我local Notifications在iOS 10. 它运行良好。但是现在我应该如何编码local notifications以及push notification用户是否使用iOS 9及以上版本。有人可以帮忙吗？

Below is code in iOS 10

下面是代码 iOS 10

import UIKit
import UserNotifications

@available(iOS 10.0, *)
class ViewController: UIViewController,UNUserNotificationCenterDelegate {
    override func viewDidLoad() {
       super.viewDidLoad()

       if #available(iOS 10.0, *) {
        //Seeking permission of the user to display app notifications
        UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.sound,.badge], completionHandler: {didAllow,Error in })
        UNUserNotificationCenter.current().delegate = self

       }
   }

   //To display notifications when app is running  inforeground
   func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
       completionHandler([.alert, .sound, .badge])
   }

   override func didReceiveMemoryWarning() {
       super.didReceiveMemoryWarning()
       // Dispose of any resources that can be recreated.
   }

   @IBAction func buttonPressed(_ sender: UIButton) {

       if #available(iOS 10.0, *) {

           //Setting content of the notification
           let content = UNMutableNotificationContent()
           content.title = "hello"
           content.body = "notification pooped out"
           content.badge = 1

           //Setting time for notification trigger
           let date = Date(timeIntervalSinceNow: 10)
           var dateCompenents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: date)

           let trigger = UNCalendarNotificationTrigger(dateMatching: dateCompenents, repeats: false)
           //Adding Request
           let request = UNNotificationRequest(identifier: "timerdone", content: content, trigger: trigger)
           UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
        }

     }

 }

IOS 12:- Group notification

IOS 12:- 群组通知

set threadIdentifierUNMutableNotificationContentto create group notification

设置threadIdentifierUNMutableNotificationContent为创建群组通知

create local notification group

创建本地通知组

let content = UNMutableNotificationContent()
content.title = "Group Notifications"
content.body = "Body of notification"
content.threadIdentifier = "group-identifire"

create remote notification group need to pass thread-idin payload

创建远程通知组需要传入thread-id有效载荷

{
 "aps" : {
     "alert" : {
         "title" : "Group Notifications",
         "body" : "Body of notification"
     }
     "thread-id" : "group-identifire"
 }
}

IOS 11:- You can also use following code for iOS 11. No any kind of changes requires in push and local notification

IOS 11:- 您也可以在 iOS 11 中使用以下代码。推送和本地通知不需要任何类型的更改

Creating A Notification Request

创建通知请求

import UserNotifications

if #available(iOS 10.0, *) {
    //iOS 10.0 and greater
    UNUserNotificationCenter.current().delegate = self
    UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: { granted, error in
        DispatchQueue.main.async {
            if granted {
                UIApplication.shared.registerForRemoteNotifications()
            }
            else {
                //Do stuff if unsuccessful...
            }
        }
   })
}
else { 
    //iOS 9
    let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound]
    let setting = UIUserNotificationSettings(types: type, categories: nil)
    UIApplication.shared.registerUserNotificationSettings(setting)
    UIApplication.shared.registerForRemoteNotifications()
}

Schedule Local Notification

安排本地通知

if #available(iOS 10.0, *) {
    //iOS 10 or above version
    let center = UNUserNotificationCenter.current()
    let content = UNMutableNotificationContent()
    content.title = "Late wake up call"
    content.body = "The early bird catches the worm, but the second mouse gets the cheese."
    content.categoryIdentifier = "alarm"
    content.userInfo = ["customData": "fizzbuzz"]
    content.sound = UNNotificationSound.default()

    var dateComponents = DateComponents()
    dateComponents.hour = 15
    dateComponents.minute = 49
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)

    let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
    center.add(request)
} else {
    // ios 9 
    let notification = UILocalNotification()
    notification.fireDate = NSDate(timeIntervalSinceNow: 5) as Date
    notification.alertBody = "Hey you! Yeah you! Swipe to unlock!"
    notification.alertAction = "be awesome!"
    notification.soundName = UILocalNotificationDefaultSoundName
    UIApplication.shared.scheduleLocalNotification(notification)
}

