我正在尝试在SwiftUI 2.0中实现远程推送通知,并且没有AppDelegate。我知道我可以提供一个,@UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
但我不建议这样做。
我尝试通过Firebase Cloud Messaging触发通知,但没有收到任何测试通知。我刚弹出允许通知的窗口,仅此而已。
我没有收到任何错误或其他任何信息。
我想念什么吗?
考试:
Firebase registration token: Optional("fwRsIKd7aUZeoLmmW5b4Zo:APA91bHrVvArS-mLZMEkdtzTxhRUuMWVgHNKXdLethAvR3Fa3h_RmAcdOz_jJzp1kDsEEtcvbnAFUn9eh9-cUSCTy9jBibbFoR2xngWdzWCvci1_iLQJtHtCjxk-C02CkVUDl7FX8esp")
这是我的代码:
import SwiftUI
import Firebase
import OSLog
@main
struct Le_fretApp: App {
@StateObject var sessionStore = SessionStore()
@StateObject var locationManagerService = LocationManagerService()
@StateObject var userViewModel = UserViewModel()
var notificationsService = NotificationsService()
init() {
UIApplication.shared.delegate = NotificationsService.Shared
FirebaseConfiguration.shared.setLoggerLevel(.min)
notificationsService.register()
FirebaseApp.configure()
notificationsService.setDelegate()
}
var body: some Scene {
WindowGroup {
TabViewContainerView()
.environmentObject(sessionStore)
.environmentObject(userViewModel)
.environmentObject(locationManagerService)
.onAppear {
sessionStore.listen()
userViewModel.listen()
}
}
}
}

我刚刚创建了一个App Delegate
。适用于本地和远程通知。
我有一个PushNotificationManager
做远程推送。每当我将数据发送到Firebase时(我正在使用Firestore),我都会将传递AppDelegate.fcmToken
给用户的fcmToken属性(模型中的每个用户都有一个),例如token: user.fcmToken
。
class AppDelegate: NSObject, UIApplicationDelegate {
private var gcmMessageIDKey = "gcm_message_idKey"
static var fcmToken = String()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
FirebaseApp.configure()
Messaging.messaging().delegate = self
UNUserNotificationCenter.current().delegate = self
registerForPushNotifications()
return true
}
func registerForPushNotifications() {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { [weak self] granted, _ in
print("Permission granted: \(granted)")
guard granted else { return }
self?.getNotificationSettings()
}
}
func getNotificationSettings() {
UNUserNotificationCenter.current().getNotificationSettings { settings in
print("Notification settings: \(settings)")
guard settings.authorizationStatus == .authorized else { return }
DispatchQueue.main.async {
UIApplication.shared.registerForRemoteNotifications()
}
}
}
func application(
_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
AppDelegate.fcmToken = deviceToken.hexString
}
func application(
_ application: UIApplication,
didFailToRegisterForRemoteNotificationsWithError error: Error
) {
print("Failed to register: \(error.localizedDescription)")
}
func application(
_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
print(userInfo)
completionHandler(.newData)
}
}
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
func userNotificationCenter(
_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
print("Will Present User Info: \(userInfo)")
completionHandler([[.banner, .sound]])
}
func userNotificationCenter(
_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
if response.actionIdentifier == "accept" {
print("Did Receive User Info: \(userInfo)")
completionHandler()
}
}
}
extension AppDelegate: MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
let dataDict: [String: String] = [AppDelegate.fcmToken: fcmToken ?? ""]
NotificationCenter.default.post(name: NSNotification.Name("FCMToken"), object: nil, userInfo: dataDict)
// Note: This callback is fired at each app startup and whenever a new token is generated.
AppDelegate.fcmToken = fcmToken!
}
}
extension Data {
var hexString: String {
let hexString = map { String(format: "%02.2hhx", $0) }.joined()
return hexString
}
}
它起作用了,但是在模拟器中却没有。.你知道为什么吗?
@Rexhin我不知道。您可以在模拟器上进行本地通知,甚至可以将通知从模拟器发送到设备。但是模拟器无法从您的设备接收通知。当我需要测试某些东西时,我告诉有我的应用程序的朋友我需要确认这一点。
