I am developing iOS app in which i have side menu with TabBar,
I have settled My sidemenu container viewController as IntitalViewController of my app.
Here is my code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]];
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:#"navigationController"];
UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"leftSideMenuViewController"];
[container setLeftMenuViewController:leftSideMenuViewController];
[container setCenterViewController:navigationController];
return YES;
}
Here is the Design of my Storybaord:
When i run my app i see a black screen with no error
Where i am making mistake, please help
Thanks in adavnnce !!
Give try to this (after seeing your code):
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]];
self.window.rootViewController=[[MFSideMenuContainerViewController alloc]init];
// Override point for customization after application launch.
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UITabBarController *tabController = [storyboard instantiateViewControllerWithIdentifier:#"tabBarController"];
UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"leftSideMenuViewController"];
[container setLeftMenuViewController:leftSideMenuViewController];
[container setCenterViewController:tabController];
[self.window makeKeyAndVisible];
return YES;
}
Also give the respective id's to view controllers in storyboard ( for tabBar, navigation)
and don't forget to give root view controller for navigation
controller.

Does anyone know how to do this in the ExtensionDelegate? Here's how I did it in the AppDelegate for iPhone
self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStory" bundle:nil];
UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:#"2ndScreen"];
self.window.rootViewController = viewController;
[self.window makeKeyAndVisible];
My app is mainly constructed without storyboards.
However, I have created just one for the registration of users.
This storyboard consists of a navigation controller containing 2 views controllers.
The first one is called "FirstVC", and the one "SecondVC" (this one would not be used for my question).
I am trying to push it in the AppDelegate.m file (trying various ways, see below) but my screen is always black.
attempt 1
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"FirstRegistration" bundle:nil];
FirstVC *fvc = [sb instantiateViewControllerWithIdentifier:#"FirstVC"];
UINavigationController *navController =(UINavigationController *)self.window.rootViewController;
[navController pushViewController:fvc animated:YES];
return YES;
}
attempt 2
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"FirstRegistration" bundle:nil];
FirstVC *fvc = [sb instantiateViewControllerWithIdentifier:#"FirstVC"];
self.window.rootViewController = fvc;
return YES;
}
Note : I've set the FirstVC scene to FirstVC in the identifier Custom Class section and also set the storyboard ID to FirstVC. However I have not touched to the NavigationController scene, should I just set the custom class to UINavigationController ?
can you try adding this line
[self.window makeKeyAndVisible];
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"FirstRegistration" bundle:nil];
FirstVC *fvc = [sb instantiateViewControllerWithIdentifier:#"FirstVC"];
self.window.rootViewController = fvc;
[self.window makeKeyAndVisible]; //**Add this**
return YES;
}
My MainViewController loads another view modally.
#implementation MainViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *uiViewController = [storyboard instantiateViewControllerWithIdentifier:#"splashViewController"];
[uiViewController setModalPresentationStyle:UIModalPresentationCustom];
[uiViewController setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentViewController:uiViewController animated:YES completion:nil];
}
When I load the MainViewController directly from the AppDelegate, the modal view is loaded.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIViewController *rootController = [[RootViewController alloc] init];
navigationController = [[UINavigationController alloc] initWithRootViewController:rootController];
[navigationController setNavigationBarHidden:true];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
[self.window makeKeyAndVisible];
return YES;
}
If I load the MainViewController as a child controller of another controller, then the modal view fails to load.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.drawerViewController.leftViewController = self.leftDrawerViewController;
self.drawerViewController.centerViewController = self.mainViewController;
self.drawerViewController.animator = self.drawerAnimator;
UIViewController *rootController = self.drawerViewController;
navigationController = [[UINavigationController alloc] initWithRootViewController:rootController];
[navigationController setNavigationBarHidden:true];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
[self.window makeKeyAndVisible];
return YES;
}
The main view still loads. It's only that the modal view is not created.
What's causing the problem and how can I resolve this?
You should not present another view controller from viewDidLoad method ,
by that time , current view is NOT finished with its view-hieararchy changes ,
You can present new viewcontroller after viewDidAppear is called ,
so you can move that code to viewDidAppear
I need to show a ViewController from the appDelegate every time the app comes from the background in the applicationDidEnterBackground method.
The *securityCheck prompts the user for a passcode very much like the normal passcode in iOS. Once the passcode is validated I call dimissViewControllerAnimated inside the securityCheck and I am left with my blank UINavigationController, since the view was presented from the appDelegate I have no record of who presented the view, so I can't popToRootViewController.
My question is how can I properly dismiss the SecurityCheckViewController so that it shows the ViewController which the user was on before the app entered the background.
Here's my code:
This method is called inside AppDelegate.m
- (void)securityCheck {
SecurityCheckViewController *securityCheck = [[SecurityCheckViewController alloc] init];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:securityCheck];
[securityCheck presentedByAppDelegate:YES];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window setRootViewController:navigationController];
[self.window makeKeyAndVisible];
}
Then inside the SecurityCheckViewController.m I have
- (void)unlockWasSuccessfulForPadLockScreenViewController:(ABPadLockScreenViewController *)padLockScreenViewController {
[self.appDelegate securityCheckDone];
[padLockScreenViewController dismissViewControllerAnimated:YES completion:nil];
NSLog(#"Sucsessfull Unlock");I'm
}
Present
- (void)securityCheck {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
SecurityCheckViewController *securityCheck = [storyboard instantiateViewControllerWithIdentifier:#"securityCheckView"];
[self.window.rootViewController presentViewController:securityCheck animated:NO completion:nil];
}
Dismiss
[self dismissViewControllerAnimated:YES completion:nil];
You can call this from application:didFinishLaunchingWithOptions
NOTE: All the storyBoard "initialViewControllers" tick box on the property inspector is turned off
UIStoryboard *storyboard =
[UIStoryboard storyboardWithName:#"Registration" bundle:nil];
RegisterViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"RegisterViewController"];
//this is key else you get a black screen
self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];
self.window.rootViewController = vc;
[self.window makeKeyAndVisible];
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;
}
