Remove PageViewController - ios

Question

I've used a tutorial on AppCoda for adding a sort of tutorial style UIPageViewController - it works amazingly - it's just that I can't remove it on a button click.
Here's my PageViewController:
#import "startupViewController.h"
#import "SKSlideViewController.h"
#import "APPChildViewController.h"
#interface startupViewController ()
#end
#implementation startupViewController
#synthesize outletWallpaper;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self mymethod];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)mymethod {
self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
self.pageController.dataSource = self;
[[self.pageController view] setFrame:[[self view] bounds]];
APPChildViewController *initialViewController = [self viewControllerAtIndex:0];
NSArray *viewControllers = [NSArray arrayWithObject:initialViewController];
[self.pageController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
[self addChildViewController:self.pageController];
[[self view] addSubview:[self.pageController view]];
[self.pageController didMoveToParentViewController:self];
}
- (APPChildViewController *)viewControllerAtIndex:(NSUInteger)index {
APPChildViewController *childViewController = [[APPChildViewController alloc] initWithNibName:#"APPChildViewController" bundle:nil];
childViewController.index = index;
return childViewController;
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController {
NSUInteger index = [(APPChildViewController *)viewController index];
if (index == 0) {
return nil;
}
// Decrease the index by 1 to return
index--;
return [self viewControllerAtIndex:index];
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController {
NSUInteger index = [(APPChildViewController *)viewController index];
index++;
if (index == 3) {
return nil;
}
return [self viewControllerAtIndex:index];
}
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {
// The number of items reflected in the page indicator.
return 3;
}
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {
// The selected item reflected in the page indicator.
return 0;
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
NSLog(#"Switching View Controllers...");
SKSlideViewController *slideController=(SKSlideViewController *)[segue destinationViewController];
[slideController setStoryBoardIDForMainController:#"MainVC" leftController:#"LeftVC" rightController:#"RightVC"];
[slideController reloadControllers];
}
#end
This code sends me to another file which from there, I need to remove the whole thing.

Answer 1

I think I did the same tutorial on appcoda, and had the same question!
A solution that has worked for me I stumbled across accidentally on another question:
// Replace deleteVC with your UIPageViewController
[deleteVC willMoveToParentViewController:nil];
[deleteVC.view removeFromSuperview];
[deleteVC removeFromParentViewController];

Answer 2

var movingIndex = 0
var forwardDirection = false
if selectedIndex == images.count{ //ur pages dataSource You may not need this
movingIndex = selectedIndex - 1
forwardDirection = false
} else {
movingIndex = selectedIndex
forwardDirection = true
}
controllers.remove(at: selectedIndex)
capturedInspectionPhotoView.imagePageController?.dataSource = self
capturedInspectionPhotoView.imagePageController?.setViewControllers([controllers[movingIndex]],
direction: forwardDirection ? .forward : .reverse, animated: true)
