I have searched a lot about this topic and I can't get this code work. When I execute it, it only shows my test NSLog but the code to go from one view to another doesn't do anything. Here you have the following code:
//FirstViewController.h
#import <UIKit/UIKit.h>
#import "StationDetailsViewController.h"
#interface FirstViewController : UIViewController{
NSArray *ListaEstaciones;
NSArray *ListaID;
}
#property (nonatomic, retain) NSArray *ListaEstaciones;
#property (nonatomic, retain) NSArray *ListaID;
#end
//FirstViewController.m
#import "FirstViewController.h"
#import "StationDetailsViewController.h"
#implementation FirstViewController
#synthesize ListaEstaciones;
#synthesize ListaID;
//...
- (void)tableView: (UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSLog(#"Pushing...");
StationDetailsViewController *controller = [[StationDetailsViewController alloc] initWithNibName:#"StationDetailsViewController" bundle:nil];
[[self navigationController] pushViewController:controller animated:YES];
[controller release], controller = nil;
}
#end
I have tried lots of tutorials and my book but I don't know what is wrong. Thanks a lot, guys.
EDIT: Reading your answers I found that the error is on AppDelegate.m where rootViewController is defined.
//AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1 = [[FirstViewController alloc] initWithNibName:#"FirstViewController" bundle:nil];
UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
UIViewController *viewController3 = [[ThirdViewController alloc] initWithNibName:#"ThirdViewController" bundle:nil];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, viewController3, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
I don't know what to edit here to make this:
[[self navigationController] pushViewController:controller animated:YES];
work properly.
i think the problem is in [self navigationController] .. put a break point on this line of code and probaly you will find its value = nil cuz of that you are not having your detail controller .. you could solve this like that UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:yourMainViewControllerInstance];
This The appDelegate Code :
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
UIViewController *firstViewController = [[[FirstViewController alloc] initWithNibName:#"FBConFirstViewController" bundle:nil] autorelease];
UIViewController *secondViewController = [[[SecondViewController alloc] initWithNibName:#"FBConSecondViewController" bundle:nil] autorelease];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
UINavigationController *nav = [[[UINavigationController alloc] initWithRootViewController:firstViewController]autorelease];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:nav, secondViewController, nil];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
I guess there is some problem either with datasource and delegate settings or your navigation controller.

I implemented the SplitView in my app as follow.
AppDelegate.h
#property (nonatomic, strong) IBOutlet UISplitViewController *splitViewController;
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
LeftsideViewController *masterViewController = [[LeftsideViewController alloc] initWithNibName:#"LeftsideViewController" bundle:nil] ;
UINavigationController *masterNavigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController] ;
HomeViewController *detailViewController = [[HomeViewController alloc] initWithNibName:#"HomeViewController_iPad" bundle:nil];
UINavigationController *detailNavigationController = [[UINavigationController alloc] initWithRootViewController:detailViewController];
masterViewController.homeViewController = detailViewController;
self.splitViewController = [[UISplitViewController alloc] init] ;
[self.splitViewController.view setBackgroundColor:[UIColor blackColor]];
self.splitViewController.delegate = detailViewController;
self.splitViewController.viewControllers=[NSArray arrayWithObjects:masterNavigationController,detailNavigationController,nil];
self.window.rootViewController = self.splitViewController;
NSLog(#"VIEWs %#",[self.window subviews]);
[self.window makeKeyAndVisible];
return YES;
}
Problem
It is working fine in ios 6.
But in ios 7 it shows the some view which i did not included.
See my following image & the extra view is in Pink Color.
float systemversion=[[[UIDevice currentDevice]systemVersion]floatValue];
if(systemversion>=7.0f)
{
self.edgesForExtendedLayout=UIRectEdgeNone;
}
Try this code
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
The title pretty much says it all. I'm trying to create an interface where after connecting with Facebook, the window loads up my HomeViewController (my initially selected UITabBarItem). Although, I do not want the UINavigationBar that comes through as I have set the HomeViewController as the LoginViewController's root view. I have different navigation bar items for each view, so defaulting to that one won't work. I have this code now.
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.mainViewController = [[HomeViewController alloc] initWithNibName:#"HomeViewController" bundle:nil];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.mainViewController];
self.window.rootViewController = self.navigationController;
}
Create your custom tabbar Class add it in appDelegate
appDelegate.m
self.tabBarVC = [[[TabBarVC alloc] init] autorelease];
self.navController = [[[UINavigationController alloc]initWithRootViewController:self.tabBarVC]autorelease];
self.window.rootViewController = self.navController;
TabBarVC.h
#import <UIKit/UIKit.h>
#interface TabBarVC : UITabBarController
#end
TabBarVC.m
#import "TabBarVC.h"
#import "ViewController1.h"
#import "ViewController2.h"
#implementation TabBarVC
- (void)viewDidLoad
{
[super viewDidLoad];
UIViewController *vc1 = [[UIViewController alloc] initWithNibName:#"ViewController1" bundle:nil];
UIViewController *vc2 = [[UIViewController alloc] initWithNibName:#"ViewController2" bundle:nil];
[self setViewControllers:[NSArray arrayWithObjects:vc1,vc2, nil]];
}
#end

I am learning Xcode and working for IOS developer as trainee. I am using Xcode 4.2 and Lion OS. My targeted OS will be ios 3+ version. Somebody told me that using storyboard gives the problem for older version. So i want to develop without using Storyboard for navigationController. Help me out, cause all the old tutorials does not help at all, cause there are lots of missmatch due to change in xcode version.
