Hi there I used this code to move in to new contorller just with code and without segue .
UIStoryboard * mainstoryb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController * vc = [mainstoryb instantiateViewControllerWithIdentifier:#"online_shop"];
[self presentViewController:vc animated:YES completion:nil];
how do I show Navigation bar or title bar on next view ?
You need to present NavigationController as below :
UIViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:ContactUSVCID];
UINavigationController *objNav = [[UINavigationController alloc] initWithRootViewController:vc];
[self presentViewController:objNav animated:YES completion:nil];
if you want navigation bar, then you have to push not present
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
SecondViewController * vc = [storyboard instantiateViewControllerWithIdentifier:#"ViewControllerB"];
/********if dont have navigation bar***********/
UINavigationController *initialNavigationController = (UINavigationController*)[self.storyboard instantiateViewControllerWithIdentifier:#"HomeNavCtrl_id"];
[self presentViewController:initialNavigationController animated:YES completion:nil];
/**********else*************/
[[self navigationController] pushViewController:vc animated:YES];
Embed your ViewController in navigation controller and storyboard id to navigation controller then use this code
UINavigationController *initialNavigationController = (UINavigationController*)[self.storyboard instantiateViewControllerWithIdentifier:#"HomeNavCtrl_id"];
[self presentViewController:initialNavigationController animated:YES completion:nil];
If you present a view controller it will always be presented full screen.
Try this
UIStoryboard * mainstoryb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController * vc = [mainstoryb instantiateViewControllerWithIdentifier:#"online_shop"];
[self presentViewController:navigationController animated:YES completion:nil];

Hi i have two Viewcontroller A and B and i am presenting B Controller from A Controller with Current Context and I pasted my coding below. All i want to push from B controller to C controller, I know that no navigation controller allocated when we present and if i present navigationcontroller with rootviewcontroller i cannot achieve transparent result.
UIStoryboard *story = [UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]];
ChooseAddressVc *sec=[story instantiateViewControllerWithIdentifier:#"ChooseAddressVc"];
sec.myDelegate = self;
sec.modalPresentationStyle = UIModalPresentationOverCurrentContext;
sec.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:sec animated:YES completion:^{
}];
Pushing from Viewcontroller B to C
UIStoryboard*Story=[UIStoryboard storyboardWithName:#"Main2" bundle:nil];
AddNewAddressVc*choose=[Story instantiateViewControllerWithIdentifier:#"AddNewAddressVc"];
[self.navigationController pushViewController:choose animated:YES];
Note:I need to push from B to C controller when i present with current context. FOR BETTER UNDERSTANDING:WE CANNOT ALLOCATE NAVIGATION CONTROLLER AS ROOT VIEWCONTROLLER FOR A WHEN WE NEED TO GET TRANSPARENCY EFFECT
In your case self.navigationController in B view controller is nil. You need to create UINavigationController with B view controller as rootViewController. Present created UINavigationController from A instead presenting B view controller, after this you're able to use self.navigationController in B view controller.
Your code edited:
UIStoryboard *story = [UIStoryboard storyboardWithName:#"Main" bundle:[NSBundle mainBundle]];
ChooseAddressVc *sec=[story instantiateViewControllerWithIdentifier:#"ChooseAddressVc"];
sec.myDelegate = self;
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:sec];
navController.modalPresentationStyle = UIModalPresentationOverCurrentContext;
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:navController animated:YES completion:^{
}];
I have 5 view controller and want to come back from the last view to 1st view controller
Call a function in which you have to change the app rootviewcontroller. set it as a navigationController
yourViewcontoller *viewController = [[yourViewContoller alloc] init];
UINavigationController *navController=[[UINavigationController alloc]initWithRootViewController:viewController];
self.window.rootViewController = navController;
If you're using storyboards, give the UINavigationController a Storyboard ID. You can then initiate it and present through the code:
UINavigationController *vc = [self.storyboard instantiateViewControllerWithIdentifier:#"<Storyboard ID>"];
[self presentViewController:vc animated:YES completion:nil];
Use this method on Animation splash screen
[self performSelector:#selector(setHidden:) withObject:nil afterDelay:2.0];
-(void) setHidden:(id)sender
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboare" bundle:nil];
YourVC* vController = (YourVC*)[Storyboard instantiateViewControllerWithIdentifier:#"storyboardId"];
UINavigationController *navcotoller=[[UINavigationController alloc]initWithRootViewController:vController];
self.window.rootViewController =navcotoller;
}
If you are using UINavigationController you could and should simply call
[self.navigationController popToRootViewControllerAnimated:YES];
I've got the iPhone working fine with creating a segue programmatically.
e.g.
