Manually switching views in UIPageViewController causes exception

Vote count:

0

I have a UIPageViewController that displays two UIViewControllers and allows the user to swipe between the two. I implemented a button that allows the user to manually switch between the two. The code to execute this is as follows:

[self setViewControllers:@[[self.storyboard instantiateViewControllerWithIdentifier:@"PlayersViewController"]] direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:^(BOOL completion){}];

Unfortunately, every time I press the button, I get an exception that says:

* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[__NSPlaceholderArray initWithObjects:count:]: attempt to insert nil object from objects[0]'

I call the method from my custom class that extends the UIPageViewControllerDelegate.

Any help would be much appreciated!
