I added one ViewController to my project and created one class.
After I bind this class to my ViewController.
In another controller I have method:
- (IBAction)login:(id)sender {
// How here I can do redirect to controllerViewController
}
There are two ways to push view controllers in the application.
1) by Segue
2) By View controller identifier
1) By Segue :
[self performSegueWithIdentifier:"SegueIdentifier" sender:self];
2) By View controller identifier :
Yourclassname *gotoYourClass = [self.storyboard instantiateViewControllerWithIdentifier:#"ViewControllerIdentifier"];
[self.navigationController pushViewController:gotoYourClass animated:YES];
- (IBAction)login:(id)sender {
ViewController *vc = [[ViewController alloc]initWithNibName:#"ViewController" bundle:nil];
[self presentViewController:vc animated:YES completion:nil]; }
In the storyboard give your view controller an identifier (under the Attributes Inspector) then use the following code, to bring that view forward.
IF YOU WANT TO USE PUSH THEN USE THIS CODE
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"STORYBOARDNAME" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:#"VIEWCONTROLLERIDENTIFIER"];
[self.navigationController pushViewController:vc animeted:YES];
IF YOU WANT TO PRESENT THEN USE THIS CODE
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"STORYBOARDNAME" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:#"VIEWCONTROLLERIDENTIFIER"];
[self presentModalViewController:vc animated:YES];
Note: In UIViewController please enter your view controller name which you want to push into another view.
If you want to comeback to the current ViewController later then use Navigation ViewController or else just use the presentedViewController of self(your current viewController)- no going back business, like they have previously illustrated.
For a simple block of execution(demo or practice) it's all the same but for a project application it completely matters to make the correct choice.

I have created storyboard which I want to open on top of another view or in childView so that when I close or destroy this view of storyboard the earlier view on which the storyboard is opened remains the same.
When I run the following code:-
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPad" bundle:nil];
ViewController *detailViewController = [storyboard instantiateViewControllerWithIdentifier:#"neolick"];
[[UIApplication sharedApplication].keyWindow setRootViewController:detailViewController];
First, the storyboard opens but I don't know whether it opens on top of previous view or it destroys the previous view & then open.
Second, the functions needed on that storyboard runs automatically which is as I want but how these things are working.
If anyone can help me understand the above code and its working.
NOTE: I cannot call the earlier view again in same state because of some reason.
Thanks in Advance!!
Here you are setting root view controller
it will not keep your back screen as it is what you want
If you want to keep current screen and show other screen on that
you have two approaches
1) Present ViewController
2) Push View Controller
1) Present ViewController
for this you can present your screen on top of other screen which is visible
for example
- (IBAction)btnNextTapped:(id)sender {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPad" bundle:nil];
ViewController *detailViewController = [storyboard instantiateViewControllerWithIdentifier:#"neolick"];
[self presentViewController:detailViewController animated:true completion:nil]
}
2) Push View Controller
For that you need NavigationController and need to push your ViewController from current visible screen
i.e
[self.navigationController pushViewController:vc animated:true];
EDIT
as per discussion you need to find current top view controller then you should present it
Add this method below your method
- (UIViewController*) topMostController
{
UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;
while (topController.presentedViewController) {
topController = topController.presentedViewController;
}
return topController;
}
And Replace this method with code
- (void)goToNewPage:(CDVInvokedUrlCommand*)command
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main_iPad" bundle:nil];
ViewController *detailViewController = [storyboard instantiateViewControllerWithIdentifier:#"neolick"];
[[self topMostController] presentViewController:detailViewController animated:true completion:nil];
}
I got a source code for an existing app. throughout the app the developer didn't use storyboard for the user interface but rather he used interface builder xib files. As a new developer, i don't know how to develop iOS apps in xcode using xib files for viewcontrollers, i learnt the storyboard way. Now I want to add more screens to the apps source code, i created a new storyboard file to define my new screens, how do I navigate to the entry point of this new storyboard from a button action i defined in one of the xib files so that i can easily implement my features.
while searching i got some suggestions like this one
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"newStoryboard_iPhone" bundle:nil];
MyNewViewController *myVC = (MyNewViewController *)[storyboard instantiateViewControllerWithIdentifier:#"myViewCont"];
but i dont think i understand how to implement this even if this can be in a button IBAction method. and besides subsequent navigations would be segues through the view controllers i define in the new storyboard
It's right suggestion.
You should get storyboard object by its name. Then you should create your viewController using [storyboard instantiateViewControllerWithIdentifier:#"..."];
Then you may navigate to your new VC using appropriate navigation method. For example:
[self.navigationController pushViewController:vc animated:YES]
ViewController identifier you should set in Interface Builder under section "Identity Inspector" in field "Storyboard ID".
That code you should place in IBAction method. But better would be to extract it in separate method. Something like this:
- (IBAction)buttonPressed:(UIButton *)sender {
[self navigateToMyNewViewController];
}
- (void)navigateToMyNewViewController {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"myNewStoryboard" bundle:nil];
MyNewViewController *myNewVC = (MyNewViewController *)[storyboard instantiateViewControllerWithIdentifier:#"MyNewViewController"];
[self.navigationController pushViewController:myNewVC animated:YES];
}
Navigation from MyNewViewController your can implement as you want. It may be segues.
