I'm trying to use instantiateViewControllerWithIdentifier in the app delegate to show a view controller but for some reason the navigation bar and tab bar isn't show up. I'm not sure what I'm doing wrong - Thanks
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UINavigationController *view = (UINavigationController *)[sb instantiateViewControllerWithIdentifier:#"ShopViewController"];
self.window.rootViewController = view;
Is ShopViewController a UINavigation controller or is it just a view controller. It sounds like you are declaring the view controller as uinavigationcontroller.
Instead you should either drop a navigation controller on the storyboard and then give that an identifier OR you could just create a navigation controller in the app delegate.
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
ShopViewController *showViewController = (ShopViewController *)[sb instantiateViewControllerWithIdentifier:#"ShopViewController"];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:shopViewController];
self.window.rootViewController = nav;

test1 is the first view in the tarbarcontorller..
after I call presentViewController tab bar is missing
How can i solve it??
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
TestTableViewController *TestTableViewController = [storyboard instantiateViewControllerWithIdentifier:#"test1"];
TestTableViewController.memberid = memberid;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:TestTableViewController];
[self.navigationController presentViewController:navigationController animated:YES completion:nil];
You should present your TabBarController, and not the first view of your tab bar controller. It will display the first view in your tab bar controller properly.
After a successful sign up, I want users to go through a process where they provide photo etc. Similar code to that below worked to load the login page but code below is not working to load a separate view controller in storyboard "newuser".
Would appreciate any suggestions on how to fix.
- (void)presentNewUserInterface
{
UIViewController* rootController = [[UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:#"newuser"];
UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
self.window.rootViewController = navigation;
}
Instead of:
- (void)presentNewUserInterface
{
UIViewController* rootController = [[UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:#"newuser"];
UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
self.window.rootViewController = navigation;
}
Try:
- (void)presentNewUserInterface
{
UIViewController* rootController = [[UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:#"newuser"];
UINavigationController* navigation = [[UINavigationController alloc] initWithRootViewController:rootController];
[self presentViewController:navigation animated:YES completion:nil];
}
You aren't presenting your new navigation controller in your example. Is there a particular reason why you would be trying to replace your rootViewController? That shouldn't be needed. My example should be sufficient for displaying your next flow in the user sign up process.
Two variants:
Replace window.rootViewController with your next view
controller. Do it on AppDelegate class.
Present new view controller
from current root view controller. Do it in your sign up view
controller.
The lack of the first method is no transaction animation. So second method is preferable.
In my AppDelegates 'didFinishLaunchingWithOptions' function, I have this code in there:
if(loggedIn != nil)
{
MainViewController *mvc = [self.window.rootViewController.storyboard instantiateViewControllerWithIdentifier:#"MainView"];
[self.window setRootViewController:mvc];
}
Second Attempt which didn't work:
if(loggedIn != nil)
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
MainViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"MainView"];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
[self.window setRootViewController:nav];
}
The problem is that when the MainViewController loads, the NavigationHeader is missing. I've tried various methods online and instantiations that basically do the same thing to no avail. I have also tried created a whole new navigationController and adding my view to it, however, that fails as well.
Your setting MainViewController as your root, if this is not a navigation controller, there will be no header when it opens.
Instead create a UINavigationController, set MainViewController as its root and then set the navigation controller as the window root.
e.g.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"storyboardName" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"home"];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
[self.window setRootViewController:nav];
or if you have the navigation controller inside the storyboard then instantiate that. Most likely the initial view controller.
e.g.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"storyboardName" bundle:nil];
[self.window setRootViewController::[storyboard instantiateInitialViewController]];
not sure if it will be the initial viewController or not, that requires more info of your setup to know.
I want to add a navigation view controller prior to the user getting to the splitview controller. I have tried a few ways of changing the root controller when I want to go from navigation controller to splitview controller but I don't seem to be setting the delegate the right way when I do this.
Code WITHOUT nav view (works perfectly):
AppDelegate
UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [splitViewController.viewControllers lastObject];
splitViewController.delegate = (id)navigationController.topViewController;
UINavigationController *masterNavigationController = splitViewController.viewControllers[0];
MasterViewController *controller = (MasterViewController *)masterNavigationController.topViewController;
controller.managedObjectContext = self.managedObjectContext;
Code with nav view prior to SplitView
AppDelegate
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController* rootController = [[UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:#"dummy"];
self.window.rootViewController = rootController;
[self.window makeKeyAndVisible];
DummyViewController
AppDelegate *appDelegateTemp = [[UIApplication sharedApplication]delegate];
appDelegateTemp.window.rootViewController = [[UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]] instantiateInitialViewController];
This takes me from the DummyViewController that I launched into, to the splitview controller which is the initial view controller in Storyboard. Which is fine however, when I do it this way none of the delegates get called. This is probably because when changing root controllers, it is not setting the delegates properly. How can I get this to work the right way?
It seems the only really non-hacking way to do it is to present a modal view over the split view in the detail view controller
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
DummyViewController *dummy = (DummyViewController *)[storyboard instantiateViewControllerWithIdentifier:#"dummy"];
[self presentViewController:dummy animated:NO completion:nil];
By setting animation to NO, the user does not see the split view loaded behind it.
I'm developing push notification on my app. I want that when people tap on push message, app open a specific controller;
If I do that with:
storyBoardName = #"MyStoryboardName";
UIStoryboard* storyBoard = [UIStoryboard storyboardWithName:storyBoardName bundle:nil];
MainWebController* MainWeb = [storyBoard instantiateViewControllerWithIdentifier:#"MainWeb"];
MainWeb.urlToLoad = URL_TO_LOAD;
self.window.rootViewController = MainWeb;
[self.window makeKeyAndVisible];
works, I can see MainWeb when i tap on push massage but the controller view cover all the screen: tab bar and navigation bar are hided!
I know that rootviewcontroller is a uitabbar:
NSLog(#"Controller: %#",self.window.rootViewController.debugDescription);
Solved with:
UITabBarController *tabController = (UITabBarController *)self.window.rootViewController;
tabController.selectedIndex = 0;
UINavigationController *navigationController = (UINavigationController *)tabController.selectedViewController;
[navigationController pushViewController:MainWeb animated:YES];
You are replacing the rootViewController by setting it to be a MainWebController. Is this the initial UIViewController in your Storyboard?
From your issue it would seem that the initial UIViewConroller is a TabViewController and what you actually want is to setup a UIViewController inside this.
