Push view controller not working

Question

I'm using UINavigation and UIPageView controller in a UIViewController. I have 3 buttons and here is my code :

- (IBAction)StartButtonClicked:(id)sender {
     NSLog(@"start button pressed");
     [_Timer invalidate];
     _Timer = nil;

     dispatch_async(dispatch_get_main_queue(), ^{
         UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
         CardViewController* controller = [storyboard instantiateViewControllerWithIdentifier:@"CardViewController"];
         [self.navigationController pushViewController:controller animated:NO];
    }
}

- (void)pageViewController {
    self.pvc = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];

    self.pvc.view.frame = self.view.bounds;
    [self.view addSubview:self.pvc.view];
    [self.pvc setViewControllers:@[[viewControllerArray1 objectAtIndex:0]] direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:nil];
}

- (IBAction)rightButtonPressed:(id)sender {
    [self pageViewController];
    [self.pvc setViewControllers:@[[viewControllerArray1 objectAtIndex:1]] direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:nil];
}

- (IBAction)leftButtonPressed:(id)sender {
     [self pageViewController];
     [self.pvc setViewControllers:@[[viewControllerArray1 objectAtIndex:2]] direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:nil];
}

When I click on right button and came back to this view controller my start button's push view not working.

when i click for the second time self.navigationController.viewControllers = null. — Sumi, Jan 12 '17 at 07:13
Why you are using 'setViewControllers' For push use the below answer code,[self.navigationController pushViewController:yourControllerObj animated:NO] — Vineesh TP, Jan 12 '17 at 07:21
In storyBord initialize like the below image, then when push push by usig pushViewController and when back use popViewController. Don't change the NavigationController — Vineesh TP, Jan 12 '17 at 07:22
i'm using setviewcontrollers for left/right buttons.. check the above code of mine.. is that wrong — Sumi, Jan 12 '17 at 07:24
In the 'StartButtonClicked' what you are doing ? 1. Which is your rootView Controller 2. Where you are dispalying your PageViewController — Vineesh TP, Jan 12 '17 at 07:30
start is to navigate to other view controller. And pageview is for leftButton action (navigate to another view) — Sumi, Jan 12 '17 at 07:35
Are you trying to use sideMenu like facebook or other apps ? — Vineesh TP, Jan 12 '17 at 07:38
Push like this , UIPageViewController * controller = [self.storyboard instantiateViewControllerWithIdentifier:@"UIPageViewControllerIdentifier"]; [self.navigationController pushViewController:controller animated:NO]; — Vineesh TP, Jan 12 '17 at 08:45

Please check the answer . iOS - Push viewController from code and storyboard

Don't initialize Storyboard always,

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

You can set the rootViewController from the UtoryBoard itself. Set initialViewController as a UINavigationController and Set the FirstViewController as RootViewController.

Edit : For Push use the below code,

 CardViewController* controller = [storyboard instantiateViewControllerWithIdentifier:@"CardViewController"];
    [self.navigationController pushViewController:controller animated:NO];

and Back. If use the default backButton not need to write any code. If use are using custom backButton,

[self.navigationController popViewController];

Check 2 things,

Your storyboard identifier is correct.
The root view have navigation Controller.

Your StoryBoard should be like this,

In 'StartButtonClicked' you are initializing the storyBorad again. Not need to set storyBoard again. Set via main.storyBoard itself. – Vineesh TP Jan 12 '17 at 05:13
now i removed that line.. click on left/right button and navigate to other view controller and then click back button from that view and come back here (start button not working but left/right button working).. this is the scenario. – Sumi Jan 12 '17 at 05:14
for push use the code: CardViewController* controller = [storyboard instantiateViewControllerWithIdentifier:@"CardViewController"]; [self.navigationController pushViewController:controller animated:NO]; and for back use [self.navigationController popViewController]; – Vineesh TP Jan 12 '17 at 06:04
