I am really confused about the relationship between storyboards and pushing to views programmatically.
I am using SWRevealViewController to display a menu of items.
If I push to the storyboard using
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
PhotosViewController *controller = [storyboard instantiateViewControllerWithIdentifier:#"PhotosViewController"];
[self presentModalViewController:controller animated:YES];
[self.navigationController pushViewController:controller animated:YES];
All of the information in my storyboard is displayed but there is no "back" button to the SWRevealViewController.
If I push to the view controller using
PhotosViewController *frontViewController = [[StreamScreen alloc] init];
newFrontController = [[UINavigationController alloc] initWithRootViewController:frontViewController];
Then I can view everything that I have added programmatically but nothing from the storyboard.
My question is how can I access things from both storyboard and things Ive added programmatically.
if you present the view controller then it will not give you default back button because when you present a controller it will not added in navigation stack of NavigationController so it won't give you that option.
If you want push controller do not use presentModalViewController.
Try like below
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
PhotosViewController *controller = [storyboard instantiateViewControllerWithIdentifier:#"PhotosViewController"];
[self.navigationController pushViewController:controller animated:YES];
and if you want to present controller then create manually add a back button like we have default in navigation back button and on it's click write below code to dismiss the controller.
[self dismissViewControllerAnimated:YES];
Hope this helps you.

For sidemenu I am using the SWRevealViewController framework and For tab-bar I am taking 3 Viewcontrollers example A, B and C. I want to display tab bar in initial Viewcontroller for that purpose in didfinishlaunch
method in app delegate. I have mentioned front viewcontroller as tab-bar and rear Viewcontroller as side menu and I am also successful in moving to side menu. But from that side menu I am unable to navigate the view controller. Please suggest me
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
SideMenuViewController *sidemenuVc = [storyboard instantiateViewControllerWithIdentifier:#"SideMenuViewController"];
HomeViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"HomeViewController"];
SWRevealViewController *revealController = [[SWRevealViewController alloc] initWithRearViewController:sidemenuVc frontViewController:vc];
//[self .navigationController.pushViewController:vc animcated:YES];
[self.navigationController pushViewController:revealController animated:YES];
You should create storyboard like this
or try below one
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:...
I don't know if this is possible or not but I wrote a project using xibs and want to modally switch to a storyboard project.
I know that to switch VC's you do something like
NewViewController *NewVC = [[NewViewController alloc] init];
[self presentModalViewController:NewVC animated:YES];
upon clicking a button, that I'll call "switch"
There is another project using solely storyboards that I want to call using "switch"
How do I go about doing this? Is it possible to do this?
Yes it is possible. You can do something like this:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"YourStoryboardName" bundle:nil];
MainMenuViewController *mainmenuvc = [storyboard instantiateViewControllerWithIdentifier:#"mainMenuViewController"];
[self.navigationController pushViewController:mainmenuvc animated:YES];
EDIT
If I understand your comment, you want to change the root view controller. You can do so by:
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"RVCStoryboard" bundle:nil];
MainMenuViewController *mainmenuvc = [storyboard instantiateViewControllerWithIdentifier:#"mainMenuViewController"];
[[UIApplication sharedApplication].delegate].window.rootViewController = mainmenuvc;
Please note that for this to work, in your RVCStoryboard you have to select the viewcontroller you are trying to load, and assign a name to it so that the instantiateViewControllerWithIdentifier: method will work. Check the attached image, the field "Storyboard ID":
I have a series of views that are managed under a Navigation Controller. Is there a way to programmatically (in iOS5+) jump (push/pop) to different views? For instance, I have
NavigationController->RootViewController->DetailViewController1->DetailViewController2->DetailViewController3
How can I, say, jump from RootViewController to DetailViewController3, and then jump back to DetailViewController1?
Thanks.
You can try something like this.
Get your VCs from storyboard. (You have to set identifiers in storyboard)
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UIViewController *DetailViewController1 = [storyboard instantiateViewControllerWithIdentifier:#"DetailViewController1Identifier"];
UIViewController *DetailViewController3 = [storyboard instantiateViewControllerWithIdentifier:#"DetailViewController3Identifier"];
Push VCs way you need.
[self.navigationController pushViewController:(DetailViewController1) animated:YES];
[self.navigationController pushViewController:(DetailViewController3) animated:YES];
Now, when you press "back" you'll see DetailViewController1.
