[英]didReceiveRemoteNotification not called in foreground firebase cloud messaging for iOS
I tried to implement firebase cloud messaging on my app. 我试图在我的应用程序上实现Firebase云消息传递。
I register the notification using the following codes 我使用以下代码注册通知
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)
}
Everything works fine when the app is in the back ground, but when the app is in the foreground, didReceiveRemoteNotification is not called at all. 当应用程序位于后台时,一切正常,但是当应用程序位于前台时,根本不会调用didReceiveRemoteNotification。
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
// Print message ID.
print("please help")
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
completionHandler(.newData)
}
Anyone knows possible error with this? 有人知道这个错误吗? Thanks!
谢谢!
EDIT: I do not need to see a notification display when the app is in foreground, I merely want to handle the message from the notification 编辑:当应用程序处于前台时,我不需要看到通知显示,我只想处理通知中的消息
iOS 10.x has a new function that handles push notification when in foreground, you should implement this one: iOS 10.x具有一项新功能,可以在前台处理推送通知,您应该实现以下功能:
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler(
[UNNotificationPresentationOptions.alert,
UNNotificationPresentationOptions.sound,
UNNotificationPresentationOptions.badge])
}
Please implement below method to receive push notifications in foreground 请实施以下方法以在前台接收推送通知
For iOS10, Swift3: 对于iOS10,Swift3:
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)
{
completionHandler([.alert, .badge, .sound])
}
For iOS10, Swift 2.3: 对于iOS10,Swift 2.3:
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void)
{
//Handle the notification
completionHandler(
[UNNotificationPresentationOptions.Alert,
UNNotificationPresentationOptions.Sound,
UNNotificationPresentationOptions.Badge])
}
Try this once: 尝试一次:
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
print("Recived: \(userInfo)")
completionHandler(.NewData)
}
If you use Push Notification Firebase for IOS 10. Please add this code. 如果您将推送通知Firebase用于IOS 10,请添加此代码。 Hope to help you solve this problem :
希望能帮助您解决这个问题:
@available(iOS 10, *)
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
// Print message ID.
if let messageID = userInfo[gcmMessageIDKey] {
print("Message ID: \(messageID)")
}
// Print full message.
print(userInfo)
completionHandler([])
}
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)")
}
// Print full message.
print(userInfo)
completionHandler()
}
}
extension AppDelegate : FIRMessagingDelegate {
// Receive data message on iOS 10 devices while app is in the foreground.
func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
print(remoteMessage.appData)
}
}
