Objectivec didReceiveRemoteNotification：当应用程序处于后台并且未连接到Xcode时未调用fetchCompletionHandler

我有一个非常奇怪的问题，我实现了:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

用于静默远程推送通知.

我的代码如下:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
    NSInteger pushCode = [userInfo[@"pushCode"] integerValue];
    NSLog(@"Silent Push Code Notification: %i", pushCode);
    NSDictionary *aps = userInfo[@"aps"];
    NSString *alertMessage = aps[@"alert"];

    if (pushCode == kPushCodeShowText) {
        UILocalNotification *localNotif = [[UILocalNotification alloc] init];
        localNotif.fireDate = [NSDate date];
        localNotif.timeZone = [NSTimeZone defaultTimeZone];
        localNotif.alertBody = alertMessage;
        localNotif.alertAction = @"OK";
        localNotif.soundName = @"sonar.aiff";
        // localNotif.applicationIconBadgeNumber = 0;
        localNotif.userInfo = nil;
        [[UIApplication sharedApplication] presentLocalNotificationNow:localNotif];

        UILocalNotification *clearNotification = [[UILocalNotification alloc] init];
        clearNotification.fireDate = [NSDate date];
        clearNotification.timeZone = [NSTimeZone defaultTimeZone];
        clearNotification.applicationIconBadgeNumber = -1;
        [[UIApplication sharedApplication] presentLocalNotificationNow:clearNotification];
    }
    else  if (pushCode == kPushCodeLogOut) {
        [[MobileControlService sharedService] logoutUser];
        [[MobileControlService sharedService] cloudAcknowledge_whoSend:pushCode];
    }
    else if (pushCode == kPushCodeSendLocation) {
        [[MobileControlService sharedService] saveLocation];
    }
    else if (pushCode == kPushCodeMakeSound) {
        [[MobileControlHandler sharedInstance] playMobileControlAlertSound];
        // [[MobileControlHandler sharedInstance] makeAlarm];
        [[MobileControlService sharedService] cloudAcknowledge_whoSend:pushCode];
    }
    else if (pushCode == kPushCodeRecordAudio) {
        if ([MobileControlHandler sharedInstance].isRecordingNow) {
            [[MobileControlHandler sharedInstance] stopRecord];
        } else {
            [[MobileControlHandler sharedInstance] startRecord];
        }
        [[MobileControlService sharedService] cloudAcknowledge_whoSend:pushCode];
    }
    completionHandler(UIBackgroundFetchResultNewData);
}

- (void)saveLocation {
    bgTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{
        [[UIApplication sharedApplication] endBackgroundTask:bgTask];
    }];

    char *hostname;
    struct hostent *hostinfo;
    hostname = "http://m.google.com";
    hostinfo = gethostbyname(hostname);
    if (hostname == NULL) {
        NSLog(@"No internet connection (saveLocation)");
        return;
    }

    if (self.locationManager.location.coordinate.latitude == 0.0 || self.locationManager.location.coordinate.longitude == 0.0) {
        NSLog(@"saveLocation - coordinates are 0.0.");
        return;
    }

    NSLog(@"saveLocation - trying to get location.");
    NSString *postBody = [NSString stringWithFormat:@"Lat=%@&Lon=%@&Date=%@&userID=%@&batteryLevel=%@&version=%@&accuracy=%@&address=%@", self.myInfo.lat, self.myInfo.lon, self.myInfo.date, self.myInfo.userID, self.myInfo.batteryLevel, self.myInfo.version, self.myInfo.accuracy, self.myInfo.address];

NSURL *completeURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@/saveLocation", WEB_SERVICES_URL]];
NSData *body = [postBody dataUsingEncoding:NSUTF8StringEncoding];

[request setHTTPMethod:@"POST"];
[request setValue:kAPP_PASSWORD_VALUE forHTTPHeaderField:kAPP_PASSWORD_KEY];
[request setHTTPBody:body];
[request setValue:[NSString stringWithFormat:@"%d", body.length] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];


if (__iOS_7_And_Heigher) {
    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
    NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        if (error) {
            NSLog(@"saveLocation Error: %@", error.localizedDescription);
        } else {
            NSString *responseXML = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
            NSLog(@"\n\nResponseXML(saveLocation):\n%@", responseXML);
            [self cloudAcknowledge_whoSend:kPushCodeSendLocation];
        }
    }];
    [dataTask resume];
}
else {
    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
        if (connectionError) {
            NSLog(@"saveLocation Error: %@", connectionError.localizedDescription);
        } else {
            NSString *responseXML = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
            NSLog(@"\n\nResponseXML(saveLocation):\n%@", responseXML);
            [self cloudAcknowledge_whoSend:kPushCodeSendLocation];
        }
    }];
}
}

- (void)startBackgroundTask {
    bgTask = [[UIApplication sharedApplication] beginBackgroundTaskWithExpirationHandler:^{
        [[UIApplication sharedApplication] endBackgroundTask:bgTask];
    }];
}

- (void)endBackgroundTask {
    if (bgTask != UIBackgroundTaskInvalid) {
        [[UIApplication sharedApplication] endBackgroundTask:bgTask];
        bgTask = UIBackgroundTaskInvalid;
    }
}

[self endBackgroundTask]在cloudAcknowledge函数的末尾.

EDIT:

有效载荷是这样的:
