If I'll remove [self.window makeKeyAndVisible] , my code works. But I don't understand why do I need to remove makeKeyAndVisible?
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window.rootViewController = self.tabBarController;
if (isLoginScreenNeeded)
{
LoginModalViewController *controller = [[[LoginModalViewController alloc] initWithNibName:#"LoginModal" bundle:[NSBundle mainBundle]] autorelease];
UINavigationController *controllerNav = [[[UINavigationController alloc] initWithRootViewController:controller] autorelease];
[self.window.rootViewController presentModalViewController:controllerNav animated:NO];
//[self.window makeKeyAndVisible]; //controllerNav didn't appeared if I uncomment this string
}
else
{
[self.window makeKeyAndVisible];
}
return YES;
}

Trying to write my first iPhone application using Xcode 5.1. Here is part of my AppDelegate code
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
self.viewController = [self.storyboard instantiateViewControllerWithIdentifier:#"AddViewController"];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:self.viewController];
[self.window addSubview:self.navigationController.view];
[self.window makeKeyAndVisible];
return YES;
}
I have a storyboard called "Main.Storyboard" with Navigation Controller and View Controller.
When I run my app I get SIGABRT error with NSInternalInconsistencyException exception.
Could anyone help me to fix this error?
Thanks.
why you adding subview as a UINavigationController.view and root-view as a view-controller? Your code must be look like this:-
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
self.viewController = [self.storyboard instantiateViewControllerWithIdentifier:#"AddViewController"];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:self.navigationController];
[self.window makeKeyAndVisible];
return YES;
}
And verified that identifier of your viewcontroller is setting correct or not that you are given in above.
Try this
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *storyBord = [UIStoryboard storyboardWithName:#"Main_iPad" bundle:[NSBundle mainBundle]];
self.window.rootViewController = [storyBord instantiateInitialViewController] ;
[self.window makeKeyAndVisible];
return YES;
}
If you use storyboard as a main interface you don't need to setup any code. So you can add UINavigationController to the scene in you storyboard. Then set rootViewController using connection inspector.
Check the video for understanding: link
the code will look like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
return YES;
}
Bellow i have some code that is place in the app delegate.m and is used to create a c between two ViewControllers. The creation of the tab bar works fine but when i select the setting tab there is no view it is just black.
Here is the code:
import "ViewController.h"
#import "Settings.h"
#implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
UITabBarController *tbc = [[UITabBarController alloc]init];
ViewController *vc1 = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
Settings *vc2 = [[Settings alloc]init];
[vc1.tabBarItem setTitle:#"Browse"];
[vc2.tabBarItem setTitle:#"Settings"];
[tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
[self.window setRootViewController:tbc];
return YES;
}
You write the code for setting screen like this
Settings *vc2 = [[Settings alloc]init];
where is the nib file for setting screen ,
Once try like this
UITabBarController *tbc = [[UITabBarController alloc]init];
ViewController *vc1 = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
Settings *vc2 = [[Settings alloc]initWithNibName:#"Settings" bundle:nil];
[vc1.tabBarItem setTitle:#"Browse"];
[vc2.tabBarItem setTitle:#"Settings"];
[tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
[self.window setRootViewController:tbc];
[self.window makeKeyAndVisible];
try with:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITabBarController *tbc = [[UITabBarController alloc]init];
ViewController *vc1 = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
Settings *vc2 = [[Settings alloc]init];
[vc1.tabBarItem setTitle:#"Browse"];
[vc2.tabBarItem setTitle:#"Settings"];
[tbc setViewControllers:[NSArray arrayWithObjects:vc1, vc2, nil]];
[self.window setRootViewController:tbc];
[self.window makeKeyAndVisible];
return YES;
}
I am trying to navigate from one view to another on touch of a button using iOS 5.0.
The code I am using
- (IBAction)Actionlogin:(id)sender {
NSLog(#" login button has been pressed");
NSLog(#"In init");
test_details *aSecondPageController=[[test_details alloc]initWithNibName:#"test_details" bundle:nil];
[self.navigationController pushViewController:aSecondPageController animated:NO];
}
I have two xib files test_details_iPhone.xib and test_details_iPad.xib
Inside my testdetails.m
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
NSLog(#"it is coming here in second view");
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
NSLog(#"it has been returned ");
return self;
}
LOGs
2013-04-25 11:06:17.191 app_gototest[3067:207] login button has been pressed

