页面视图控制器不转换它的编码风格

你好新来swift/iphone开发，任何意见表示赞赏！页面视图控制器不转换它的编码风格

制作由3页，但是使用.pageTurn风格 - 当过渡样式设置在我的代码.scroll视图控制器过渡一个简单的基于网页的应用程序

让的PageController =视图控制器（transitionStyle： .scroll，navigationOrientation：.horizontal，options：nil）

非常困惑为什么过渡样式不符合我编码的内容？

全码：

let pageController = ViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil) 

class ViewController: UIPageViewController { 

// page view controllers here 
let cardsVC: UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "CardsNavController") 
let profileVC: UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ProfileNavController") 
let matchesVC: UIViewController! = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MatchesNavController") 

override func viewDidLoad() { 
    super.viewDidLoad() 

    view.backgroundColor = UIColor.white 
    dataSource = self 
    // loads first view 
    setViewControllers([profileVC], direction: .forward, animated: true, completion: nil) 
} 


// load left view 
func goToNextVC() { 
    let nextVC = pageViewController(self, viewControllerAfter: viewControllers![0])! 
    setViewControllers([nextVC], direction: .forward, animated: true, completion: nil) 
} 
// load right view 
func goToPreviousVC() { 
    let previousVC = pageViewController(self, viewControllerBefore: viewControllers![0])! 
    setViewControllers([previousVC], direction: .reverse, animated: true, completion: nil) 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
    } 


} 

// MARK - UIPageViewControllerDataSource 
extension ViewController: UIPageViewControllerDataSource { 

func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? { 

    // navigate right 
    switch viewController { 
    case cardsVC: 
     return profileVC 
    case profileVC: 
     return nil 
    case matchesVC: 
     return cardsVC 
    default: 
     return nil 
    } 
} 

// navigate left 
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? { 

    switch viewController { 
    case cardsVC: 
     return matchesVC 
    case profileVC: 
     return cardsVC 
    case matchesVC: 
     return nil 
    default: 
     return nil 
    } 
}

}

使用这样的：

required init?(coder: NSCoder) { 
    super.init(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil) 
}

看一看以下的项目，它会给你期望的结果我曾在这里使用的containerView要使用pageViewController为ViewControllers显示tableViews
