我在local Notifications中开发了iOS 10。运行良好。但是现在如果用户使用的是local notifications及更高版本,我应该如何编码push notificationiOS 9。有人可以帮忙吗?

下面是iOS 10中的代码

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)
        }

     }

 }

最佳答案

IOS 12 :-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有效载荷中传递thread-id
{
 "aps" : {
     "alert" : {
         "title" : "Group Notifications",
         "body" : "Body of notification"
     }
     "thread-id" : "group-identifire"
 }
}

IOS 11 :-您也可以在iOS 11上使用以下代码。推送和本地通知中无需进行任何更改

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) {

}

UNUserNotificationCenter删除

仅在ios 10及更高版本中可用

仅当应用程序在前台时,才会在委托(delegate)上调用该方法

您可以在以下方法的帮助下显示默认横幅
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    completionHandler([.badge,.alert,.sound])
}

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(delegate)上调用该方法。
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

}
