Question

我正在开发Swift中的iOS应用程序。

抱歉，我的英语非常糟糕。

我想在UILocalNotification上执行任何操作，设备上的fireDate被锁定或应用程序是后台。

我已经尝试将进程写入didReceiveLocalNotification。如果设备已解锁且应用程序是前台，则行为正确，但在其他情况下，它不起作用。

我该如何实施？

请帮助我！

感谢。

尝试此解决方案

在viewController.swift中查看

[查看控制器的计划Localnotification]

    func scheduleLocal() {
    let settings = UIApplication.sharedApplication(). currentUserNotificationSettings()

    if settings!.types == .None {
        let ac = UIAlertController(title: "Can't schedule", message: "Either we don't have permission to schedule notifications, or we haven't asked yet.", preferredStyle: .Alert)
        ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
        presentViewController(ac, animated: true, completion: nil)
        return
    }

    let notification = UILocalNotification()
    notification.fireDate = NSDate(timeIntervalSinceNow: 15)
    notification.alertBody = "Hey you! Yeah you! Swipe to unlock!"
    notification.alertAction = "be awesome!"
    notification.soundName = UILocalNotificationDefaultSoundName
    notification.userInfo = ["CustomField1": "w00t"]
    UIApplication.sharedApplication().scheduleLocalNotification(notification)
}

在ViewDidLoad（）

中

    self.scheduleLocal()

在applicationdidFinishlaunching（）

中

    let notificationSettings = UIUserNotificationSettings(forTypes:[.Alert, .Badge, .Sound]  , categories: nil)
    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)

    if let options = launchOptions {
        if let notification = options[UIApplicationLaunchOptionsLocalNotificationKey] as? UILocalNotification {
            if let userInfo = notification.userInfo {
                let customField1 = userInfo["CustomField1"] as! String
                // do something neat here
            }
        }
    }

最后在appdelegate.swift

    func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
    if let userInfo = notification.userInfo {
        let customField1 = userInfo["CustomField1"] as! String
        print("didReceiveLocalNotification: \(customField1)")
    }
}

尝试并使用xcode 7.3.1 swift 2.2

如何在UILocalNotification的fireDate上进行任何处理？
