Hi I have a UITabBarController which i want to add on top an overlay containing a registration form.
I've seen several places that the way to go is to use this command:
[[[UIApplication sharedApplication] keyWindow] addSubview:registrationView];
But How can I create registrationView from the storyboard and be able to access it from the UITabBarController?
Note: My registrationView should hide the tabs so i can't put it in one tab.
Hey this will solve you issue
UITabBarController *tabBarController = (UITabBarController *) self.window.rootViewController;
ViewController *RegistrationView = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
[tabBarController presentModalViewController:RegistrationView animated:YES];
[tabBarController.selectedViewController viewDidAppear:true];
do this in - (void)applicationDidBecomeActive:(UIApplication *)application function

I am begin to study iOS and I try to do left navigation with MMDrawerController
my AppDelegate didFinishLaunchingWithOptions code is:
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *leftView = [mainStoryboard instantiateViewControllerWithIdentifier:#"LeftViewController"];
UINavigationController *leftNav = [[UINavigationController alloc]initWithRootViewController:leftView];
UIViewController *centerView = [mainStoryboard instantiateViewControllerWithIdentifier:#"CenterViewController"];
UINavigationController *centerNav = [[UINavigationController alloc]initWithRootViewController:centerView ];
self.drawerController = [[MMDrawerController alloc] initWithCenterViewController:centerNav leftDrawerViewController:leftNav];
self.drawerController.openDrawerGestureModeMask = MMOpenDrawerGestureModePanningCenterView;
self.drawerController.closeDrawerGestureModeMask = MMCloseDrawerGestureModePanningCenterView;
self.window.rootViewController = self.drawerController;
[self.window makeKeyAndVisible];
// Override point for customization after application launch.
return YES;
}
So it's work fine, but I have LoginViewController on my app, and if user has no saved token on NSUserDefaults, I must show LogionViewController.
Of course side menu must be hidden on LoginViewController.
I Tried to switch to LoginViewController inside my CenterViewController:
- (void)viewDidLoad {
[super viewDidLoad];
LoginViewController * vc = [[LoginViewController alloc] init];
AppDelegate *app = [[UIApplication sharedApplication] delegate];
[app.drawerController setCenterViewController:vc withCloseAnimation:YES completion:nil];
}
But I have black screen only.
What I do wrong?
Thanks
What you're doing is a bit weird because you are setting the new centerViewController (of type LoginViewController) within the current one (of type CenterViewController), and once that is done the latter one will be deallocated because there are no more references to it. This might somehow be causing the black screen.
One solution would be to have the LoginViewController outside the MMDrawerController, and always present it at the beginning. If there is no token, then quickly (without animation) present the MMDrawerController and the LoginViewController won't even be seen. This way also allows you to easily dismiss back to the login screen if the user logs out.
Another option is to just present your LoginViewController from the CenterViewController modally (or however you like really) using presentViewController:animated:completion:, and then just dismiss it when they log in.
i am beginner iOS dev, I have my app with many controllers.
After login on LoginViewController (LoginViewController has segue relation with NavigationViewController) I do init MMDrawerViewController with this code:
-(void)initSidebarController{
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *leftView = [mainStoryboard instantiateViewControllerWithIdentifier:#"LeftViewController"];
UIViewController *centerView = [mainStoryboard instantiateViewControllerWithIdentifier:#"CenterViewController"];
UINavigationController *leftNav= [[UINavigationController alloc]initWithRootViewController:leftView];
UINavigationController *centerNav= [[UINavigationController alloc]initWithRootViewController:centerView];
appDelegate.drawerController= [[MMDrawerController alloc]initWithCenterViewController:centerNav leftDrawerViewController:leftNav];
appDelegate.drawerController.openDrawerGestureModeMask = MMOpenDrawerGestureModePanningCenterView;
appDelegate.drawerController.closeDrawerGestureModeMask = MMOpenDrawerGestureModePanningCenterView;
appDelegate.window.rootViewController = appDelegate.drawerController;
[appDelegate.window makeKeyAndVisible];
}
Now I want to push DishesViewController on NavigationViewController when user didSelectRowAtIndexPath .
How can I do this correctly ?
Thanks
Go to the storyboard, select dishesViewController and select the identity inspector from the left pane and in the StoryboardID enter "dishesVC" then use this code :
CateringDishesViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"dishesVC"];
[self.navigationController pushViewController: animated:YES]
Please follow below step, I am sure it will work for you.
1) Get top ViewController (Reference link).
2) If your MMDrawerController library configure is proper then you will get MMDrawerController as a top view controller.
3) Then find center UINavigationController
4) By using center navigation controller you can to new view controller into stack.
If you don't able to do it then provide sample source code with us. So we can provide exact solution.
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?
EDIT/UPDATE:
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.
UPDATE2:
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.
