Swift 使用ApplicationShortCut SIGTRAP时崩溃

当我试图使用

ApplicationshortcutItem

导航到视图控制器时，我的应用程序立即崩溃。 但是，我的另一个应用程序快捷方式（位于1

viewcontroller

more中）没有显示这种行为。 导航到同一视图控制器可以工作，但不会使其崩溃

我的崩溃：

方法，以显示视图控制器：

if let rootViewController = window?.rootViewController, let shortcutItemType = DGShortcutItemType(shortcutItem: shortcutItem) {
            rootViewController.dismissViewControllerAnimated(false, completion: nil)
            switch shortcutItemType {
            case .Message:
                let storyboard = UIStoryboard(name: "Main", bundle: nil)
                let rootTabbarController = self.window?.rootViewController as! UITabBarController
                let firstNav = storyboard.instantiateViewControllerWithIdentifier("NavController") as! UINavigationController
                rootTabbarController.viewControllers![0] = firstNav
                let VC1 = storyboard.instantiateViewControllerWithIdentifier("PeriodeView")
                let VC2 = storyboard.instantiateViewControllerWithIdentifier("weekViewController")
                let VC3 = storyboard.instantiateViewControllerWithIdentifier("timesInsertViewController")
                firstNav.viewControllers.insert(VC1, atIndex: 1)
                firstNav.viewControllers.insert(VC2, atIndex: 2)
                firstNav.pushViewController(VC3, animated: false)
                break
            case .Time:
                let storyboard = UIStoryboard(name: "Main", bundle: nil)
                let rootTabbarController = self.window?.rootViewController as! UITabBarController
                let firstNav = storyboard.instantiateViewControllerWithIdentifier("NavController") as! UINavigationController
                rootTabbarController.viewControllers![0] = firstNav
                let VC1 = storyboard.instantiateViewControllerWithIdentifier("PeriodeView")
                let VC2 = storyboard.instantiateViewControllerWithIdentifier("weekViewController")
                firstNav.viewControllers.insert(VC1, atIndex: 1)
                firstNav.pushViewController(VC2, animated: false)

                // Display an alert indicating the shortcut selected from the home screen.
                break
            }
        }

注意

case.Time

正在被调用

该视图显示tableview，并使用全局变量“pressedYear”，该变量在导航到viewController之前在viewController上设置。 我的应用程序委托也设置了这个非常相同的变量

如何解决此问题？由于我无法清楚地看到哪里出了问题，我已经能够确定问题所在。 由于我以前没有访问控制台的权限（不得不终止应用程序），因此我更改了方案，并确保在UIApplicationShortcut上首次启动应用程序时，我确实有访问调试工具的权限

我做了以下工作： 我选择了我的设备并单击了“编辑方案”

这将向您显示以下结果：

如果你按下“等待可执行文件被启动”，你可以完全关闭应用程序，只需在安装了调试器的情况下运行它

原来我的应用程序被卡住了，因为设置了一个变量，然后神奇地设置为

”

，这使得应用程序崩溃，因为它无法将

“

转换为

Int

。 我将不得不研究这个问题，但不是为了。它是固定的
