UIPageViewController with Button to next view - ios

Question

I use a UIPageViewController for two view controllers. In the first view controller I have a 'NEXT' button to go to the second view controller. My question is: How can I wire it up?
In my first and second view controllers I do not have code yet. However, in my RootViewController I have this code:
- (void)viewDidLoad {
self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"PageViewController2"];
self.pageViewController.dataSource = self;
SeekerRegistrasiViewController *tvc = [self.storyboard instantiateViewControllerWithIdentifier:#"seeker1"];
Seeker2RegistrasiViewController *pvc;
self.array =[NSArray arrayWithObjects:tvc, pvc, nil];
[self.pageViewController setViewControllers:self.array direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:nil];
self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height -60);
self.pageViewController.view.backgroundColor = [UIColor clearColor];
[self addChildViewController:pageViewController];
[self.view addSubview:pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];
}
-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController{
if ([viewController isKindOfClass:[Seeker2RegistrasiViewController class]]) {
SeekerRegistrasiViewController *pvc = [self.storyboard instantiateViewControllerWithIdentifier:#"seeker1"];
return pvc;
}
else return nil;
}
-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController{
if ([viewController isKindOfClass:[SeekerRegistrasiViewController class]]) {
Seeker2RegistrasiViewController *tvc = [self.storyboard instantiateViewControllerWithIdentifier:#"seeker2"];
return tvc;
}
else return nil;
}
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {
return 2;
}
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {
return 0;
}
I would appreciate any help that would guide me in the right direction.

You can do it using setViewControllers:direction:animated:completion:.
Look at this answer: Is it possible to Turn page programmatically in UIPageViewController?
You basically set again all the view controllers (already switched), define a direction (which the animation will use, for example, UIPageViewControllerNavigationDirectionForward), use YES for animated and a completion block for processing afterwards (like updating the currentPage index you manage).
