My app consists of a navigation controller and view controllers. Some parts of my UI is done on storyboard and some are initiated from code (in viewDidLoad). My goal is to load childViewController X (consists of a back button, nag bar, label and table) when the app is launched from a push notification "properly" through this method in appDelegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
This might be a simple question to you guys but I've asked several questions the pass few days (you can look at my questions history). After trying several methods, my app either:
crashes
loads without navigation bar
loads with navigation bar but no label (back button does not work)
loads with navigation bar but with black screen underneath
Only the tableView is dragged onto storyboard. The navigation bar is inferred but I have code that dictates its back button and title. The rest is all done through code in the .m file.
I know people have asked this question before but none of the methods worked. How can I load this childViewController properly through a push notification?
My code so far:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (dictionary != nil)
{
UIStoryboard *mainstoryboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UIViewController* firstVC = [mainstoryboard instantiateViewControllerWithIdentifier:#"NotificationsViewController"];
[self.window.rootViewController addChildViewController:firstVC];
[(UINavigationController *)self.window.rootViewController pushViewController:firstVC animated:NO];
self.window.rootViewController.childViewControllers);
}}
Error Code:
'-[SWRevealViewController pushViewController:animated:]: unrecognized selector sent to instance 0x14575f20'
SWRevealViewController is my library for my sidebar menu view controller.
I've also tried this method:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UIViewController *initViewController = [storyboard instantiateViewControllerWithIdentifier:#"NotificationsViewController"];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = initViewController;
[self.window makeKeyAndVisible];
This loads the correct viewController but without a navigation bar.
It looks like you have your rootViewController set to a custom controller of type SWRevealViewController. If you want to call pushViewController:animated: on rootViewController, it must be a UINavigation controller. Currently you are calling it on a controller that does not respond to that message.
In your Storyboard make sure you drag a UINavigationController onto the canvas and move the root-view-controller arrow in InterfaceBuilder to point to it. Then load whatever ViewController you want into the navigationController. (i.e. your code at the top of your question should work).

I am making a messaging app on ios that will have multiple folders for different types of messages. I will be using a navigation controller structure and would like the root view to be where the user can choose which folder to view. However, when I first segue to the navigation controller I would like the inbox folder view to display directly (ie. bypass the root view). Apples mail app has a similar structure (launches inbox when it opens). how can I do this?
It really depends on how the relationship is between the first view controller and the second view controller. If you want to do something like this, why don't you put your second view controller as the root controller of the UINavigationController.
Anyway, if you still want to do it the way you describe, you can just direct to the second view controller using the viewDidLoad method from your root view controller. But, it will make the UI looks clumsy.
try to use this code :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
UIStoryboard *board = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
ViewController *controller1 = [board instantiateViewControllerWithIdentifier:#"firstView"];
UINavigationController *navController = [[UINavigationController alloc]initWithRootViewController:controller1];
SecondViewController *secondView = [board instantiateViewControllerWithIdentifier:#"secondView"];
[controller1 addChildViewController:secondView];
[self.window setRootViewController:navController];
return YES;
}
Hope this will help you.
Write this code in didFinishLaunchingWithOptions of AppDelegate.m
UIStoryboard *MainStoryboard = [UIStoryboard storyboardWithName:#"Main"
bundle: nil];
UINavigationController *controller = (UINavigationController*)[MainStoryboard
instantiateViewControllerWithIdentifier: #"YourStoryBoardID"];
NeededViewController *need=[MainStoryboard instantiateViewControllerWithIdentifier:#"YourStoryboardID"];
[controller setViewControllers:[NSArray arrayWithObject:need] animated:YES];
self.window.rootViewController=controller;
I'm following the advice of this question in order to define my initial view controller at runtime, instead of always being the same based off of the Storyboard property.
This is my didFinishLaunching method:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UINavigationController *compactNavigationController = [mainStoryboard instantiateViewControllerWithIdentifier:#"CompactNavigationController"];
self.window.rootViewController = compactNavigationController;
[self.window makeKeyAndVisible];
CompactPostsViewController *controller = (CompactPostsViewController *)compactNavigationController.topViewController;
controller.managedObjectContext = self.managedObjectContext;
return YES;
}
And I've unchecked "Is Initial View Controller" in my Storyboard, and I've removed "Main" from the default Storyboard in my app's info.
But when I launch the app I get a completely black screen. What am I doing wrong?
Your window is nil because you never created it. You need to add this line,
self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];
The window is created for you when you have the "Main storyboard base name" entry in your info.plist, but if you remove that, then you have to create the window yourself.
check your linkings in your storyboard(by right click on the tableview controller).This happens mostly when you not linked your tableview controller properly.
Hi in storyboard i have added a new view controller object inside the view controller i have a small registration from with only two fields example like name and phone number. In that when user open the application i want display only the newly added UIview.
But the problem is uiview is showing with the storyboard please tell me how to display only the uiview. Is that possible to do ? possible means please tell how to make it done. I'm navigating the view from my app-delegate.
App delegate code.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *mainstoryboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
buttonpoliticalViewController *ringingVC = [mainstoryboard instantiateViewControllerWithIdentifier:#"Upcv"];
[self.window setRootViewController: ringingVC];
return YES;
}
In above code i have used the storyboard id to view the view controller please tell how to display only uiview.
Thanks.

You had some problem in your code:
You need to have a UINavigationController in order to have a navigation bar and manage the push/pop actions, so your window root controller should be a UINavigationController.
If you need to initialize a UINavigationController the best and simple way is to initialize it with a root controller directly, so leave the push/pop for user actions: an application has always a root controller, so why don't you create it immediately?
The "addChildController" is another thing: it is used to create custom container controller, it means that you have to implement all the business logic manually. I suggest you to use it only if you are experienced enough, since it could be difficult - Cocoa has enough components to leave it for a small set of applications.
You are using a third part controller, the "SWRevealViewController". They should have an example project, you can try to "copy" it and them customize it for your own purpose.
Let me know if your code works well, otherwise post the new error and I'll try to help you
I'm implememting a design based on the TabbedBanner example in the iAdSuite. I have a UINavigationController in the first tab. In that UINavigationController I have a view controller that simply has a button that pushes to another view controller. The pushed view controller is set to Hide Bottom Bar On Push in Interface Builder.
Here is the code where I'm setting up the UITabBarController.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:[[NSBundle mainBundle].infoDictionary objectForKey:#"UIMainStoryboardFile"] bundle:[NSBundle mainBundle]];
_tabBarController = [storyboard instantiateViewControllerWithIdentifier:#"TabBarController"];
_tabBarController.delegate = self;
FirstViewController *firstView = [storyboard instantiateViewControllerWithIdentifier:#"FirstViewController"];
UINavigationController *firstNav = [[UINavigationController alloc] initWithRootViewController:firstView];
_tabBarController.viewControllers = #[[[BannerViewController alloc] initWithContentViewController:firstNav], ];
self.window.rootViewController = _tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
Everything works except the TabBar does not get hidden when I push to the next view controller. I have tried hiding the TabBar using the Interface Builder check box as well as using nextViewController.hidesBottomBarWhenPushed = YES and neither way works.
If I remove the BannerViewController implementation, the TabBar hides exactly as it should.
It seems to me that the BannerViewController is interfering with the UINavigationController being able to hide the TabBar.
Is it possible to use Hides Bottom Bar When Pushed to hide the TabBar in this type of setup?
Thanks
Note: I realize that the code above only has one tab. I removed the other tabs for clarity.
I think this is happening because the BannerViewController itself is just a container viewController and it never actually pushes another view controller. The view controllers are pushed within the container.
