ios - Firebase 消息传递方法 swizzling 不起作用
<p><p>您好，我正在实现 FCM(Fire base 云消息传递)。我已经让应用程序从 FCM 控制台接收通知和数据。我有我的服务器通知和 Firebase 通知。我想分别处理两种类型的通知(来 self 的服务器和来自 FCM)。我已经浏览了文档，这可以通过在 AppDelegate 中调整通知处理程序来实现</p>
<p>但问题是我只能在</p>中获取FCM消息数据(IOS 10)
<pre><code>-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {}
</code></pre>
<p>和</p>
<pre><code>-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {}
</code></pre>
<p>FCM 委托(delegate)的回调</p>
<pre><code>// The callback to handle data message received via FCM for devices running iOS 10 or above.
- (void)applicationReceivedRemoteMessage:(nonnull FIRMessagingRemoteMessage *)remoteMessage {
// Print full message
NSLog(@"Can get here firebase?%@", );
}
</code></pre>
<p>上面的回调永远不会被调用</p>
<p>我们如何使用 swizzling 单独设置 FCM 处理程序消息？</p>
<p>这是我的 Appdelegate didfinishlaunchingwith 选项</p>
<pre><code> application.applicationIconBadgeNumber = 0;
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_9_x_Max) {
UIUserNotificationType allNotificationTypes =
(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
UIUserNotificationSettings *settings =
;
[ registerUserNotificationSettings:settings];
} else {
// iOS 10 or later
#if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
UNAuthorizationOptions authOptions =
UNAuthorizationOptionAlert
| UNAuthorizationOptionSound
| UNAuthorizationOptionBadge;
[
requestAuthorizationWithOptions:authOptions
completionHandler:^(BOOL granted, NSError * _Nullable error) {
}
];
// For iOS 10 display notification (sent via APNS)
[ setDelegate:self];
// For iOS 10 data message (sent via FCM)
[ setRemoteMessageDelegate:self];
#endif
}
[ registerForRemoteNotifications];
//
;
//
// Add observer for InstanceID token refresh callback.
[ addObserver:self selector:@selector(tokenRefreshNotification:)
name:kFIRInstanceIDTokenRefreshNotification object:nil];
self.window = [ initWithFrame:[ bounds]];
self.window.backgroundColor = ;
_rootViewController = [ initWithNibName:nil bundle:nil];
;
;
NSDictionary *remoteNotification = ;
if (remoteNotification)
;
self.isFirstTime = true;
self.isJustForRefresh = 0;
return YES;
</code></pre>
<p>有人知道如何让它工作吗？</p>
<p>编辑:这是我的观察者观察函数和didregisterRemoteNotification函数</p>
<pre><code>//
- (void)tokenRefreshNotification:(NSNotification *)notification {
// Note that this callback will be fired everytime a new token is generated, including the first
// time. So if you need to retrieve the token as soon as it is available this is where that
// should be done.
NSString *refreshedToken = [ token];
NSLog(@"InstanceID token: %@", refreshedToken);
// Connect to FCM since connection may have failed when attempted before having a token.
;
// TODO: If necessary send token to application server.
}
//
//
- (void)connectToFcm {
[ connectWithCompletion:^(NSError * _Nullable error) {
if (error != nil) {
NSLog(@"Unable to connect to FCM. %@", error);
} else {
NSLog(@"Connected to FCM.");
}
}];
}
//
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken {
NSString *sanitizedDeviceToken = [[[
stringByReplacingOccurrencesOfString:@"<" withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""]
stringByReplacingOccurrencesOfString:@" " withString:@""];
DLog(@"sanitized device token: %@", sanitizedDeviceToken);
[PushNotificationManager API_registerAPNSToken:sanitizedDeviceToken
onCompletion:^(BOOL success, NSError *error){}];
[setAPNSToken:deviceToken type:FIRInstanceIDAPNSTokenTypeSandbox];
}
</code></pre>
<p>更新:我已包含此功能但仍无法正常工作</p>
<pre><code>-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{
if (userInfo[@"gcm.message_id"] != nil) {
NSLog(@"Should get here FCM?");
[appDidReceiveMessage:userInfo];
}else {
NSLog(@"test fetchCompletion handler: %@",userInfo.description);
}
}
</code></pre></p>

<p><p>你可以看看这个答案吗？好像你错过了 <code>FIRMessaging.messaging().connect(){....</code></p> 行

<p>还有委托(delegate)函数..</p>
<pre><code>func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: ,
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
// Print message ID.
print("Message ID: \(userInfo["gcm.message_id"]!)")
// Print full message.
print(userInfo)
FIRMessaging.messaging().appDidReceiveMessage(userInfo)
</code></pre>
