UIPageViewController - how Can I jump to a particular page number?

Question

I have spent almost 8 hours finding out how to jump to a particular page number in UIPageViewController... below is what my project looks like

I want to make an app

Answer 1

I use this function (I'm always in landscape, 2 page mode)

-(void) flipToPage:(NSString * )index {


int x = [index intValue];
LeafletPageContentViewController *theCurrentViewController = [self.pageViewController.viewControllers   objectAtIndex:0];

NSUInteger retreivedIndex = [self indexOfViewController:theCurrentViewController];

LeafletPageContentViewController *firstViewController = [self viewControllerAtIndex:x];
LeafletPageContentViewController *secondViewController = [self viewControllerAtIndex:x+1 ];


NSArray *viewControllers = nil;

viewControllers = [NSArray arrayWithObjects:firstViewController, secondViewController, nil];


if (retreivedIndex < x){

    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

} else {

    if (retreivedIndex > x ){

        [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:NULL];
      } 
    }
} 

Maybe you need this too

- (LeafletPageContentViewController *)viewControllerAtIndex:(NSUInteger)index {   

    if (([self.modelArray count] == 0) || (index >= [self.modelArray count])) {
        return nil;
    }
    LeafletPageContentViewController *dataViewController;
    dataViewController = [[LeafletPageContentViewController alloc]initWithNibName:@"LeafletPageContentViewController" bundle:nil];

    dataViewController.dataObject = [self.modelArray objectAtIndex:index];
    return dataViewController;

}
