Content Page Not Right

[XuYanci]

When you swipe page forward and backward quickly , the content page will not the right index page .

I found that perhaps the setActiveContentIndex function cause the issues.

• (void)pageViewController:(UIPageViewController )pageViewController didFinishAnimating:(BOOL)finished previousViewControllers:(NSArray *)previousViewControllers transitionCompleted:(BOOL)completed
  {
  / Add this to prevent this error*/
  if (!completed) {
  return;
  }

  UIViewController *viewController = self.pageViewController.viewControllers[0];

  // Select tab
  NSUInteger index = [self indexForViewController:viewController];
  [self selectTabAtIndex:index didSwipe:YES];
  }
