I've been trying to use the UIPageViewController to display 3 different nibs for a few days on and off now and have almost got it working. I still have one weird bug that I cant figure out.

Basically the app starts, I can scroll between the 3 pages one after another with out any problems, eg:

Page1->Page2->Page3

and then back to the start:

Page3->Page2->Page1.

No Problems. The issue is that if I scroll, for example from Page3->Page2, then BACK to Page3, Page3 Dissappears when it snaps into place. If I scroll to where a forth page would be, then I get Page3. Here is the code relevant to the UIPageViewController, the nibs and the delegate methods for the UIPageViewController:

- (void)viewDidLoad{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];

    self.pageViewController.delegate = self;
    [[self.pageViewController view] setFrame:[[self view] bounds]];

    indexTest = 0;

    Page1 *p1 = [[Page1 alloc]initWithNibName:@"Page1" bundle:nil];
    p1.view.tag = 1;

    Page2 *p2 = [[Page2 alloc]initWithNibName:@"Page2" bundle:nil];
    p2.view.tag = 2;

    Page3 *p3 = [[Page3 alloc]initWithNibName:@"Page3" bundle:nil];
    p3.view.tag = 3;

    NSArray *arr = [[NSArray alloc] initWithObjects:p1,nil];
    viewControllers = [[NSMutableArray alloc] initWithObjects:p1,p2,p3, nil];

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

    self.pageViewController.dataSource = self;

    [self addChildViewController:self.pageViewController];
    [[self view] addSubview:[self.pageViewController view]];
    [self.pageViewController didMoveToParentViewController:self];

    self.view.gestureRecognizers = self.pageViewController.gestureRecognizers;
}


#pragma mark - page view controller stuff
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController {

    if (indexTest > 0) {
        switch (indexTest) {

            case 1:{
                NSLog(@"NO page is BEFORE current page");
                break;
            }
            case 2:{
                NSLog(@"Page BEFORE is Page: %@", [NSString stringWithFormat:@"%@",[viewControllers objectAtIndex:0] ] );
                indexTest--;
                return [viewControllers objectAtIndex:0];
                break;
            }
            default:{
                NSLog(@"PROBLEM  in viewBEFORE, indexTest = %d!!!!", indexTest);
                break;
            }
        }

   }
    return nil;
}



- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController {

    if (indexTest < NUM_OF_PAGES) {
        switch (indexTest) {

            case 0:{
                NSLog(@"Page AFTER is Page: %@", [NSString stringWithFormat:@"%@",[viewControllers objectAtIndex:1] ] );
                indexTest++;
                return [viewControllers objectAtIndex:1];
                break;
            }
            case 1:{
                NSLog(@"Page AFTER is Page: %@", [NSString stringWithFormat:@"%@",[viewControllers objectAtIndex:2] ] );
                indexTest++;
                return [viewControllers objectAtIndex:2];
                break;
            }
            case 2:{
                NSLog(@"No pages AFTER this current page %d", indexTest);
                break;
            }
            default:{
                NSLog(@"PROBLEM  in viewAFTER, indexTest = %d!!!!", indexTest);
                break;
            }
        }

    }
    return nil;

}

Finally the page index dots code

#pragma mark - dot controller
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {
    // The number of items reflected in the page indicator.
    return NUM_OF_PAGES;
}

- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {
    // The selected item reflected in the page indicator.
    return 0;
}

Any and all help is much appreciated, I think I'm just doing something silly that I cant see as I'm so close to it fully working. If anythings not clear or I haven't give enough information please let me know and I'll answer it as best as I can.

Thanks
