我已经在我的 SwiftUI 应用程序中实现了推送通知,一切似乎都运行良好。如您所知,没有 AppDelegate 但我们仍然可以使用 @UIApplicationDelegateAdaptor
.
但是我不喜欢这种方法,我想知道是否有办法在没有 AppDelegate 的情况下实现它?
class AppDelegate: NSObject, UIApplicationDelegate {
private var gcmMessageIDKey = "gcmMessageIDKey"
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
Messaging.messaging().delegate = self
// 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 })
application.registerForRemoteNotifications()
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired till the user taps on the notification launching the application.
// TODO: Handle data of notification
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
}
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter,
willPresent notification: UNNotification,
withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
// Change this to your preferred presentation option
completionHandler([[.banner, .sound]])
}
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// With swizzling disabled you must let Messaging know about the message, for Analytics
// Messaging.messaging().appDidReceiveMessage(userInfo)
// Print full message.
print(userInfo)
completionHandler()
}
}
extension AppDelegate: MessagingDelegate {
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String?) {
print("Firebase registration token: \(String(describing: fcmToken))")
let dataDict:[String: String] = ["token": fcmToken ?? ""]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
// TODO: If necessary send token to application server.
// Note: This callback is fired at each app startup and whenever a new token is generated.
// Add a new document in collection "cities"
guard let registrationToken = fcmToken else { return }
guard let uid = Auth.auth().currentUser?.uid else { return }
let db = Firestore.firestore()
db.collection("users").document(uid).updateData(["registrationToken": registrationToken]) { err in
if let err = err {
print("Error writing document: \(err)")
}
}
}
}
最佳答案
是否this link回答你的问题?引用:
You can use
@UIApplicationDelegateAdaptor
to provide anAppDelegate
:class AppDelegate: NSObject, UIApplicationDelegate { func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool { return true } } @main struct SampleApp: App { @UIApplicationDelegateAdaptor private var appDelegate: AppDelegate var body: some Scene { WindowGroup { ContentView() } } }
我只是在研究如何做到这一点,所以你可能领先于我。但看起来名字可能暗示@UIApplicationDelegateAdaptor 允许您使用在上面的代码中生成的 AppDelegate。
This other link也许解释得更好。看起来很像在SwiftUI里面使用UIKit .
