I am using Two storyboard one Main and another Dashboard.
After successfull response, I am loading LGSideMenu
Issue is DashboardViewController ViewDidLoad is calling 3 times.
-(void)loadDashboardController{
dispatch_async(dispatch_get_main_queue(), ^{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Dashboard" bundle:nil];
UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:#"NavigationController"];
DashboardViewController *mainViewController = [storyboard instantiateInitialViewController];
mainViewController.rootViewController = navigationController;
[mainViewController setupWithPresentationStyle:LGSideMenuPresentationStyleSlideAbove type:0];
UIWindow *window = [UIApplication sharedApplication].delegate.window;
window.rootViewController = mainViewController;
[UIView transitionWithView:window
duration:0.3
options:UIViewAnimationOptionTransitionCrossDissolve
animations:nil
completion:nil];
});
}
Is any one face this kind of issue?
you should set rootviewcontroller only once on window of your application. that's it. other view controller should be pushed on it or you should set as viewocontrollers of your navigation controller. so only set,
window.rootViewController = mainViewController;
//or
window.rootViewController = navigationcontroller;

I have following code to present a UIViewController (named A) with UINavigationController.
I have kept navigation bar hidden as I do not want it on A by using following code
[self.navigationController.navigationBar setHidden:YES];
but when I push UIViewController named B I want the navigation bar to be displayed but it's not working even If set
self.navigationController?.setNavigationBarHidden(false, animated: false)
on UIViewController B. Can someone help me in this?
Here is the code to present UIViewController A
AppDelegate* delegate = [AppDelegate applicationDelegate];
UIStoryboard *story = [UIStoryboard storyboardWithName:STORYBOARD_MAIN bundle:nil];
SelectionViewController *tutorial = [story instantiateViewControllerWithIdentifier:#"SelectionViewController"];
tutorial.providesPresentationContextTransitionStyle = YES;
tutorial.definesPresentationContext = YES;
[tutorial setModalPresentationStyle:UIModalPresentationOverCurrentContext];
tutorial.delegate = self;
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:tutorial];
navController.modalPresentationStyle = UIModalPresentationFullScreen;
[navController.navigationBar setHidden:YES];
navController.providesPresentationContextTransitionStyle = YES;
navController.definesPresentationContext = YES;
[navController setModalPresentationStyle:UIModalPresentationOverCurrentContext];
[delegate.tabBarController presentViewController:navController animated:YES completion:NULL];
Here is the code to push UIViewController B
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"AppDetail" bundle:nil];
DetailViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"DetailViewController"];
[self.navigationController pushViewController:vc animated:YES];
[[self navigationController] setNavigationBarHidden:NO];
Additional information
UIViewController A is in different storyboard and B is in different
A's code is written in OBJ-C and B's code is in swift.
I have used UISplitViewController on Storyboard, i have set UINavigationController both for master and detail viewcontroller. Master ViewController is loaded, but Detail ViewController does not load.
I could not figure out what might be wrong?
Could you please help me?
My code on AppDelegate is as follows;
if([Utils isIpad])
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPad" bundle:[NSBundle mainBundle]];
UISplitViewController *splitViewController = [storyboard instantiateViewControllerWithIdentifier:#"splitViewController"];
//UISplitViewController *splitViewController = (UISplitViewController *)self.window.rootViewController;
UINavigationController *navigationController = [storyboard instantiateViewControllerWithIdentifier:#"navigationViewControllerMaster"];
splitViewController.delegate = (id)navigationController.topViewController;
[self.window setRootViewController:navigationController];
}
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];
I have this code that works so that once i press a button the view changes in my storyboard:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
ViewController *viewController = (ViewController *)[storyboard instantiateViewControllerWithIdentifier:#"view1"];
[self presentViewController:viewController animated:YES completion:nil];
This code work but when i use it again to change back to my original view using:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
ViewController *viewController = (ViewController *)[storyboard instantiateViewControllerWithIdentifier:#"view2"];
[self presentViewController:viewController animated:YES completion:nil];
It does not work and i receive this error:
Warning: Attempt to present <UIViewController: 0x863ad30> on <UITabBarController: 0x86309b0> whose view is not in the window hierarchy!
The identifies are set and i am not the functions in my viewdidload so i do not know how to fix this.
Can anybody help?
Try this,
First Method
-(IBAction)signin:(id)sender
{
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *vc = [sb instantiateViewControllerWithIdentifier:#"viewController"];
[[[[UIApplication sharedApplication] delegate] window] setRootViewController:vc];
}
Second method (to return back to the previous view)
- (IBAction)signout:(id)sender
{
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *vc = [sb instantiateViewControllerWithIdentifier:#"parentViewController"];
[[[[UIApplication sharedApplication] delegate] window] setRootViewController:vc];
}
This might happen if you call the method before calling makeKeyAndVisible, so move the calling after that.
If not try the hack below:
[[[[[UIApplication sharedApplication] delegate] window] rootViewController] presentViewController:viewController animated:YES completion:nil];
The error message says all: you have to add the view controller's view to the window before presenting the view controller:
UIWindow* keyWindow= [[UIApplication sharedApplication] keyWindow];
[keyWindow addSubview: viewController.view];
[self presentViewController:viewController animated:YES completion:nil];
First View Controller
I'm using a UIStoryBoard to allow the FirstViewController to add the view of second ViewController as a subview. On removing the sub view the
- (IBAction) btnMoveTo:(id)sender
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"Second"];
vc.view.backgroundColor = [UIColor clearColor];
self.modalPresentationStyle = UIModalPresentationCurrentContext;
[self presentModalViewController:vc animated:NO];
}
SecondViewController.m
-(void)viewDidLoad{
self.view.opaque = YES;
self.view.backgroundColor = [UIColor clearColor];
}
- (IBAction) withDraw:(id)sender{
[self.view removeWithZoomOutAnimation:2 option:nil];
}
When I access the withDraw Function, the view of the SecondViewController is removed and firstViewController is back. However when I use the button to access the - (IBAction) btnMoveTo:(id)sender function. It doesn't work. Nothing really happens. Any suggestions or help would be greatly appreciated.
Maybe you can try declare the *vc like this:
UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"Second"];
It worked
- (IBAction) withDraw:(id)sender{
[self.view removeWithZoomOViewControllerutAnimation:2 option:nil];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"First"];
vc.view.backgroundColor = [UIColor clearColor];
self.modalPresentationStyle = UIModalPresentationCurrentContext;
[self presentModalViewController:vc animated:NO];
}
I added another instance of the firstViewController by pointing to its identifier. So it brings back FirstViewController to the top.