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard_iPhone"
bundle:nil];
FooBarViewController *foobarViewController = (FooBarViewController *)[storyboard instantiateViewControllerWithIdentifier:#"foobarViewControllerID”];
[self.navigationController pushViewController:foobarViewController animated:YES];
Now I'm trying to do something similar on the iPad storyboard.
The goal being to programmatically change the detail view to a view on the storyboard.
I thought maybe:
[self.splitViewController.navigationController presentViewController:foorbarViewController animated:NO completion:nil];
However this doesn't work. Any suggestions?
I believe I've solved my own question with the following function:
- (void) presentDetailView : (UIViewController *) viewcontroller {
UINavigationController *detailNavCtrl = [[UINavigationController alloc] initWithRootViewController:viewcontroller];
detailNavCtrl.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
detailNavCtrl.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[[[self.splitViewController viewControllers] lastObject] presentViewController:detailNavCtrl animated:NO completion:nil];
}
I have a certain UINavigationController in storyboard I present modally from another view controller:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UINavigationController *myNavController = [storyboard instantiateViewControllerWithIdentifier:#"myNavController"];
[self presentViewController:myNavController animated:YES completion:nil];
This navigation controller has set another UIViewController as its root view controller in storyboard. I'd like to set some properties for this root view controller before it is shown, but I tried this:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UINavigationController *myNavController = [storyboard instantiateViewControllerWithIdentifier:#"myNavController"];
[self presentViewController:myNavController animated:YES completion:nil];
MyRootViewController *myRootViewController = [storyboard instantiateViewControllerWithIdentifier:#"myRootViewController"];
[myRootViewController setSelectedItem:selectedItem];
[myRootViewController setDelegate:self];
But the root view controller doesn't seem to be loaded yet when I try to set its properties...
How could I do this? Thanks
If you had debugged, you will find the myRootViewController made by MyRootViewController *myRootViewController = [storyboard instantiateViewControllerWithIdentifier:#"myRootViewController"];
isn't the myNavController's real rootViewController.
This method -instantiateViewControllerWithIdentifier: just give you a whole new UIViewController instance.
So, If you want get the real rootViewController, just replace it with following:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UINavigationController *myNavController = [storyboard instantiateViewControllerWithIdentifier:#"myNavController"];
MyRootViewController *myRootViewController = myNavController.viewControllers[0];
[myRootViewController setSelectedItem:selectedItem];
[myRootViewController setDelegate:self];
[self presentViewController:myNavController animated:YES completion:nil];
Hi, this is my storyboard , i wanna go from First view controller to LoggedinViewController.
Im normally using
[self performSegueWithIdentifier:#"s1" sender:self];
but if i add tab bar controller this line is not working , how can i fix this ?
You can use the following if you have embedded into navigation controller.
UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:#"Story_Board_Name" bundle:nil];
UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:#"TABid"];
self.tabBarController.selectedIndex = 0;
[self.navigationController pushViewController:self.tabBarController animated:YES];
Or try this
UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:#"Story_Board_Name" bundle:nil];
UITabBarController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:#"TABid"];
self.tabBarController.selectedIndex = 0;
[self performSegueWithIdentifier:#"s1" sender:self];
Give your tabbarcontroller an identifier from the storyboard, the do something like this
UIStoryboard *myStoryBoard =[UIStoryboard storyboardWithName:#"Your_Story_Board_Name" bundle:nil];
TabViewController *tabBarController = [myStoryBoard instantiateViewControllerWithIdentifier:#"TAB_Identifier"];
[self presentViewController:tabBarController animated:YES completion:nil];
Hope this helps
first give "tabbarid" to that tab inside storyboard
UITabBarController *tabBarController1 = [self.storyboard instantiateViewControllerWithIdentifier:#"tabbarid"];
tabBarController1.selectedIndex = 1;
[self presentViewController:tabBarController1 animated:YES completion:nil];
