ios - Swift 2语法错误，方向为.Forward

我在Swift 1.2中写了下一篇:

self.pageViewController.setViewControllers(viewControllers as [AnyObject], direction: .Forward, animated: true, completion: nil)

但是现在，在Swift 2中，它会显示下一个错误:

Could not find member 'Forward'

我该如何解决？

最佳答案

您应该确保您的viewControllers不是可选的Type。如:

var viewControllers:[UIViewController] = [VC1,VC2]
self.pageViewController.setViewControllers(viewControllers, direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: nil)
