Removing a view controller from UIPageViewController

Question

It\'s odd that there\'s no straightforward way to do this. Consider the following scenario:

1. You have a page view controller with 1 page.
2. Add another p

Answer 1

For improve this. You should detect whether pageView is scrolling or not before setViewControllers.

var isScrolling = false

func viewDidLoad() {
...

  for v in view.subviews{
    if v.isKindOfClass(UIScrollView) {
      (v as! UIScrollView).delegate = self
    }
  }
}

func scrollViewWillBeginDragging(scrollView: UIScrollView){
    isScrolling = true
}

func scrollViewDidEndDecelerating(scrollView: UIScrollView){
    isScrolling = false
}

func jumpToVC{
    if isScrolling {  //you should not jump out when scrolling
        return
    }
    setViewControllers([vc], direction:direction, animated:true, completion:{[unowned self] (succ) -> Void in
        if succ {
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                self.setViewControllers([vc], direction:direction, animated:false, completion:nil)
            })
        }
    })
}