2013-04-25 11:06:17.196 app_gototest[3067:207] it has been returned
The view is not getting loaded onto the view. I suppose I am missing something.

navigationController = [[UINavigationController alloc] initWithRootViewController:_viewController];
}
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
return YES;
}
You code looks OK, so it must be that self.navigationController is nil. . . Have you set up a navigation controller?
For your code to work, your current UIViewController needs to be contained within a UINavigationController. . . you can set up the UINavigationController as the root view controller in your application delegate as follows:
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UINavigationController* navigationController;
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil];
navigationController = [UINavigationController alloc] initWithRootViewController:viewController];
} else {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil];
navigationController = [UINavigationController alloc] initWithRootViewController:viewController];
}
self.window.rootViewController = navigationController;
[self.window makeKeyAndVisible];
return YES;
}
NB: You could clean the above code up a little, but you get the picture, which is that you have to set the root view controller to be a navigation controller, like this:
self.window.rootViewController = navigationController;
You could also make a custom root view controller if you like, but the above will let you achieve what you're trying to do - UINavigationController will be used as the navigation system throughout your app.
Your navigation controller is nil. So replace your didFinishLaunchingWithOptions method with
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil];
} else {
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil];
}
UINavigationController *navcontroller = navigationController = [UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = navcontroller;
[self.window makeKeyAndVisible];
return YES;
}
Now you have a navigation controller so the call to push method on the self.navigationController should push the second controller.
Please try
- (IBAction)Actionlogin:(id)sender {
NSLog(#" login button has been pressed");
NSLog(#"In init");
test_details *aSecondPageController=[[test_details alloc]initWithNibName:#"test_details_iPhone" bunndle:nil];
[self.navigationController pushViewController:aSecondPageController animated:NO];
}
// test_details_iPhone.xib and test_details_iPad.xib
//Change initWithNibName#"test_details" with test_details_iPhone or test_details_iPad
I'm developing an iOS 4 application with latest SDK and XCode 4.2.
I'm using an UINavigationController and I don't want to show Navigation Bar. To do that, I use this code on AppDelegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil] autorelease];
}
else
{
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil] autorelease];
}
navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
navController.navigationBar.hidden = YES;
self.window.rootViewController = navController;
[self.window makeKeyAndVisible];
return YES;
}
But, this line, navController.navigationBar.hidden = YES; doesn't work. I don't see navigation bar on first view controller, but I see it on others views.
Any clue?
I have achieved this doing the following:
Setting navController.NavigationBar.hidden = YES; in AppDelegate, after alloc it.
Setting [navController setNavigationBarHidden:YES animated:YES]; on viewWillAppear: on every viewController that I pust to navController.
try
[navController setNavigationBarHidden:YES animated:NO]
The doc is here.
I think that the navigationBar has to be set hidden on the view, not on the controller.
Here is the layout of my app.
ApplicationName
LoginViewController.h
LoginViewController.m
LoginView.xib
AppDelegate.h
AppDelegate.m
ViewController.h
ViewController.m
ViewController_iPhone.xib
ViewController_iPad.xib
Currently in my AppDelegate.m I have:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
LoginViewController *_loginViewController = [[LoginViewController alloc] initWithNibName:#"LoginView" bundle:[NSBundle mainBundle]];
self.loginViewController = _loginViewController;
[_loginViewController release];
[_window addSubview:[loginViewController view]];
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPhone" bundle:nil] autorelease];
} else {
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController_iPad" bundle:nil] autorelease];
}
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
My LoginView.xib has it's File's Owner defined as LoginViewController.
I was at first getting an error stating: reason: '-[UITableViewController loadView] loaded the "LoginView" nib but didn't get a UITableView.'"
I changed UITableViewController to UIViewController and I was able to run the app without an error. The only problem now is that my LoginViewController does not load. I see the blank grey ViewController_iPad.xib loading.
What am I missing here?
I can post up any other code that would be useful.
Thanks in advance!
You should be setting your window's root view controller to self.loginViewController.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.loginViewController = [[LoginViewController alloc] initWithNibName:#"LoginView" bundle:[NSBundle mainBundle]];
[self.loginViewController release];
self.window.rootViewController = self.loginViewController;
[self.window makeKeyAndVisible];
return YES;
}
