Question

您好我的应用程序有问题我添加了3D Touch快速操作，我的问题是当我的应用程序不在多任务处理然后没有打开我的应用程序中的共享表有任何人一个想法我怎么能解决我的问题代码问题仅在信息视图上的共享快速操作中，问题快速操作正常工作。

// AppDelegate.swift

导入UIKit 导入MessageUI

@UIApplicationMain class AppDelegate：UIResponder，UIApplicationDelegate，MFMailComposeViewControllerDelegate {

var window: UIWindow?

enum QuickActionType : String {
    case viewControllerInfo = "com.example.infoView"
    case share = "com.example.share"
    case problem = "com.example.problem"

}

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    var QuickAction = false

    if let shortcutItem = launchOptions?[UIApplicationLaunchOptionsShortcutItemKey] as? UIApplicationShortcutItem{
        QuickAction = true
        handleQuickAction(shortcutItem)
    }

    return !QuickAction

}

func application(application: UIApplication, performActionForShortcutItem shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
    let handledQuickAction = handleQuickAction(shortcutItem)
    completionHandler(handledQuickAction)

}

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
    if error != nil {
        print(error?.localizedDescription)
    }

    self.window?.rootViewController?.dismissViewControllerAnimated(true, completion: nil)

}


func applicationWillResignActive(application: UIApplication) {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

func applicationDidEnterBackground(application: UIApplication) {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

func applicationWillEnterForeground(application: UIApplication) {
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

func applicationDidBecomeActive(application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

func applicationWillTerminate(application: UIApplication) {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

func handleQuickAction(shortcutItem: UIApplicationShortcutItem) -> Bool {

    var handled = false

    if let shortCutType = QuickActionType.init(rawValue: shortcutItem.type){
        let rootNavigationViewController = window!.rootViewController as? UINavigationController
        let rootViewController = rootNavigationViewController?.viewControllers.first as UIViewController?

        rootNavigationViewController?.popToRootViewControllerAnimated(false)

        switch shortCutType {

            // Quick Action Info

        case .viewControllerInfo:
            handled = true
            rootViewController?.performSegueWithIdentifier("infoView", sender: nil)


        case .share:
            handled = true

            let shareItems = ["hello world"]

            let activityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)

            self.window?.rootViewController?.presentViewController(activityViewController, animated: true, completion: nil)

            // Quick Action Problem

        case .problem:
            handled = true

            let mailController = MFMailComposeViewController()
            mailController.mailComposeDelegate = self
            mailController.setToRecipients(["example@gmail.com"])
            mailController.setSubject("App Bug")
            mailController.setMessageBody("(Your Problem)

            self.window?.rootViewController?.presentViewController(mailController, animated: true, completion: nil)

        }
    }

    return handled

}

}

嘿，你需要在当前的ViewController顶部显示ViewController。这是一个简单的扩展，例如在你的AppDelegate上添加它。

extension UIWindow {

func visibleViewController() -> UIViewController? {
    if let rootViewController: UIViewController  = self.rootViewController {
        return UIWindow.getVisibleViewControllerFrom(rootViewController)
    }
    return nil
}

class func getVisibleViewControllerFrom(vc:UIViewController) -> UIViewController {

    if vc.isKindOfClass(UINavigationController.self) {

        let navigationController = vc as! UINavigationController
        return UIWindow.getVisibleViewControllerFrom( navigationController.visibleViewController!)

    } else if vc.isKindOfClass(UITabBarController.self) {

        let tabBarController = vc as! UITabBarController
        return UIWindow.getVisibleViewControllerFrom(tabBarController.selectedViewController!)

    } else {

        if let presentedViewController = vc.presentedViewController {

            return UIWindow.getVisibleViewControllerFrom(presentedViewController.presentedViewController!)

        } else {

            return vc;
        }
    }
}}

现在你可以像那样检查可见的Viewcontroller

self.window?.visibleViewController()?.presentViewController(yourviewcontroller, animated: true, completion: nil)

我希望这会对你有所帮助。

应用程序关闭时，3D快速操作共享功能无效
