didRegisterForRemoteNotificationsWithDeviceToken 未在 ios 10 上调用

Question

我已经在 appDelegate 中编写了这段代码

import UserNotifications
var registerId = String()
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    self.registerForPushNotifications(application)
    return true   
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    let tokenChars = UnsafePointer<CChar>(deviceToken.bytes)
    var tokenString = ""
    for i in 0..<deviceToken.length {
        tokenString += String(format: "%02.2hhx", arguments: [tokenChars[i]])
    }
    registerId = tokenString
}
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
    if notificationSettings.types != .None {
        application.registerForRemoteNotifications()
    }
}
func registerForPushNotifications(application: UIApplication) {

    if #available(iOS 10.0, *){
        UNUserNotificationCenter.currentNotificationCenter().delegate = self
        UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert], completionHandler: {(granted, error) in
            if (granted)
            {
               application.registerForRemoteNotifications()
            }
            else{
                registerId = "111111"
                //Do stuff if unsuccessful...
            }
        })
    }

    else{
        let notificationSettings = UIUserNotificationSettings(
            forTypes: [.Badge, .Sound, .Alert], categories: nil)
        application.registerUserNotificationSettings(notificationSettings)

    }

}
}

使用此代码，我可以在 ios 版本 < 10 中获取设备令牌，但对于 ios 10 及更高版本，不会调用 didRegisterForRemoteNotificationsWithDeviceToken。 任何帮助表示赞赏

最后一件事，添加框架：

import UserNotifications

class AppDelegate: /*Some other protocols I am extending...*/, UNUserNotificationCenterDelegate {

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
...
    registerForPushNotifications(application)
...
}


    func registerForPushNotifications(application: UIApplication) {

    if #available(iOS 10.0, *){
        UNUserNotificationCenter.current().delegate = self
        UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(granted, error) in
            if (granted)
            {
                UIApplication.shared.registerForRemoteNotifications()
            }
            else{
                //Do stuff if unsuccessful...
            }
        })
    }
    else { //If user is not on iOS 10 use the old methods we've been using
        let notificationSettings = UIUserNotificationSettings(
            types: [.badge, .sound, .alert], categories: nil)
        application.registerUserNotificationSettings(notificationSettings)

    }

}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {

 }
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    //Handle the notification
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    //Handle the notification
}

}

除了所有这些，您还必须启用来自功能的推送通知。

单击您的项目目标，您将看到屏幕和启用推送通知的功能。

将此用于 ios 10 -

func registerForPushNotifications(_ application: UIApplication) {
      let notificationSettings = UIUserNotificationSettings(
                types: [.badge, .sound, .alert], categories: nil)
            application.registerUserNotificationSettings(notificationSettings)
}
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
      if notificationSettings.types != UIUserNotificationType() {
                application.registerForRemoteNotifications()
      }
}
func application( _ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data ) {

       var token: String = ""
       for i in 0..<deviceToken.count {
           token += String(format: "%02.2hhx", deviceToken[i] as CVarArg)
       }

       UserDefaults.standard.setValue(token, forKey: "kDeviceToken")
       UserDefaults.standard.synchronize()
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {}

PS：- 创建适当的证书和捆绑 ID 也。按照本教程 - https://www.raywenderlich.com/123862/push-notifications-tutorial

使用 //Register 推送通知

registerForPushNotifications(application)

在didFinishLaunchingWithOptions方法中
