I want to make the bottom button seen in the storyboard on the right to take the user to the signupstoryboard.storyboard/signupController seen on the left when the user taps on the button. How can that be done?
{ - (IBAction)signupbutton:(id)sender; SignupController *signUpView = [self.storyboard instantiateViewControllerWithIdentifier:#"signup"]; [self presentViewController:signUpView animated:YES completion:nil]; }
You'll have to do it by code.
- (IBAction)buttonTapped
{
NSString *storyboardName = #"signupstoryboard";
UIViewController *nextViewController = [[UIStoryboard storyboardWithName:storyboardName bundle:nil] instantiateInitialViewController];
// if you are using a navigation controller to push it:
[self.navigationController pushViewController:nextViewController animated:YES];
// otherwise if you are presenting it modally:
[self presentViewController:nextViewController animated:YES completion:nil]
}
In your .m (at the top)
#import "signupController.h"
In your button action method (Don't forget to set the storyboard id for your signupController as signup
- (IBAction)signupbutton:(id)sender
{
SignupController *signUpView = [self.storyboard instantiateViewControllerWithIdentifier:#"signup"]; [self presentViewController:signUpView animated:YES completion:nil];
}
Thats it

I have view controller and implement like this :
loginViewController = [[LoginViewController alloc] init];
loginViewController.delegate = self;
[self.view addSubview:loginViewController.view];
[self addChildViewController:loginViewController];
[loginViewController didMoveToParentViewController:self];
Inside loginViewController, I want to show another view controller but I implement like this :
otherViewController = [[OtherViewController alloc] initWithNibName:nil bundle:nil];
otherViewController.delegate = self;
[self presentViewController:otherViewController animated:YES completion:nil];
Everytime I done with otherViewController and want to dismiss the view controller [self dismissViewControllerAnimated:YES completion:nil];
it restarted from the beginning and not showing the loginViewController. I tried to check using Debug View Hierarchy and got that no loginViewController is implemented when I called presentViewController:otherViewController
Why is this happened ?
I have a view controller named ViewController.
ViewController displays a UIView that has a button on it, which allows me to advance to a second view controller - SecondViewController.
SecondViewController also has a button on it, which allows me to advance to a third view controller.
However, I am having trouble displaying ThirdViewController. When I tap the button in SecondViewController it throws an error:
Warning: Attempt to present ... on ... whose view is not in the window hierarchy!
I have been to a bunch of other sites and posts that address this issue, but cannot seem to find a working solution. I have implemented quite a few solutions, but none seem to work.
Here is my code:
- (void)secondaryView:(UIView *)secondaryView
{
UIView *theView = secondaryView;
UIViewController *viewController = [[UIViewController alloc] init];
viewController.view.frame = [UIScreen mainScreen].bounds;
[viewController.view addSubview:theView];
viewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:viewController animated:YES completion:nil];
}
secondaryView is a UIView that I am constructing elsewhere in the application. I add it to the viewController then present the viewController.
Is there any way to dynamically create UIViewControllers, add a UIView to each one, and add them to the window hierarchy?
If you can use navigation in your ViewControllers, you can try the below code
In the place where you call the firstViewController,
-(void)callFirst
{
FirstViewController *first = [FirstViewController alloc] init];
UINavigationController *navigationController = [UINavigationController alloc] initWithRootViewController:first];
navigationController.modalPresentaionStyle = UIModalPresenationFormSheet;
[self presentModalViewController:navigationController animated:YES];
}
And in the FirstViewController button action ,you can write
-(void)callSec
{
SecondViewController *sec = [SecondViewController alloc] init];
[self.NavigationController pushViewController:sec animated:YES];
}
And in SecondViewController you can do the same
-(void)callThird
{
ThirdViewController *third = [ThirdViewController alloc] init];
[self.NavigationController pushViewController:third animated:YES];
}
Try this...And in these ViewControllers you can do whatever coding you want to meet the requirement like
-(void)viewDidLoad
{
UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(20,20,400,400)];
newView.backGroundColor = [UIColor redColor];
[self.view addSubView:newView];
}
I want to be able to open a ViewController from a different class. So I could simply call it to open a view wherever I need it.
So I have this setup in the class that holds the code:
+ (void)openCalcView: (NSString *)nameOfView {
UIViewController *controller;
if ([nameOfView isEqualToString:#"Tax"]) {
controller = [[TAXViewController alloc]initWithNibName:#"TAXViewController" bundle:nil];
}else if ([nameOfView isEqualToString:#"Rent"]){
controller = [[RENTViewController alloc]initWithNibName:#"RENTViewController" bundle:nil];
}
controller.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentViewController:controller animated:YES completion:nil];
[controller release];
}
But [self presentViewController:controller animated:YES completion:nil]; gives me a warning:
Class method '+presentViewController:animated:completion:' not found (return type defaults to 'id')
I can call simple things like NSLog through this, from any class. But this doesn't work.
Because openCalcView is a Class method, there is no UIViewController instance (i.e. no [self presentViewController:] method).
You'll need to also pass a UIViewController to this class method, something like this:
+ (void)openCalcView: (NSString *)nameOfView fromViewController:(UIViewController *)controller {
UIViewController *newController;
if ([nameOfView isEqualToString:#"Tax"]) {
newController= [[TAXViewController alloc]initWithNibName:#"TAXViewController" bundle:nil];
}else if ([nameOfView isEqualToString:#"Rent"]){
newController= [[RENTViewController alloc]initWithNibName:#"RENTViewController" bundle:nil];
}
newController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[controller presentViewController:newController animated:YES completion:nil];
[newController release];
}
the controller parameter represents the UIViewController that is opening the new view controller
I want to make it seem as if it was a reset button.
It would take me to my mainviewcontroller screen and then come right back.
MainViewController.m
MainViewController.h
MainViewController.xib
ViewController.xib
ViewController.m
ViewController.h
I do not understand how I am supposed to do this.....
- (IBAction)newGame:(id)sender {
[self dismissModalViewControllerAnimated:YES];
ViewController *screen = [[ViewController alloc] inittWithNibName:#"ViewController" bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:screen animated:YES];
}
Any ideas of how to do this?
Thanks
Do that without animation, as following.
- (IBAction)newGame:(id)sender {
[self dismissModalViewControllerAnimated:NO];
ViewController *screen = [[ViewController alloc] inittWithNibName:#"ViewController" bundle:nil];
screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:screen animated:NO];
}
I have two view controllers: firstViewController and secondViewController. On the firstViewController I have a button. How can I change the view when I touch the button?
- (IBAction)change {
secondViewController* viewController = [[secondViewController alloc] init];
[self.navigationController pushViewController:viewController animated:YES];
[viewController release];
}
