Question

使用Xcode 7.3我为iPad布局添加了第二个故事板（到我的通用应用程序）。除定制segues外，一切正常。对于Main.storyboard，自定义segue工作正常，但如果我运行Main~iPad.storyboard（iPad设备或iPad模拟器），segue会崩溃。崩溃报告如下：

2016-07-05 11:27:13.900 Quiz Maker[1354:42875] *** Assertion failure in -[UIStoryboardSegueTemplate segueWithDestinationViewController:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit_Sim/UIKit-3512.60.7/UIStoryboardSegueTemplate.m:85

2016-07-05 11：27：13.926 Quiz Maker [1354：42875] ***由于未捕获的异常终止应用程序＆＃39; NSInternalInconsistencyException＆＃39;，原因：＆＃39;无法创建一个segue class＆＃39;（null）＆＃39;＆＃39;

继承我的自定义segue代码：

import UIKit

class CustomRightSegue: UIStoryboardSegue
 {
override func perform()
{


    let firstClassView = self.sourceViewController.view
    let secondClassView = self.destinationViewController.view

    let screenWidth = UIScreen.mainScreen().bounds.size.width
    let screenHeight = UIScreen.mainScreen().bounds.size.height

    secondClassView.frame = CGRectMake( screenWidth, 0, screenWidth, screenHeight)

    if let window = UIApplication.sharedApplication().keyWindow {

        window.insertSubview(secondClassView, aboveSubview: firstClassView)

        UIView.animateWithDuration(0.4, animations: { () -> Void in

            firstClassView.frame = CGRectOffset(firstClassView.frame, -screenWidth, 0)
            secondClassView.frame = CGRectOffset(secondClassView.frame, -screenWidth, 0)

            }) {(Finished) -> Void in

                self.sourceViewController.navigationController?.pushViewController(self.destinationViewController, animated: false)

        }
    }

}

}

Answer 1

将自定义Segue添加为Storyboard中两个ViewControllers之间的连接。

在那里，在Attributes Inspector中选择'Module'的可用选项：
