Yes it is possible with the method:

<pre><code>- (void)setViewControllers:(NSArray *)viewControllers 
 direction:(UIPageViewControllerNavigationDirection)direction 
 animated:(BOOL)animated 
 completion:(void (^)(BOOL finished))completion;`
</code></pre>

That is the same method used for setting up the first view controller on the page. Similar, you can use it to go to other pages.

Wonder why <code>viewControllers</code> is an array, and not a single view controller?

That's because a page view controller could have a "spine" (like in iBooks), displaying 2 pages of content at a time. If you display 1 page of content at a time, then just pass in a 1-element array.

An example in Swift:

<pre><code>pageContainer.setViewControllers([displayThisViewController], direction: .Forward, animated: true, completion: nil)
</code></pre>

This code worked nicely for me, thanks. 

This is what i did with it. Some methods for stepping forward or backwards and one for going directly to a particular page. Its for a 6 page document in portrait view. It will work ok if you paste it into the implementation of the RootController of the pageViewController template.

<pre><code>-(IBAction)pageGoto:(id)sender {

 //get page to go to
 NSUInteger pageToGoTo = 4;

 //get current index of current page
 DataViewController *theCurrentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
 NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

 //get the page(s) to go to
 DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(pageToGoTo - 1) storyboard:self.storyboard];

 DataViewController *secondPageViewController = [self.modelController viewControllerAtIndex:(pageToGoTo) storyboard:self.storyboard];

 //put it(or them if in landscape view) in an array
 NSArray *theViewControllers = nil; 
 theViewControllers = [NSArray arrayWithObjects:targetPageViewController, secondPageViewController, nil];


 //check which direction to animate page turn then turn page accordingly
 if (retreivedIndex &lt; (pageToGoTo - 1) &amp;&amp; retreivedIndex != (pageToGoTo - 1)){
 [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
 }

 if (retreivedIndex &gt; (pageToGoTo - 1) &amp;&amp; retreivedIndex != (pageToGoTo - 1)){
 [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:NULL];
 }

}


-(IBAction)pageFoward:(id)sender {

 //get current index of current page
 DataViewController *theCurrentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
 NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

 //check that current page isn't first page
 if (retreivedIndex &lt; 5){

 //get the page to go to
 DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(retreivedIndex + 1) storyboard:self.storyboard];

 //put it(or them if in landscape view) in an array
 NSArray *theViewControllers = nil; 
 theViewControllers = [NSArray arrayWithObjects:targetPageViewController, nil];

 //add page view
 [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

 }

}

blocks|key|582302|text|但是，使用此“self.pageViewController+setViewControllers”方法调用不会在已翻页的页面的viewController上调用“viewDidDissapear”，而手动翻页则会在翻页的页上调用viewDidDissapear。我相信这就是我坠毁的原因|type|unstyled|depth|inlineStyleRanges|entityRanges|data|582303|“提供的视图控制器数量(0)与请求的转换所需的数量(1)不匹配”|582304|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

However using this 'self.pageViewController setViewControllers' method call does not call 'viewDidDissapear' on the viewController for the page that has been turned away, whereas manually turning a page does call viewDidDissapear on the turned away page. I believe this is the cause of my crash 

"The number of view controllers provided (0) doesn't match the number required (1) for the requested transition"

blocks|key|798352|text|正如@samwize指出的那样，分页的方法是使用|type|unstyled|depth|inlineStyleRanges|entityRanges|data|798353|setViewControllers:array|code-block|syntax|javascript|798354|我是这样做的:我把我的数据源和委托分开了。您可以调用此方法，并且只更改"next“视图。以前，您必须应用分页规则。也就是说，你必须检查方向和下一个控制器。如果将该方法用于自定义数据源，则显示的控制器数组将不会更改(因为您将在NSObject子类上使用自定义数组)。|798355|使用您自己的数据源，该方法只设置一个新视图(具有特定方向)。因为您仍将控制正常滑动时将显示的页面。|798356|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

As @samwize pointed out, the way of paginating is by using

<pre><code>setViewControllers:array
</code></pre>

Here's the way I did it:
I have my datasource and the delegate separate. You can call this method and only change the "next" view. Previously you have to apply the paging rules. 
That is, you have to check direction and the next controller. If you use that method with your custom datasource the array of controllers that you're displaying won't change (since you'll use a custom array on a NSObject subclass).

Using your own datasource the method just sets a new view (with specific direction). Since you will still controll the pages that will display when normally swiping.

blocks|key|798418|text|如果使用dataSource中的方法呢？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|798419|UIViewController+*controller+=+[pageViewController.dataSource+pageViewController:self.pageViewController+viewControllerAfterViewController:pageViewController.viewControllers.firstObject];

Analogically for backward.

I could totally be missing something here, but this solution seems a lot simpler than many others proposed.
