I am trying to create window programmatically in App delegate, but status bar hides. In info.plist it is is not set to YES. The app is perfectly working in this way, but I need to show status bar too.
I have window and navigationController property in AppDelegate.h
here is my didFinishLaunch
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//even when I used customized CGRect and used it initWithFrame, there is no status bar
self.navigationController = [[IEENavigationController alloc] init];
XYZViewController *homeViewController = [[XYZViewController alloc] initWithNibName:#"XYZViewController" bundle:nil];
[navigationController pushViewController:homeViewController animated:YES];
self.window.rootViewController = self.navigationController;
[window addSubview:navigationController.view];
[self.window makeKeyAndVisible];
return YES;
Thank you in advance
You could add this in the info.plist:
UIViewControllerBasedStatusBarAppearance - YES
then add this method in the view controllers you want to hide the status bar.
-(BOOL)prefersStatusBarHidden { return YES; }

This is how I launched by main controller in my iOS app.
UIViewController *rootController = [[RootViewController alloc] init];
navigationController = [[UINavigationController alloc] initWithRootViewController:rootController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
[self.window makeKeyAndVisible];
return YES;
With this I am getting a blank bar at the top.
I want to use a navigation controller to control the flow of screens that users are able to reach by pressing back but I don't want a navigation bar. How can I change my code to get what I want?
You can use this code right after you declare navigationController = ... in the code sample you provided:
[navigationController setNavigationBarHidden:true];
And then whenever you need to go "back," your app would run this code from within the current view controller:
[self.navigationController popViewControllerAnimated:true];
I am trying to make a tableview with two views, the tableview controller and the otherView controller. The tableview needs a navigation controller to get to a third view when a cell is clicked. I tried using the code below in my AppDelegate.m but it just creates the tableview with the navigation controller. Any suggestions on how I should edit this to get the tabview working as well? Thanks!
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
AJBTableViewController *masterViewController = [[AJBTableViewController alloc] initWithNibName:nil bundle:nil];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:masterViewController];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
_mainTabBar.viewControllers = [NSArray arrayWithObjects:_navigationController, otherViewController, nil];
[_window addSubview:_mainTabBar.view];
return YES;
}
The tab bar controller should be the root view controller of the app, not the navigation controller of the first tab bar item.
_mainTabBar.viewControllers = [NSArray arrayWithObjects:_navigationController, otherViewController, nil];
[_window addSubview:_mainTabBar.view];
Instead this code, you try below code:
UITabBarController *tbC = [[UITabBarController alloc]init];
tbC.viewControllers = [NSArray arrayWithObjects:_navigationController,otherViewController, nil];
self.window.rootViewController = tbC;
and delete
self.window.rootViewController = self.navigationController;
Sorry for the stupid error, I never allocated an instance of the tabbar controller, Mundi is right, making the rootviewcontroller the tabbarcontroller is the way to go.
My requirement is that UITabBarController is the rootviewcontroller and on very first time of app launch I want to show login procedure which is inside UINavCon, and I am displaying it through presentViewController.
I dont want the UITabBarController visible for first time and dont want to how login UINavCon popping as modal.
I want to make user experience that if app starts for first time login UINavCon should be visible. So here is my code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window makeKeyAndVisible];//is it correct to call it here?
LoginVC *loginObj = [[LoginVC alloc]init];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:cellPhoneNumber];
self.tabBarController = [[UITabBarController alloc]init];
self.window.rootViewController = self.tabBarController;
[self.tabBarController presentViewController:self.navigationController animated:NO completion:^{}];
return YES;
}
I am calling [self.window makeKeyAndVisible]; on second line right after uiwindow alloc init. Is it correct do this or I can experience problems like viewcontroller not receiving events or orientations notifications?
you can call it whenever you want. Calling it affects the window's z-index and screen property.
it doesnt depend on any specific content being set.
You haven't mentioned that whether you got the code working or not by using your implementation. Anyways I have done similar kind of implementation recently where we need to present login controller and then tabBarController after logging in, so just sharing my implementation.
Create your login controller and present it in didFinishLaunching method.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
LoginController *loginCObj= [[[MainScreenController alloc]init]autorelease];
UINavigationController *navigationControllerObj = [[[UINavigationController alloc]initWithRootViewController:loginObj]autorelease];
self.window.rootViewController = navigationControllerObj;
[self.window makeKeyAndVisible];
After that on succesful login in your login view controller, call an appDelegate public method
In login controller
AppDelegate *appDel = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDel applicationLoggedInSuccesfully];
In your appDelegate file, add a method like this:
-(void)applicationLoggedInSuccesfully{
UINavigationController *nv1 = [[[UINavigationController alloc] initWithNibName:nil bundle:nil]autorelease];
TabController1 *v1 = [[[TabController1 alloc] initWithNibName:nil bundle:nil]autorelease];
[nv1 pushViewController:v1 animated:NO];
UITabBarController *tabController = [[[UITabBarController alloc] init]autorelease];
tabController.viewControllers = #[nv1];
tabController.delegate = self;
self.window.rootViewController = tabController;
[self.window makeKeyAndVisible];
}
Hope it will help you.
I am using storyboards and this code but nothing is appearing in my current viewConntroller but is in my first viewConntroller. Can anybody eli me set the keywindow to the current view i am on?
Here is the code i am using to show my UINavigationBar
[[[UIApplication sharedApplication] keyWindow] addSubview:bar];
Thanks in advance
you dont set the Viewcontroller to a Window
you need to do something like this:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
this is how you add a uinavigationcontroller:
Add a UINavigationBar to a UITableViewController without a UINavigationController
if you want to present a new view controller
you simply use presentModalViewcontroller:
UIViewController *vc = [[UIViewController alloc] init];
[self.navigationcontroller vc animated:YES];
// I have written it all down just check the case and use it
I have a tab bar application in Xcode 4.3 and I'm trying to insert a login screen before the tabbar is shown. The app works OK if presentModalViewController has animated:YESbut if it is without animation the view is not showing.
#synthesize window = _window;
#synthesize tabBarController = _tabBarController;
- (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];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
self.window.rootViewController = self.tabBarController;
LogInViewController *logViewController = [[LogInViewController alloc] initWithNibName:#"LogInViewController" bundle:nil];
[self.window addSubview:_tabBarController.view];
[self.tabBarController presentModalViewController:logViewController animated:YES];
//This wont work
//[self.tabBarController presentModalViewController:logViewController animated:NO];
[self.window makeKeyAndVisible];
return YES;
}
-(void)loginDone{
NSLog(#"back to the app delegate");
[self.tabBarController dismissModalViewControllerAnimated:YES];
}
Is this the right way to do it?
Why wont the code work with animated:NO ?
I also get this on output Unbalanced calls to begin/end appearance transitions for <UITabBarController: 0x689d350>.
First of all, move [self.window makeKeyAndVisible]; before your view controller setup.
Additionally, you should be presenting the modal view controller within the viewWillAppear: method of the view controller that will be visible first, to make sure your apps view hierarchy has been fully initialized before presenting your login screen.
Don't do this:
[self.window addSubview:_tabBarController.view];
Do this:
self.window.rootViewController = _tabBarController;
This will put the tabBarController on the screen. But that's not exactly what you want... My advise is:
1) Start by putting the logViewController has the rootViewController as I showed you above.
2) Once you got what you want (login is successful) just tell the AppDelegate to switch the rootViewController. This can be done in with delegation or notifications.
Also, as Toastor indirectly pointed out, you should start the presentViewController from the UIViewController who actually initiates it (and not from the AppDelegate).
