Ios 使用不带故事板的穿行库，穿行自定义

我正在使用图书馆进行个人演练。它的实现非常简单，但我在BWwalkthrowhViewController中有一个错误：我不会使用故事板来创建这个主控制器，所以我通过代码创建了我的自定义视图，然后在BWwalkthrowhViewController的viewDidLoad中设置了视图和页面控件。其余代码与github存储库中的示例相同

这是BWwalkthrowViewController的viewDidLoad：

override func viewDidLoad() {
    super.viewDidLoad()
    let welcomeview: WelcomeView = WelcomeView() // my custom view
    view = welcomeview
    self.pageControl = welcomeview.pageControl 
    ...
}

而且，因为它是第一个视图，所以rootViewController是使用修改了viewDidLoad的BWwalkthrowhViewController设置的。因此，我在AppDelegate.swift中有一个用于设置此演练的func：

func showWelcomeView() -> BWWalkthroughViewController{
    let storyboard = UIStoryboard(name: "Welcome", bundle: nil)

    let walkthrough: BWWalkthroughViewController = BWWalkthroughViewController()
    let page_zero = storyboard.instantiateViewControllerWithIdentifier("walk_0") as! UIViewController
    let page_one = storyboard.instantiateViewControllerWithIdentifier("walk_1") as! UIViewController
    let page_two = storyboard.instantiateViewControllerWithIdentifier("walk_2") as! UIViewController
    let page_three = storyboard.instantiateViewControllerWithIdentifier("walk_3") as! UIViewController
    let page_four = storyboard.instantiateViewControllerWithIdentifier("walk_4") as! UIViewController

    walkthrough.delegate = self
    walkthrough.addViewController(page_zero)
    walkthrough.addViewController(page_one)
    walkthrough.addViewController(page_two)
    walkthrough.addViewController(page_three)
    walkthrough.addViewController(page_four)




    return walkthrough
}

我在这里使用这个函数：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.


    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window?.rootViewController = showWelcomeView() // func usedhere
    return true
}

应用程序运行时没有错误。我可以看到我的自定义视图和所有4个子视图（walk_0…walk_4），我可以滑动它们，但不能正确滑动：可滚动视图是免费的，不会在每个页面上停止

所以。。。我在自定义视图中遗漏了一些步骤？请帮帮我

这是我的IPhone屏幕截图，滚动条位于两个子视图之间：

你连接了吗

@IBOutlet var pageControl:UIPageControl？

在BWWalkthroughViewController中，是否在视图控制器中使用页面控制器

---

我通过在BWWalkthroughViewController中使用scrollview属性修复了这个问题

override func viewDidLoad() {
    super.viewDidLoad()

   ..

    scrollview.pagingEnabled = true
}

工作很好，但不知道为什么。该滚动视图的默认值为

pagingeEnabled=true

在init中设置：

required init(coder aDecoder: NSCoder) {
    // Setup the scrollview
    scrollview = UIScrollView()
    scrollview.showsHorizontalScrollIndicator = false
    scrollview.showsVerticalScrollIndicator = false
    scrollview.pagingEnabled = true  // Default of scrollview

    // Controllers as empty array
    controllers = Array()

    super.init(coder: aDecoder)
}

在

bwalkthroughviewcontroller

类中添加以下函数

override func viewDidLayoutSubviews(){
    // Constraints
        let metricDict = ["w":view.bounds.size.width,"h":view.bounds.size.height]

        // - Generic cnst
        for vc in controllers {
            vc.view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[view(h)]", options:[], metrics: metricDict, views: ["view":vc.view]))
            vc.view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:[view(w)]", options:[], metrics: metricDict, views: ["view":vc.view]))
            scrollview.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-0-[view]|", options:[], metrics: nil, views: ["view":vc.view,]))
        }
    }

从

addViewController

函数中删除以下行

// Constraints
let metricDict = ["w":vc.view.bounds.size.width,"h":vc.view.bounds.size.height]
    // - Generic cnst
        vc.view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:[view(h)]", options:[], metrics: metricDict, views: ["view":vc.view]))
        vc.view.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:[view(w)]", options:[], metrics: metricDict, views: ["view":vc.view]))
        scrollview.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("V:|-0-[view]|", options:[], metrics: nil, views: ["view":vc.view,]))

我不能直接连接这个，因为我有我的自定义类。。。或者告诉我如何连接该^^^导航到BWWalkthroughViewController并找到我在上图中高亮显示的行。单击并拖动左侧边沟中的空点到视图控制器中的页面控制视图。@rednivlat，兄弟，你能帮我看一下我的问题吗？兄弟，你能帮我看一下我的问题吗？
