我正在与火力基地进行推送通知。并且我的"didReceiveRemoteNotification"函数没有被调用

Question

我正在使用Firebase进行推送通知。 并且我的"didReceiveRemoteNotification"函数未被调用。我不知道为什么我的函数没有被调用，控制台中也没有收到有效负载数据。请解决我的问题。提前谢谢。

**Here is my code:**
FirebaseApp.configure()
Messaging.messaging().shouldEstablishDirectChannel = true
// [START register_for_notifications]
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], 
categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
// [END register_for_notifications]
// Add observer for InstanceID token refresh callback.
NotificationCenter.default
.addObserver(self, selector: 
#selector(AppDelegate.tokenRefreshNotification),
name: NSNotification.Name.InstanceIDTokenRefresh, 
object: nil)
@objc func tokenRefreshNotification(_ notification: UIViewController)
{
Messaging.messaging().subscribe(toTopic: "Testing")
}
func application(_ application: UIApplication, didReceiveRemoteNotification 
userInfo: [AnyHashable : Any])
{
print("userInfo(userInfo)")
}

import UserNotifications

in didFinishLaunchingWithOptions

if #available(iOS 10, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
application.registerForRemoteNotifications()
} else {
application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
}
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()
registerForPushNotifications(application: application)

//MARK： 推送通知方法：

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

}
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print(response.notification.request.content.userInfo)
let dic = response.notification.request.content.userInfo as NSDictionary
if let aps = dic["aps"] as? [String: Any] {
print(aps)
}
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .badge, .sound])
print(notification.request.content.userInfo)
let dic = notification.request.content.userInfo as NSDictionary
if let aps = dic["aps"] as? [String: Any] {
print(aps)
}
}
func application(_ application: UIApplication, didReceiveRemoteNotification data: [AnyHashable : Any]) {
// Print notification payload data
print("Push notification received: (data)")
}

尝试使用didreceiveremotenotification completionhandler方法。不要忘记在项目设置部分的功能选项卡中启用推送通知功能。
