UIPageViewController Swipe Programmatically - ios

Question

I have been unable to find a solution to this issue that resolves my case. I am looking to call the two blocks of code that swipe my page view controller programmatically.
Such as a [self viewControllerAfterViewController:self] that would call the last block of code.
In viewDidLoad
[super viewDidLoad];
indexvalue = 1;
NSLog(#"main intitated");
// Do any additional setup after loading the view, typically from a nib.
self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"PageViewController"];
self.pageViewController.dataSource = self;
ViewController *tvc = [self.storyboard instantiateViewControllerWithIdentifier:#"Main"];
Request *pvc;
viewcontrollers =[NSArray arrayWithObjects:tvc, pvc, nil];
[self.pageViewController setViewControllers:viewcontrollers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];
self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
[self addChildViewController:pageViewController];
[self.view addSubview:pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];
Code to swipe between screens called by swipe gesture
-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
{
NSLog([NSString stringWithFormat:#"%i", indexvalue]);
if (indexvalue == 0 & check0 < 1) {
check0 = 1;
ViewController *tvc = [self.storyboard instantiateViewControllerWithIdentifier:#"Main"];
indexvalue = 1;
return tvc;
}
else {
return nil;
}
}
-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
NSLog([NSString stringWithFormat:#"%i", indexvalue]);
if (indexvalue == 1 & check1 < 1) {
check1 = 1;
Request *pvc = [self.storyboard instantiateViewControllerWithIdentifier:#"Friends"];
indexvalue = 0 ;
return pvc;
}
else {
return nil;
}
}

viewcontrollers =[NSArray arrayWithObjects:tvc, pvc, nil];
replace with
viewControllers = #[tvc];
viewControllers= [self viewControllerAtIndex:0];
Now add this method
- (UIViewController *)viewControllerAtIndex:(NSUInteger)index
{
if (([self.pageTitles count] == 0) || (index >= [self.pageTitles count])) {
return nil;
}
if (index == 0) {
//first view
ViewController *pageContentViewController2 = [self.storyboard instantiateViewControllerWithIdentifier:#"ViewController"];
return pageContentViewController2;
}
//second view
Request *pageContentViewController3 = [self.storyboard instantiateViewControllerWithIdentifier:#"Request"];
return pageContentViewController3;
}
