Ios 在Swift中加载UIView时自定义转换出错

我有一个UiViewcontroller，它有多个元素。当单击单元格上的accessoryButtonType时，它应该会打开一个带有自定义转换的窗口，但是在为转换创建代码之后，我的UIViewController根本不会加载

通过添加断点，它在我的viewDidLoad方法之后崩溃

下面是我的viewController脚本的第一部分及其viewDidLoad方法

class jeans: UIViewController, UITableViewDelegate{

@IBOutlet var insertion: UITableView!
@IBOutlet var continent: UITableView!
@IBOutlet var sizeOutputCell: UITableView!
var size = ["Size waist", "Size inseam"]
let customTransitionManager = TransitionManager()

override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor(red:(239/255.0), green:(238/255.0), blue:(243/255.0), alpha: 1.0)
    insertion.scrollEnabled = false;
    continent.scrollEnabled = false;


    let nib = UINib(nibName: "vwTableCell", bundle: nil)
    self.insertion.registerNib(nib, forCellReuseIdentifier: "customCell")
    let outputNib = UINib(nibName:"outputView", bundle:nil)
    self.sizeOutputCell.registerNib(outputNib, forCellReuseIdentifier: "outputCell")
    self.customTransitionManager.sourceViewController = self

}

这一行代码在我的

TransitionManager.Class

中突出显示（它是第128行）：

出现以下错误：

Could not cast value of type 'Converter.ViewController' (0x1000f7ce0) to 'Clothes_Converter.DetailedView' (0x1000f7f10).

这就是它所采用的方法：

func animateTransition(transitionContext: UIViewControllerContextTransitioning) {

    // get reference to our fromView, toView and the container view that we should perform the transition in
    let container = transitionContext.containerView()

    // create a tuple of our screens
    let screens : (from:UIViewController, to:UIViewController) = (transitionContext.viewControllerForKey(UITransitionContextFromViewControllerKey)!, transitionContext.viewControllerForKey(UITransitionContextToViewControllerKey)!)

    // assign references to our menu view controller and the 'bottom' view controller from the tuple
    // remember that our menuViewController will alternate between the from and to view controller depending if we're presenting or dismissing
    let menuViewController = !self.presenting ? screens.from as! DetailedView : screens.to as! DetailedView
    let topViewController = !self.presenting ? screens.to as UIViewController : screens.from as UIViewController

    let menuView = menuViewController.view
    let topView = topViewController.view

    // prepare menu items to slide in
    if (self.presenting){
        self.offStageMenuControllerInteractive(menuViewController) // offstage for interactive
    }

    // add the both views to our view controller

    container.addSubview(menuView)
    container.addSubview(topView)
    container.addSubview(self.statusBarBackground)

    let duration = self.transitionDuration(transitionContext)

    // perform the animation!
    UIView.animateWithDuration(duration, delay: 0.0, options: nil, animations: {

        if (self.presenting){
            self.onStageMenuController(menuViewController) // onstage items: slide in
            topView.transform = CGAffineTransformMakeTranslation(-container.frame.width, 0)
        }
        else {
            topView.transform = CGAffineTransformIdentity
            self.offStageMenuControllerInteractive(menuViewController)
        }

        }, completion: { finished in

            // tell our transitionContext object that we've finished animating
            if(transitionContext.transitionWasCancelled()){

                transitionContext.completeTransition(false)
                // bug: we have to manually add our 'to view' back http://openradar.appspot.com/radar?id=5320103646199808
                UIApplication.sharedApplication().keyWindow!.addSubview(screens.from.view)

            }
            else {

                transitionContext.completeTransition(true)
                // bug: we have to manually add our 'to view' back http://openradar.appspot.com/radar?id=5320103646199808
                UIApplication.sharedApplication().keyWindow!.addSubview(screens.to.view)

            }
            UIApplication.sharedApplication().keyWindow!.addSubview(self.statusBarBackground)

    })

}

我如何修复此问题，使其正常工作？我试图缩小崩溃的范围，但在viewDidLoad中添加了一个断点（在末尾），然后逐步进入所有使xCode崩溃的地方（因为它太多了），我还在每个方法之前添加了断点

如果出于任何原因需要完整的代码，可以在github~：

任何帮助都将不胜感激。

DetailedView不是一个ViewController，但您正在强制它成为一个

更改

在
中作为！详细视图
到
as？DetailedView
和其他部分都应该说明问题

这是密码
