Firebase通知不触发didReceiveRemoteNotification仅触发didReceiveMessage

Question

发送通知时，只会触发didReceiveMessage方法，而不会触发didReceiveRemoteNotification。我遵循了文档和快速入门示例，但似乎不起作用。这是我的代码：

#import "AppDelegate.h"
#import "NavigationViewController.h"


@import Firebase;
@import FirebaseInstanceID;
@import UserNotifications;


@interface AppDelegate ()<UNUserNotificationCenterDelegate, FIRMessagingDelegate>
@property(nonatomic, strong) void (^registrationHandler)
(NSString *registrationToken, NSError *error);
@property(nonatomic, assign) BOOL connectedToGCM;
@property(nonatomic, strong) NSString* registrationToken;
@end


@implementation AppDelegate
NSString *const kGCMMessageIDKey = @"gcm.message_id";


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    ...

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(tokenRefreshNotification:)
                                                 name:kFIRInstanceIDTokenRefreshNotification object:nil];


    [FIRApp configure];

    [FIRMessaging messaging].delegate=self ;


    if ([UNUserNotificationCenter class] != nil) {
        // iOS 10 or later
        // For iOS 10 display notification (sent via APNS)
        [UNUserNotificationCenter currentNotificationCenter].delegate = self;
        UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert |
        UNAuthorizationOptionSound | UNAuthorizationOptionBadge;
        [[UNUserNotificationCenter currentNotificationCenter]
         requestAuthorizationWithOptions:authOptions
         completionHandler:^(BOOL granted, NSError * _Nullable error) {
             // ...
             NSLog(@"notif request granted:%@",granted?@"YES":@"NO");
         }];
    } else {
        // iOS 10 notifications aren't available; fall back to iOS 8-9 notifications.
        UIUserNotificationType allNotificationTypes =
        (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
        UIUserNotificationSettings *settings =
        [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
        [application registerUserNotificationSettings:settings];
    }

    [application registerForRemoteNotifications];

    ...
}

是否缺少某些东西或做错了？

这是用于发送通知的代码。 （哪个可以在我的android应用程序上正常工作）

<?php

$notification = array('title' => 'Test' ,'body' => 'Test', 'sound' => 'default', "click_action" => "4");



$ids = array(The token);


sendPushNotification($notification, $ids);

function sendPushNotification($notification, $ids)
{

    $apiKey = 'xxx';


    $post = array(
                    'registration_ids'  => $ids,
                    'data' => $notification,
                    'priority' => 'high',       
                    'content_avalaible' => 'true',
                 );

    $headers = array( 
                        'Authorization: key=' . $apiKey,
                        'Content-Type: application/json'
                    );

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');

    curl_setopt($ch, CURLOPT_POST, true);

    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));

    $result = curl_exec($ch);


    if (curl_errno($ch))
    {
        echo 'FCM error: ' . curl_error($ch);
    }

    curl_close($ch);

    echo $result;
}

?>

谢谢