Try this:
- (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"];
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
// Navigation already created
if(navigationController) {
[navigationController pushViewController:firstVC animated:NO];
// Navigation not created
} else {
UINavigationViewController *navigationController = [[UINavigationViewController alloc] initWithRootController:firstVC];
[self.window setRootViewController:firstVC];
[self.window makeKeyAndVisible];
}
}
return YES;
}
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
Hi Fellow iOS Developers, I am a newbie developing a project with 5 tab Views and on the first and second tabs I have slide out menus using Container views from example code by Michael Frederick on his GitHub page Project Link: https://github.com/mikefrederick/MFSideMenu. He is using a nib (.xib) files though I am using Storyboard to achieve the same and struck with defining the container and child views. can kindly some one advice how to modify the below code to accommodate in my storyboard.
the original code in the AppDelegate.m is
- (DemoViewController *)demoController {
return [[DemoViewController alloc] initWithNibName:#"DemoViewController" bundle:nil];
}
- (UINavigationController *)navigationController {
return [[UINavigationController alloc]
initWithRootViewController:[self demoController]];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UITabBarController *tabBarController = [[UITabBarController alloc] init];
[tabBarController setViewControllers:[NSArray arrayWithObjects:[self navigationController],
[self navigationController], nil]];
SideMenuViewController *leftSideMenuController = [[SideMenuViewController alloc] init];
SideMenuViewController *rightSideMenuController = [[SideMenuViewController alloc] init];
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
containerWithCenterViewController:tabBarController
leftMenuViewController:leftSideMenuController
rightMenuViewController:rightSideMenuController];
self.window.rootViewController = container;
[self.window makeKeyAndVisible];
return YES;
}
#end
how to modify the code to accommodate the container parent view and child views ?
where should i instantiate the code for the parent and child of the 2nd tab view ? in AppDelegate or the View Controller ?
If any other Details are required leave a comment please. Any Help Will be greatly appreciated. thanks in Advance.
I don't know if you still need this, but i had the exactly same problem today, too. What you need to do is:
remove the both methods over your app Delegate
put this in your app Delegate:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"YOUR_STORYBOARD" bundle:[NSBundle mainBundle]];
MFSideMenuContainerViewController *container = (MFSideMenuContainerViewController *)self.window.rootViewController;
UIViewController *leftSideMenuViewController = [storyboard instantiateViewControllerWithIdentifier:#"THE_IDENTITY_OF_YOUR_SIDEMENU"];
UITabBarController *centerViewController = [storyboard instantiateViewControllerWithIdentifier:#"IDENTITY_OF_YOUR_TABBARCONTROLLER"];
[container setCenterViewController:centerViewController];
[container setLeftMenuViewController:leftSideMenuViewController]; //for the right Side, its the same way...
[container setPanMode:MFSideMenuPanModeNone]; //remove this line, if you need the pan mode
return YES;
In your Storyboard you have to put a ViewController as a subclass from "MFSideMenuContainerViewController". Mark this View as the "Initial View Controller" in the Attribute Inspector. Now use a Segue from your new Initial View Controller and let it "push" to your TabBarController. To avoid a Warning rename the Segue.
After you have done this, you can add a UIBarButtonItem to every View, you like to add the SideMenu. In the Action Method of this UIBarButtomItem you only need to do this:
[self.menuContainerViewController toggleLeftSideMenuCompletion:^{}];
finally make sure you have a UIViewController or a UITableViewController, that is your "SideMenu" and set the right Storyboard ID.
if you are still need help, comment this...
and sorry for my english :)
You can use https://github.com/ozcanakbulut/VoovilSideMenu. It's easy to embed in a tabBarController. It uses Storyboard and Arc.
I have two issues that I don't understand and am hoping that someone can help.
This code doesn't work for taking my existing UINavigationController hierarchy from a split view controller and taking over the screen with it. I just get a dark screen
UINavigationController* myself = self.navigationController;
[myself removeFromParentViewController];
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"QuestionnaireViewController"];
[myself pushViewController:controller animated:YES];
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
app.window.rootViewController = myself;
However, this code does work. Why can I set the rootViewController to a new UINavigationController but not self.navigationController?
UINavigationController *navController = [[UINavigationController alloc] init];
UINavigationController* myself = self.navigationController;
[myself removeFromParentViewController];
navController.viewControllers = myself.viewControllers;
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"QuestionnaireViewController"];
[navController pushViewController:controller animated:YES];
AppDelegate *app = (AppDelegate *)[[UIApplication sharedApplication] delegate];
app.window.rootViewController = navController;
My second issue is in restoring the navigation controller to the splitViewController when the user goes "back". I know from experience that I can assign a new UINavigationController to the detailView, but I cannot assign self.navigationController.
I think the issues are the same issue. For some reason a new UINavigationController is not the same as a UIView's navigationController. Why?
Meddling with UIWindow is not very safe.
Depending on what you are trying to achieve, I can think of 2 rather simple options
a) iOS 5.1+ has an option to show/hide the RootViewController of your split and show with a swipe gesture, and work with that
b) Create your own UIViewController that emulates UISplitViewController, and hide the left part whenever you need to
