IOS 版本兼容的本地和推送通知 [英] Local and Push Notifications in IOS version compatible

问题描述

我在 iOS 10 中开发了 local Notifications.它运行良好.但是现在如果用户使用 iOS 9 及以上版本，我应该如何编码 local notification 和 push notification .有人可以帮忙吗?

I developed local Notifications in iOS 10. It is working perfectly. But now how should i code local notifications and push notification if user is using iOS 9 and above versions. Can anyone help please?

下面是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)
        }

     }

 }

推荐答案

IOS 12 :- 群组通知

设置threadIdentifier UNMutableNotificationContent 创建群组通知

创建本地通知组

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

创建远程通知组需要在payload中传递thread-id

create remote notification group need to pass thread-id in payload

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

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

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

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()
}

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

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

仅适用于 ios 10 及以上版本

Only available in ios 10 and above version

仅当应用程序在前台时才会在委托上调用该方法

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

您可以借助以下方法显示默认横幅

You can present default banner with helping of following method

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

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

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

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

}