MyNewViewController *myVC = [self.storyboard instantiateViewControllerWithIdentifier:#"YOUR_VC_NAME_HERE"];
This will instantiate your ViewController, from here you can present it like so
[self presentViewController:myVC animated:YES completion:nil]
The image shows where you set the storyboard name that you're referring to
Try This it's working for me ,
Use below line of code :
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main"bundle:nil];
LoginViewController *loginVC = (LoginViewController*)[storyboard instantiateViewControllerWithIdentifier:#"LoginViewController"];
[self.navigationController pushViewController:loginVC animated:YES];
We need to set storyboard id as per mention in below,
you can navigate one storyboard to another storybord:
first you import your viewcontroller class to appdelegate.h
AppDelegate *appDelegateTemp = [[UIApplication sharedApplication]delegate];
appDelegateTemp.window.rootViewController = [[UIStoryboard storyboardWithName:#"storyboard_name" bundle:[NSBundle mainBundle]] instantiateInitialViewController];
Like the way you use storyboard, use
MainViewController *mainVC = [[MainViewController alloc] initWithNibName:#"MainViewController" bundle:nil]
[self.navigationController pushViewController:mainVC animated:YES];
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:...
How can you push to another view controller without prepareForSegue?
myClassVC *viewController = [myClassVC alloc];
UIStoryboardSegue *segue = [[UIStoryboardSegue alloc] initWithIdentifier:#"pushToMyVC" source:self destination:viewController];
if ([segue.identifier isEqualToString:#"pushToMyVC"]) {
NSLog(#"logging");
myClassVC *viewController = (myClassVC *)[segue destinationViewController];
[self presentViewController:viewController animated:YES completion:nil];
}
If you want to programmatically invoke a push segue, you give the segue a "storyboard id" in Interface Builder and then you can:
[self performSegueWithIdentifier:"pushToMyVC" sender:self];
Alternatively, if you don't want to perform the segue, you can instantiate the destination view controller and then manually push to that view controller. All you need to do is to make sure that the destination view controller has its own "storyboard id" in Interface Builder, then you can:
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"DestinationController"];
[self.navigationController pushViewController:controller animated:YES];
You said "push" (and hence I used pushViewController above). If you really meant to "present a modal view controller", then that second line is:
[self presentViewController:controller animated:YES completion:nil];
As you can see, you don't have to use prepareForSegue to push to new scene. You only use prepareForSegue if you want to pass information to the destination view controller. Otherwise it is not needed.
Clearly, if you're not using storyboards (e.g., you're using NIBs), then the process is entirely different. But I assume you're not using NIBs because prepareForSegue is not applicable in that environment. But if you were using NIB, it would be as follows:
SecondViewController *controller = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
[self.navigationController pushViewController:controller animated:YES];
[self presentViewController:viewController animated:YES completion:nil]; is not needed, as the segue will push the destination view controller using the transition you selected automatically.
If you don't want to use the segue process you'll need to manually push the view controller with:
[self presentViewController:viewController animated:YES completion:nil];
but make sure you remove the segues in the Storyboard first.
NSString * storyboardName = #"Main";
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:storyboardName bundle: nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"SecondViewControllerID"];
[self presentViewController:vc animated:YES completion:nil];
In my case all viewControllers are built dynamically. I do not make use of the storyboard for this purpose. Should this be your case you may just instantiate the viewController class you want to open and make a push as in my example below:
MyViewController* myViewController = [[MyViewController alloc] init];
[self.navigationController pushViewController:myViewController animated:YES];
There is probably a simple solution but I can't figure it out.
I am using storyboards for the interface.
I start with a tab bar controller, but before the user is allowed to use the app the user has to authenticate himself trough a loginview which is modally pushed at the start.
I want to configure the loginview at the same storyboard, but I can't seam to figure out how to link the view controller at the storyboard and my code.
What I have done:
Create a new UIViewController subclass trough file > new > new file.
Drag a new UIViewController in the story board
Set the class in the custom class tab
drags a UILabel for test purpose.
run
No label...
Pull on a new UIViewController that will act as the login view controller onto the MainStoryboard. In the attribute inspector change the identifier to LoginViewController (or something appropriate). Then add
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:#"LoginViewController"];
[vc setModalPresentationStyle:UIModalPresentationFullScreen];
[self presentModalViewController:vc animated:YES];
}
to the First view controller and the login screen will be loaded from your storyboard and presented.
Hope this helps.
The answer by Scott Sherwood above is most correct answer I found after lot of searching. Though very slight change as per new SDK (6.1), presentModalViewController shows deprecated.
Here is very small change to above answer.
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Storyboard" bundle:nil];
HomeViewController * hvc = [sb instantiateViewControllerWithIdentifier:#"LoginView"];
[hvc setModalPresentationStyle:UIModalPresentationFullScreen];
[self presentViewController:hvc animated:YES completion:nil];
I'm new in this field. But if the first view controller is a navigation view controller and its rootviewcontroller is a table view controller. If you want to push a view controller like the LoginViewController when you click the cell, and you also want to go back to the table view by using the navigation bar. I recommend this way:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UIStoryboard *sb = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *controller = [sb instantiateViewControllerWithIdentifier:#"LoginViewController"];
[self.navigationController pushViewController:controller animated:YES];
}
In this way, you can have the navigation.
By the way, I don't know why this kind of problem you asked will appear. I guess when the loginviewcontroller is created in the code, its view is not the view in the storyboard. If someone know the cause, please tell me! thanks!
