simple question... My app starts out with a UINavigationController with a UIViewController (of course), but when a button is pressed, I want another UINavigationController to be presented.
Would I do:
[self.navigationController presentViewController:AnotherNavigationController animated:YES completion:nil];
or:
[self presentViewController:AnotherNavigationController animated:YES completion:nil];
Both ways work... But I'm not sure which one is correct... And also, I can't seem to get the BarButtonItem's to appear once that navigationcontroller is presented
PS. The navigationcontroller has a tabbarcontroller with two tab views in it
Thanks in advanced!
Try this:
[self.navigationController pushViewController:AnotherNavigationController animated:YES];
Use push segue instead.
try this code:
after login sucess
UIStoryboard *Story_TabController = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil]
UIViewController *class1 = [Story_TabController instantiateViewControllerWithIdentifier:#"Feed_ViewController"];
UIViewController *class = [Story_TabController instantiateViewControllerWithIdentifier:#"FindFriends_ViewController"];
UINavigationController *nav_profile=[[UINavigationController alloc]initWithRootViewController:class1];
UINavigationController *nav_post=[[UINavigationController alloc]initWithRootViewController:class2];
Tab_controller.viewControllers=[NSArray arrayWithObjects:nav_profile,nav_post, nil];
Tab_controller.selectedIndex=0;
[self.navigationController pushViewController:Tab_controller animated:YES];

I have a situation wherein a storyboard made VC(embedded in NavController) should be presented programmatically.
SomeVC -> presents NavController(rootVC) -> rootVC -> pushes subVC
on this representation, subVC should have a back button to go back to rootVC, but I can't implement it this way. Will be providing sample codes that I have already tried.
this pushes the rootVC directly:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"storyBoard" bundle: nil];
UIViewController * vc = [storyboard instantiateViewControllerWithIdentifier:#"rootVC"];
[self.navigationController presentViewController:vc animated:YES completion:nil];
also tried pushing the navigationController itself, ID has been set on storyboard:
UINavigationController *navController = [storyboard instantiateViewControllerWithIdentifier:#"navigationController"];
[self presentViewController:navController animated:YES completion:nil];
EDIT: storyboard implementation looks like this
I'm not sure if I understand you correctly. You want to present a navigation controller and have those rootVC and subVC already in it, right? So after presenting, you want the subVC to be presented with the back button right away.
If that's the case you need to tell the navigation controller to push the subVC before presenting it
UINavigationController *navController = [storyboard instantiateViewControllerWithIdentifier:#"navigationController"];
UIViewController *subVC = [storyboard instantiateViewControllerWithIdentifier:#"subVC"];
[navController pushViewController:subVC animated:NO];
[self.navigationController presentViewController:vc animated:YES completion:nil];
I want to push to a new viewcontroller from a presented viewcontroller. I don't want to dismiss the presented viewcontroller. I want the new viewcontroller to come over the presented viewcontroller.
Can anybody tell me how to do that.
You do not push form the presented controller so the best option is
First you have to dismiss the controller without animation and then in the method of -(void)viewWillApper you can easly push to the controller where you want to push.
You can do by using UINavigationController like
UINavigationController *vcObject = [[UIStoryboard storyboardWithName:#"Main" bundle:nil] instantiateViewControllerWithIdentifier:#"YourViewController"];
[self.navigationController presentViewController:vcObject animated:YES completion:NULL];
Now you can easily push or pop to other ViewController like you want.Thankyou
Open your modalView controller as a new rootViewController :
UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:nextViewController];
[self.navigationController presentViewController: navController animated:YES completion:nil]
I want to add a navigationcontroller to an existing viewcontroller which is created using storyboard, i have embed it in a navigation controller, but the code for navigating (shown below) is not working even after embed in the navigation controller:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
EditProfileViewController *nextViewController = [storyboard instantiateViewControllerWithIdentifier:#"EPVController"];
[self.navigationController pushViewController:nextViewController animated:YES];
When i have tried to log self.navigationController, it shows null.
Update: It is fine when i am trying with presentViewcontroller , but i
want to push the viewcontroller with navigationController.
I am struggling with this for two days,Please help.
If self is a subclass of UINavigationController, you do not need to refer to the navigationController property. (Note that this won't work if EditProfileViewController is also a subclass of UINavigationController, as you can't push a UINavigationController inside a UINavigationController).
EditProfileViewController *nextViewController = [storyboard instantiateViewControllerWithIdentifier:#"EPVController"];
[self pushViewController:nextViewController animated:YES];
Otherwise, if you don't have a pre-existing navigation controller
EditProfileViewController *nextViewController = [storyboard instantiateViewControllerWithIdentifier:#"EPVController"];
[self presentViewController:nextViewController animated:YES completion:nil];
I used code from this question Display UIViewController as Popup in iPhone it is working fine but I don't want to use segue or I can say I can't use segue because all the code is created programmatically, so I cant set segue on button.
I used this code but it didn't work
- (IBAction)open:(id)sender {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *newVC = (UIViewController *)[storyboard instantiateViewControllerWithIdentifier:#"Second"];
[ViewController setPresentationStyleForSelfController:self presentingController:newVC];
[self.navigationController pushViewController:newVC animated:YES];
}
Edit 1:
View after popup
You should check if this VC self.navigationController is not nil. and i think you want to presentViewController: not pushViewController:...
In MyMainViewController, I present a navigation controller like this:
UIStoryboard* storyboard = [UIStoryboard storyboardWithName:#"Main_iPhone" bundle:nil];
UINavigationController* nc = [storyboard instantiateViewControllerWithIdentifier:#"NAVIGATION_CONTROLLER_ID"];
[self presentViewController:nc animated:YES completion:nil];
Later, from somewhere within the view hierarchy of the UINavigationController, I need to return to MyMainViewController. How can I do this?
(Note: MyMainViewController is defined in a .XIB, and not in the storyboard where the UINavigationController and it's children are defined.)
It sounds like you have modally presented a NavController that you want to remove. Modally presented VC's can remove themselves.
Somewhere in your NavController add:
[self dismissViewControllerAnimated:YES completion:^{
NSLog(#"Dismissed nav controller modally");
}]
[self.navigationController popToViewController:[[self.navigationController viewControllers] objectAtIndex:2] animated:YES];
I gues you know the index of your view controller. If you simply want to return to the rootViewController you can do it like
[self.navigationController popToRootViewControllerAnimated:YES];
If you want to push new viewController to the navigation stack just do it like
MyMainViewController *mainController = [[MyMainViewController alloc] initWithNibName:#"MyMainViewController" bundle:nil];
[self.navigationController pushViewController:desController animated:YES];
Returning to the previous viewController would be
[self dismissViewControllerAnimated:YES completion:nil];
