我正在尝试在我的应用处于前台时显示本地通知。显示远程通知没有问题，但是当应用程序在前台运行时出现问题。我只是在使用新的 iOS 10 时遇到问题。
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
// TODO: Handle data of notification
if application.applicationState == UIApplicationState.Active {
//print("Message ID: \(userInfo["gcm.message_id"]!)")
//print("Message ID: \(userInfo.keys)")
dispatch_async(dispatch_get_main_queue(), { () -> Void in
if (userInfo["notice"] != nil) {
if #available(iOS 10.0, *) {
print ("yes")
let content = UNMutableNotificationContent()
content.title = "My Car Wash"
content.body = (userInfo["notice"] as? String)!
}
else
{
let localNotification = UILocalNotification()
localNotification.fireDate = NSDate(timeIntervalSinceNow:0)
localNotification.alertBody = userInfo["notice"] as? String
localNotification.soundName = UILocalNotificationDefaultSoundName
localNotification.alertAction = nil
localNotification.timeZone = NSTimeZone.defaultTimeZone()
UIApplication.sharedApplication().scheduleLocalNotification(localNotification)
let systemSoundID: SystemSoundID = 1000
// to play sound
AudioServicesPlaySystemSound (systemSoundID)
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
completionHandler(.NewData)
}
}
})}
}
我的 iPhone 运行的是 iOS 10，我可以看到打印出"is"。我的应用具有所需的通知权限。
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Register for remote notifications
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
// [END register_for_notifications]
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification),
name: kFIRInstanceIDTokenRefreshNotification, object: nil)
return true
}
正如在 iOS 9 设备上所提到的，代码可以正常工作，并且当应用程序未运行时我会收到通知。当应用程序处于前台时，问题出在 iOS 10 上。我已经在谷歌搜索了一段时间，但我仍然不在那里。任何帮助或建议将不胜感激。
您的代码在 iOS10 中不起作用，必须使用
UserNotifications framework
对于运行 iOS 9 及更低版本的设备，实现 AppDelegate application:didReceiveRemoteNotification: 以处理客户端应用在前台时收到的通知
对于运行 iOS 10 及更高版本的设备，实现
UNUserNotificationCenterDelegate userNotificationCenter:willPresentNotification:withCompletionHandler:
当客户端应用程序在前台时处理收到的通知(从这里 https://firebase.google.com/docs/notifications/ios/console-audience)
您的代码必须是这样的(对于 Firebase 通知):
import UIKit
import UserNotifications
import Firebase
import FirebaseInstanceID
import FirebaseMessaging
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// [START register_for_notifications]
if #available(iOS 10.0, *) {
let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound]
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
authOptions,
completionHandler: {_,_ in })
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.currentNotificationCenter().delegate = self
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
}
// [END register_for_notifications]
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self,
selector: #selector(self.tokenRefreshNotification),

object: nil)
return true
}
// [START receive_message]
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (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
// Print message ID.
print("Message ID: \(userInfo["gcm.message_id"]!)")
// Print full message.
print("%@", userInfo)
}
// [END receive_message]
// [START refresh_token]
func tokenRefreshNotification(notification: NSNotification) {
if let refreshedToken = FIRInstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
// [END refresh_token]
// [START connect_to_fcm]
func connectToFcm() {
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil) {
print("Unable to connect with FCM. \(error)")
} else {
print("Connected to FCM.")
}
}
}
// [END connect_to_fcm]
func applicationDidBecomeActive(application: UIApplication) {

}
// [START disconnect_from_fcm]
func applicationDidEnterBackground(application: UIApplication) {
FIRMessaging.messaging().disconnect()
print("Disconnected from FCM.")
}
// [END disconnect_from_fcm]
}
// [START ios_10_message_handling]
@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(center: UNUserNotificationCenter,
willPresentNotification notification: UNNotification,
withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
// Print message ID.
print("Message ID: \(userInfo["gcm.message_id"]!)")
// Print full message.
print("%@", userInfo)
}
}
extension AppDelegate : FIRMessagingDelegate {
// Receive data message on iOS 10 devices.
func applicationReceivedRemoteMessage(remoteMessage: FIRMessagingRemoteMessage) {
print("%@", remoteMessage.appData)
}
}
// [END ios_10_message_handling]
