- (void)viewDidLoad

{

PagedImageScrollView *pageScrollView = [[PagedImageScrollView alloc] initWithFrame:CGRectMake(0, 32, 320, 165)];

[pageScrollView setScrollViewContents:@[[UIImage imageNamed:@"slider1"], [UIImage imageNamed:@"slider2"],[UIImage imageNamed:@"slider3"]]];

pageScrollView.pageControlPos = PageControlPositionCenterBottom;

[self.view addSubview:pageScrollView];

pageScrollView.delegate1 = self;

self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];

self.pageViewController.dataSource = self;

PageContentViewController *startingViewController = [self secondviewcontrollerAtIndex:0];

//secondviewcontroller *startingViewController = [self secondviewcontrollerAtIndex:0];

//

NSArray *viewControllers = @[startingViewController];

[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

// PageContentViewController2 *startingViewController2 = [self secondviewcontrollerAtIndex:0];

//

// NSArray *viewControllers2 = @[startingViewController2];

//

//

// [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

// [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

//

// Change the size of page view controller

self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height + 40);

[self addChildViewController:_pageViewController];

[self.view addSubview:_pageViewController.view];
