当屏幕锁定时，Apple Push Notification (remote)无法工作。Apple的通知选项卡上也没有显示任何内容

Question

当我推送通知时，iPhone屏幕打开(可能是因为应用程序被唤醒了)。但是，锁定屏幕或通知选项卡上不会显示任何通知。

当屏幕锁定时，iOS通知不起作用。通知选项卡中也不显示任何内容。当应用程序在后台(屏幕解锁)或前台时，Banner工作正常。

我使用以下代码来使用node-apn推送通知(我也在存储库上打开了一个票证：https://github.com/argon/node-apn/issues/418)：

function pushNotificationToMany() {
    console.log("Sending the same notification each of the devices with one call to pushNotification.");
    var note = new apn.notification();
    note.setAlertTitle("Hello from my app");
    note.setAlertText("Hello, world!");
    note.setCategory("message");
    note.setContentAvailable(1);
    note.badge = 1;

    service.pushNotification(note, tokens);
}

pushNotificationToMany();

我的AppDelegate.m中的iOS代码包含以下函数：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    NSLog(@"Registering for push notifications...");
    UIMutableUserNotificationCategory* notificationCategory = [[UIMutableUserNotificationCategory alloc] init];
    notificationCategory.identifier = @"message";
    NSSet *categories = [NSSet setWithObjects:notificationCategory, nil];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:categories]];
    NSDictionary *payload = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (payload)
        NSLog(@"payload is : %@", payload);
    return YES;
}
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings // NS_AVAILABLE_IOS(8_0);
{
    [application registerForRemoteNotifications];
}
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{

    NSLog(@"deviceToken: %@", deviceToken);
    NSString * token = [NSString stringWithFormat:@"%@", deviceToken];
    //Format token as you need:
    token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
    token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
    token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];

}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    NSLog(@"remote notification user info %@", userInfo);
}
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler {
    NSLog(@"another remote notification user info %@", userInfo);
    if(application.applicationState == UIApplicationStateInactive) {

        NSLog(@"Inactive");

        //Show the view with the content of the push

        handler(UIBackgroundFetchResultNewData);

    } else if (application.applicationState == UIApplicationStateBackground) {

        NSLog(@"Background");

        //Refresh the local model

        handler(UIBackgroundFetchResultNewData);

    } else {

        NSLog(@"Active");

        //Show an in-app banner

        handler(UIBackgroundFetchResultNewData);

    }
}

看起来我需要添加UIMutableUserNotificationAction才能得到我想要的结果。下面的代码可以工作：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    NSLog(@"Registering for push notifications...");

    UIMutableUserNotificationAction *notificationAction1 = [[UIMutableUserNotificationAction alloc] init];
    notificationAction1.identifier = @"Accept";
    notificationAction1.title = @"Accept";
    notificationAction1.activationMode = UIUserNotificationActivationModeBackground;
    notificationAction1.destructive = NO;
    notificationAction1.authenticationRequired = NO;

    UIMutableUserNotificationAction *notificationAction2 = [[UIMutableUserNotificationAction alloc] init];
    notificationAction2.identifier = @"Reject";
    notificationAction2.title = @"Reject";
    notificationAction2.activationMode = UIUserNotificationActivationModeBackground;
    notificationAction2.destructive = YES;
    notificationAction2.authenticationRequired = YES;

    UIMutableUserNotificationAction *notificationAction3 = [[UIMutableUserNotificationAction alloc] init];
    notificationAction3.identifier = @"Reply";
    notificationAction3.title = @"Reply";
    notificationAction3.activationMode = UIUserNotificationActivationModeForeground;
    notificationAction3.destructive = NO;
    notificationAction3.authenticationRequired = YES;

    UIMutableUserNotificationCategory *notificationCategory = [[UIMutableUserNotificationCategory alloc] init];
    notificationCategory.identifier = @"Email";
    [notificationCategory setActions:@[notificationAction1,notificationAction2,notificationAction3] forContext:UIUserNotificationActionContextDefault];
    [notificationCategory setActions:@[notificationAction1,notificationAction2] forContext:UIUserNotificationActionContextMinimal];

    NSSet *categories = [NSSet setWithObjects:notificationCategory, nil];

    UIUserNotificationType notificationType = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
    UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:notificationType categories:categories];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];

    [[UIApplication sharedApplication] registerForRemoteNotifications];
//    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:categories]];
    NSDictionary *payload = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
    if (payload)
        NSLog(@"payload is : %@", payload);
    return YES;
}
