Adding UIPageViewController to subview, subview shows only the edge of theContviewview page

Question

I am trying to display the entire pageContentView file in a SubView on the root controller. I can see the pageView, but it does not automatically resize to fit the SubView, it only shows the cut-off part of the pageContentView

Here it looks like

Here it should look like

I cannot figure out how to resize the pageView so that it displays correctly in the subview.

RootViewController.h

#import <UIKit/UIKit.h>
#import "PageContentViewController.h"
@class PageContentViewController;

@interface CLDViewController : UIViewController <UIPageViewControllerDataSource>

@property (weak, nonatomic) IBOutlet UIView *subViewRoot;
- (IBAction)startWalkthrough:(id)sender;
@property (strong, nonatomic) UIPageViewController *pageViewController;
@property (strong, nonatomic) NSArray *pageTitles;
@property (strong, nonatomic) NSArray *pageImages;

@property (strong,nonatomic) PageContentViewController *bounds;
@end

ViewDidLoad and necessary methods for UIPageViewController in RootController

   - (void)viewDidLoad
 {

    [super viewDidLoad];

    _pageTitles = @[@"Over 200 Tips and Tricks", @"Discover Hidden Features", @"Bookmark Favorite Tip", @"Free Regular Update"];
    _pageImages = @[@"page1.png", @"page2.png", @"page3.png", @"page4.png"];

    // Create page view controller
    self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController"];
    self.pageViewController.dataSource = self;

    PageContentViewController *startingViewController = [self viewControllerAtIndex:0];
    NSArray *viewControllers = @[startingViewController];
    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

    //Trying to setup the pageViewContoller view to be inside the subview (subViewRoot)
    self.pageViewController.view.frame = self.subViewRoot.bounds;
    [self addChildViewController:_pageViewController];
    [self.subViewRoot addSubview:_pageViewController.view];
    [self.pageViewController didMoveToParentViewController:self];


}


    - (PageContentViewController *)viewControllerAtIndex:(NSUInteger)index
{
    if (([self.pageTitles count] == 0) || (index >= [self.pageTitles count])) {
        return nil;
    }

    // Create a new view controller and pass suitable data.
    PageContentViewController *pageContentViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageContentViewController"];
    pageContentViewController.imageFile = self.pageImages[index];
    pageContentViewController.titleText = self.pageTitles[index];
    pageContentViewController.pageIndex = index;

    return pageContentViewController;
}


- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Page View Controller Data Source



- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
{
    NSUInteger index = ((PageContentViewController*) viewController).pageIndex;

    if ((index == 0) || (index == NSNotFound)) {
        return nil;
    }

    index--;
    return [self viewControllerAtIndex:index];
}

- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
    NSUInteger index = ((PageContentViewController*) viewController).pageIndex;

    if (index == NSNotFound) {
        return nil;
    }

    index++;
    if (index == [self.pageTitles count]) {
        return nil;
    }
    return [self viewControllerAtIndex:index];
}

- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController
{
    return [self.pageTitles count];
}

- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController
{
    return 0;
}

PageContentViewController.m

-viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.backgroundImageView.image = [UIImage imageNamed:self.imageFile];
    self.titleLabl.text = self.titleText;

}

Has anyone encountered this situation before? What did you do?

Thanks for the help!
