YES;
navviewController2.title = #"HowItsWork";
viewController3 = [[[YourViewController3 alloc] initWithNibName:#"YourViewController3" bundle:nil] autorelease];
navviewController3=[[UINavigationController alloc]initWithRootViewController:viewController3];
// navviewController3.navigationBarHidden=YES;
navviewController3.title = #"Join Us";
viewController4 = [[[YourViewController4 alloc] initWithNibName:#"YourViewController4" bundle:nil] autorelease];
navviewController4=[[UINavigationController alloc]initWithRootViewController:viewController4];
// navviewController4.navigationBarHidden=YES;
navviewController4.title = #"Become";
viewController5 = [[[YourViewController5 alloc] initWithNibName:#"YourViewController5" bundle:nil] autorelease];
navviewController5=[[UINavigationController alloc]initWithRootViewController:viewController5];
// navviewController4.navigationBarHidden=YES;
navviewController5.title = #"Contact Us";
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navviewController1, navviewController2,navviewController3,navviewController4,navviewController5, nil];
self.window.rootViewController = self.tabBarController;
}
[self.window makeKeyAndVisible];
}
2)OR
Also you can simple assign title in your particular class like bellow...
-(void)viewWillAppear:(BOOL)animated{
self.title = #"yourTitle";
}
i hope this helpful to you...
Go to viewdidload method in every tabbar controller & use line:
navigationController.title=#"hello";
In every viewcontroller viewdidload
self.navigationcontroler.title=#"firstVC";
"title" is the property of UIViewController and UINavigationController is the subclass of UIViewController you can also access it object of UINavigationController, just like navviewController.title = #"myTitle"; and for more detail check Apple Docs. Hope it will help. Cheers
You have added TabBar Controller inside a Navigation Controller so you cannot add title and arises this issue.
Try to add each navigation controller with View controller inside tabbar controller.
I mean add ur ViewController as a root View controller of navigation controller then add to tab Bar controller.
viewController1 = [[[YourViewController1 alloc] initWithNibName:#"YourViewController1" bundle:nil] autorelease];
navviewController1=[[UINavigationController alloc]initWithRootViewController:viewController1];
Now then ad this navigation controller inside to tabbar controller. Do this for all other viewcontrollers
I want to show modal view in the start of the app but it doesn't appear. This is my code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self initDataBase];
CustomerModel *customer = [[[CustomerPersistor alloc] init] getLoggedCustomer];
self.window.rootViewController = self.tabBarController;
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
UIViewController *profileViewController = [[[ProfileViewController alloc] initWithNibName:#"ProfileViewController" bundle:nil] autorelease];
profileViewController.title = #"Profile";
UINavigationController *profileNavigation = [[[UINavigationController alloc] initWithRootViewController:profileViewController] autorelease];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:profileNavigation, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
if(customer == nil) { NSLog(#"HO");
ViewController *login = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
//login.delegate = self.tabBarController.view;
[self.viewController presentModalViewController:[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] animated:YES];
}
return YES;
}
How can I fix it?
First, there doesn't appear to be a self.viewController property that is set, and you're instantiating the same "ViewController" twice. This is all wrong:
ViewController *login = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
//login.delegate = self.tabBarController.view;
[self.viewController presentModalViewController:[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] animated:YES];
Try moving this code to your viewDidLoad of your profileViewController...i.e. let the TabBarController load along with its first tab's view controller.
Initiate an instanse from the model view like this:
modelView = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
Please follow the list below:
Set the viewController model presented style
[modelView setModalPresentationStyle:UIModalPresentationPageSheet];
Then present it using:
[self.viewController presentModalViewController:floorView animated:YES];
Then, set the size and location of the model controller like this:
modelView.view.superview.bounds = CGRectMake(0, 0, 700, 550);//it's important to do this after presentModalViewController
modelView.view.superview.center = self.view.superview.center;//self.view assumes the base view is doing the launching, if not you might need self.view.superview.center etc.
Hope this help you.
I choose the project template as "Single View" .I am trying to push a detail view(UIViewController) on the button click.Button action is firing properly and executing the code [self navigatingController] push......My code is As:
MapDetailViewController *mapDetailViewController = [[MapDetailViewController alloc] init];
[self.navigationController pushViewController:mapDetailViewController animated:YES];
NSLog(#"self.navigation is as %#",self.navigationController);
self.navigationController is null.So i tried to alloc init a local variable of type Navigation Controller and also the variable was able to be non-null(some hex value), still i was unable to push the mapDetailView.
what i am thinking is that i have choosen the wrong template(view based).Should i choose the Navigation-based(Master-detail).Well the below auto generated code is of application delegate:
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] autorelease];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
Should some changes be made here for navigation controller?
Any Suggestion?
Your problem is that you don't even have a navigation controller to do the pushing. Change your code to this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] autorelease];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = nav;
[self.window makeKeyAndVisible];
return YES;
}
In iPhone App ,How to add tab bar controller on some particular view controller Programmatically?
Here the viewcontroller Class is is UITableviewcontroller .
right now if i am adding the tab bar it appears some where in table view. i want to display it on bottom of window and and tableview should scroll separately from Tabbarcontroller
Please help and suggest
Thanks
FirstView *view1 = [[FirstView alloc]init];
SecondView *view2 = [[SecondView alloc] init];
UINavigationController *firstview = [[UINavigationController alloc] initWithRootViewController:view1];
UINavigationController *secondview = [[UINavigationController alloc] initWithRootViewController:view2];
UITabBarController* tabBar = [[UITabBarController alloc] init];
[tabBar setViewControllers:[NSArray arrayWithObjects:view1, view2, nil]];
[tabBar setDelegate:self];
UINavigationController* navigationController = [[UINavigationController alloc] initWithRootViewController:tabBar];
[self.view addSubview:navigationController.view];
Try this. here FirstView, SecondView are the class. if you click the tab, corresponding class (view) will open. And you have declare the tabbar and navigation controller delegate.
first you just select tabbar base application from project template.
now double click on mainwindow.xib its open it in interface builder.
now click on tabbarcontroller and open inspector window.
in above image your are able to see list of viewcontrollers. click on class tab will gives you the option of controller type. see in below image
if your are selecting table view controller then your first controller is table view. and tabbar is not in your view. table is scroll separately.
