子視圖滾動不工作SWIFT

目標：做一個視圖控制器有多個頁面，並且可以通過分段控制器進行交換，內容的網頁滾動垂直子視圖滾動不工作SWIFT

細節：

我做了一個pagviewcontroller和嵌入它作爲一個子視圖到主視圖 - 控制

//add pageviewcontroller as subview to viewcontroller 
if let vc = storyboard?.instantiateViewControllerWithIdentifier("ProfileEditController"){ 

    self.addChildViewController(vc) 
    self.view.addSubview(vc.view) 

    EditTabs = vc as! UIPageViewController 
    EditTabs.dataSource = self 
    EditTabs.delegate = self 

    //define First page 
    EditTabs.setViewControllers([pagesAtIndexPath(0)!], direction:.Forward, animated: true, completion: nil) 
    EditTabs.didMoveToParentViewController(self) 

    //bring segmented view buttons to front of pageViews 
    self.view.bringSubviewToFront(self.topTabs) 
}

我叫pageViewController功能，並且我將通過restoratio頁N個標識符

我通過獲取的PageIndex和設置視圖 - 控制這樣的管理分割視圖控制器：

EditTabs.setViewControllers([pagesAtIndexPath(0)!], direction:.Reverse, animated: true, completion: nil)

在故事板的子頁面具有內滾動視圖舉辦
我測試的內容子頁面滾動視圖通過調用它通過segue和其工作正常

案例：

一切工作的子頁面的罰款只有滾動視圖是不是在所有

工作，如何解決這個問題？您指引我將非常感激

感謝，

我已經創建了一個PageViewController視圖控制器與在它已經滾動視圖中有三個視圖控制器。它工作正常。

進口的UIKit 類的ViewController：UIViewController中，UIPageViewControllerDataSource {

var viewControllers : [UIViewController]? 
override func viewDidLoad() { 
    super.viewDidLoad() 
    CreatePageView() 
} 

func CreatePageView() { 

    SetupViewControllers() 

    let pageViewController = UIPageViewController(transitionStyle: .scroll, navigationOrientation: .horizontal, options: nil) 
    pageViewController.dataSource = self 
    pageViewController.setViewControllers([(viewControllers?[0])!] , direction: .forward, animated: false, completion: nil) 
    pageViewController.view.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height); 
    pageViewController.view.frame = CGRect(x: 0, y: 0, width: view.frame.size.width, height: view.frame.size.height); 
    addChildViewController(pageViewController) 
    view.addSubview(pageViewController.view) 
    pageViewController.didMove(toParentViewController: self) 
    pageViewController.view.backgroundColor = UIColor.blue 
} 

func SetupViewControllers() { 
    let firstVC = UIViewController() 
    firstVC.view.tag = 100 
    firstVC.view.backgroundColor = UIColor.red 
    AddScrollView(bgView: firstVC.view) 
    let secondVC = UIViewController() 
    secondVC.view.tag = 101 
    secondVC.view.backgroundColor = UIColor.brown 
    AddScrollView(bgView: secondVC.view) 
    let thirdVC = UIViewController() 
    thirdVC.view.tag = 102 
    thirdVC.view.backgroundColor = UIColor.purple 
    AddScrollView(bgView: thirdVC.view) 

    viewControllers = [firstVC,secondVC,thirdVC] 

} 

func AddScrollView(bgView: UIView) { 
    let scrollView = UIScrollView() 
    scrollView.frame = CGRect.init(x: 10, y: 10, width: bgView.frame.width-20, height: bgView.frame.height-20) 
    scrollView.backgroundColor = UIColor.init(red: 0.34, green: 0.45, blue: 0.35, alpha: 0.9) 
    bgView.addSubview(scrollView) 
    scrollView.contentSize = CGSize.init(width: scrollView.frame.size.width, height: scrollView.frame.size.height+200) 
} 


func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? { 
    if viewController.view.tag == 101 { 
     return viewControllers?[0] 
    } 
    else if viewController.view.tag == 102{ 
     return viewControllers?[1] 
    } 
    else{ 
     return viewControllers?[2] 
    } 
} 

public func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? { 
    if viewController.view.tag == 101 { 
     return viewControllers?[0] 
    } 
    else if viewController.view.tag == 102{ 
     return viewControllers?[1] 
    } 
    else{ 
     return viewControllers?[2] 
    } 
} 

func presentationCount(for pageViewController: UIPageViewController) -> Int { 
    return (viewControllers?.count)! 
} 

func presentationIndex(for pageViewController: UIPageViewController) -> Int { 
    return 0 
}

}

類似問題相當頻繁的堆棧提高。對於我自己的問題，在非常相似的情況下，我也可以在它自己的視圖中使用scrollview而不會出現問題，但是當在另一個子視圖中用作子視圖時，我需要以編程方式設置scrollview尺寸。

夫特2

scrollView.setFrame(CGRectMake(0, 0, DEVICE_WIDTH, DEVICE_HEIGHT))

或

夫特3

scrollView.setFrame(CGRect(x: 0, y: 0, width: DEVICE_WIDTH, height: DEVICE_HEIGHT))

另一個（並且通常被視爲一個更好的）建議，自動設定小號根據內容進行分類。

var contentRect = CGRectZero 
for view in self.scrollView.subviews { 
    contentRect = CGRectUnion(contentRect, view.frame) 
} 
self.scrollView.contentSize = contentRect.size

希望這會有所幫助。