Help me please.
For creating a navigation controller, select a Single View Application for your project template. In the AppDelegate.h, create an instance of the UINavigationController. In the AppDelegate.m file, do this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
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];
navigationController = [[UINavigationController alloc] initWithRootViewController:(UIViewController*)viewController];
[window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}
This will give the base as a navigation controller. You can add other views on this using
[self.navigationController pushViewController:newViewController animated:YES];
While you creating new project
there is check marks for use storyboard just remove it from there.then move ahead as you are moving before.
Add this to your AppDelegate, and play around with them. See what happens and you will learn.
#interface AppDelegate : UIResponder <UIApplicationDelegate, UITabBarControllerDelegate>{
}
#property (strong, nonatomic) UIWindow *window;
#property (strong, nonatomic) UITabBarController *tabBarController;
#end
//*****************************************//
.m file
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1 = [[Categories alloc] initWithNibName:#"Categories" bundle:nil];
UIViewController *viewController2 = [[Coupons alloc] initWithNibName:#"Coupons" bundle:nil];
UIViewController *viewController3 = [[Favourites alloc] initWithNibName:#"Favourites" bundle:nil];
UIViewController *viewController4 = [[AroundMe alloc] initWithNibName:#"AroundMe" bundle:nil];
viewController2.title = NSLocalizedString(#"Coupons", #"Coupons");
viewController2.tabBarItem.image = [UIImage imageNamed:#"coupons.png"];
viewController3.title = NSLocalizedString(#"Favourites", #"Favourites");
viewController3.tabBarItem.image = [UIImage imageNamed:#"favourites.png"];
// UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UINavigationController *navController1 = [[UINavigationController alloc] initWithRootViewController:viewController1];
UINavigationController *navController2 = [[UINavigationController alloc] initWithRootViewController:viewController2];
UINavigationController *navController3 = [[UINavigationController alloc] initWithRootViewController:viewController3];
UINavigationController *navController4 = [[UINavigationController alloc] initWithRootViewController:viewController4];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:navController1,navController2, navController3, navController4, nil];
self.window.rootViewController = self.tabBarController;
can we use UITab bar controller in view base application thank you
Yes you can.
you can look at the "TheElements" example that apple provides.
you can find it here:
https://developer.apple.com/library/ios/#samplecode/TheElements/Introduction/Intro.html
look at the app delegate.
its very strait forward example.
for you request i tried to make a simple example:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self setupPortraitUserInterface];
return YES;
}
- (UINavigationController *)AchievementsControllerWrappingViewController:(NSInteger*)tabIndex{
switch(tabIndex){
case 0:
FirstViewController *theViewController;
theViewController = [[FirstViewController alloc] init];
break;
case 1:
SecondViewController *theViewController;
theViewController = [[SecondViewController alloc] init];
break;
}
UINavigationController *theNavigationController;
theNavigationController = [[UINavigationController alloc] initWithRootViewController:theViewController];
[theViewController release];
return theNavigationController;
}
- (void)setupPortraitUserInterface {
UINavigationController *localNavigationController;
UIWindow *localWindow;
localWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window = localWindow;
[localWindow release];
tabBarController = [[UITabBarController alloc] init];
NSMutableArray *localViewControllersArray = [[NSMutableArray alloc] initWithCapacity:2];
for(int i=0;i<2;i++){
localNavigationController = [self AchievementsControllerWrappingViewController:i];
[localViewControllersArray addObject:localNavigationController];
[localNavigationController release];
}
tabBarController.viewControllers = localViewControllersArray;
[localViewControllersArray release];
[window addSubview:tabBarController.view];
[window makeKeyAndVisible];
}
i am not next to xCode and i did it with text edit, so please check it when you use it.
shani
Yes we can..
For that you have to create UITabBarViewController and its Object then refrence it with you Application..like :
in your AppDelegate.h
#interface youAppDelegate.h : UIApplicationDelegate {
UIWindow *window;
YourViewController *viewController;
// Declare Your TabBarController Here
UITabBarController *tabBar;
}
#property (nonautomic, retain) IBOutlet UIWindow *window;
#property (nonautomic, retain) IBOutlet TabBarViewController *tabBar;
#end
in you implementation file's ApplicationDidFinish Launching add the following Code
viewController = [[YourViewController alloc] init];
[viewController addSubView:tabBar];
[self.window addSubView:viewController];
In interface builder you have to add the TabBarController to your MainWindow and relate it with the IBOutLet. Give what ever view you want to display in tabBar.
enjoy..