UIApplicationDelegate

UI应用程序委托

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenParts = deviceToken.map { data -> String in
        return String(format: "%02.2hhx", data)
    }
    let token = tokenParts.joined()
    print(token)
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

}

UNUserNotificationCenterDelegate

UNUserNotificationCenterDelegate

Only available in ios 10 and above version

仅适用于 ios 10 及以上版本

The method will be called on the delegate only if the application is in the foreground

仅当应用程序在前台时才会在委托上调用该方法

You can present default banner with helping of following method

您可以借助以下方法显示默认横幅

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    completionHandler([.badge,.alert,.sound])
}

The method will be called on the delegate when the user responded to the notification by opening the application, dismissing the notification or choosing a UNNotificationAction

当用户通过打开应用程序、关闭通知或选择 UNNotificationAction 响应通知时，将在委托上调用该方法

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

}

I have made this class for Swift 3which has a function for requesting permission to push notification and also a send notification. Works on for iOS 9 and iOS 10+.

我为Swift 3 创建了这个类，它具有请求推送通知和发送通知权限的功能。适用于 iOS 9 和 iOS 10+。

import UIKit
import UserNotifications

class LocalNotification: NSObject, UNUserNotificationCenterDelegate {

    class func registerForLocalNotification(on application:UIApplication) {
        if (UIApplication.instancesRespond(to: #selector(UIApplication.registerUserNotificationSettings(_:)))) {
            let notificationCategory:UIMutableUserNotificationCategory = UIMutableUserNotificationCategory()
            notificationCategory.identifier = "NOTIFICATION_CATEGORY"

            //registerting for the notification.
            application.registerUserNotificationSettings(UIUserNotificationSettings(types:[.sound, .alert, .badge], categories: nil))
        }
    }

    class func dispatchlocalNotification(with title: String, body: String, userInfo: [AnyHashable: Any]? = nil, at date:Date) {

        if #available(iOS 10.0, *) {

            let center = UNUserNotificationCenter.current()
            let content = UNMutableNotificationContent()
            content.title = title
            content.body = body
            content.categoryIdentifier = "Fechou"

            if let info = userInfo {
                content.userInfo = info
            }

            content.sound = UNNotificationSound.default()

            let comp = Calendar.current.dateComponents([.hour, .minute], from: date)

            let trigger = UNCalendarNotificationTrigger(dateMatching: comp, repeats: true)

            let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)

            center.add(request)

        } else {

            let notification = UILocalNotification()
            notification.fireDate = date
            notification.alertTitle = title
            notification.alertBody = body

            if let info = userInfo {
                notification.userInfo = info
            }

            notification.soundName = UILocalNotificationDefaultSoundName
            UIApplication.shared.scheduleLocalNotification(notification)

        }

        print("WILL DISPATCH LOCAL NOTIFICATION AT ", date)

    }
}

Usage:

用法：

You can request permission anywhere:

您可以在任何地方请求许可：

LocalNotification.registerForLocalNotification(on: UIApplication.shared)

And to dispatch a local notification:

并发送本地通知：

LocalNotification.dispatchlocalNotification(with: "Notification Title for iOS10+", body: "This is the notification body, works on all versions", at: Date().addedBy(minutes: 2))

Tip:

提示：

You can set the notification to fire at any future Date, in this example I'm using a date extension to get a future date in minutes to the notification fire. This is it:

您可以将通知设置为在未来的任何日期触发，在本例中，我使用日期扩展来获取未来通知触发的日期（以分钟为单位）。就是这个：

extension Date {
    func addedBy(minutes:Int) -> Date {
        return Calendar.current.date(byAdding: .minute, value: minutes, to: self)!
    }
}
