Ios 收到UILocalnotification时无振动

我不明白。这是我的代码，我在其中配置我的

LocalNotification

并启动它。它工作正常，但没有振动。我想当我收到通知时应该会有震动

我尝试了AudioServicesPlayAlertSound（ksystemsSoundId_振动）/AudioServicesPlaySystemSound（ksystemsSoundId_振动），但没有成功

- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region
{

UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.soundName = UILocalNotificationDefaultSoundName;
if(state == CLRegionStateInside)
{
    notification.alertBody = @"Bla Bla";
    wasWelcomeBefore = TRUE;
}
else if(state == CLRegionStateOutside)
{
    notification.alertBody = @"Bla";
}
else
{
    NSLog(@"locationManager didDetermineState OTHER for %@", region.identifier);
    return;
}

if ([[UIApplication sharedApplication] applicationState] != UIApplicationStateActive){
    if (!isNotifiForFirstBeacon && wasWelcomeBefore) {
        AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
        NSDictionary *dataDict = [NSDictionary dictionaryWithObject:[NSNumber     numberWithBool:isNotifiForFirstBeacon]                                                                    forKey:@"isFirstBeacon"];
        isNotifiForFirstBeacon = TRUE;
        notification.userInfo = dataDict;
        [[UIApplication sharedApplication] presentLocalNotificationNow:notification];
    }
}

根据文档，它确实声明：请注意，在发送通知时，您不能以编程方式使设备振动，因为用户可以控制警报是否伴随振动。看，我想你指的是音频服务音频（kSystemSoundID_振动）；正确的？我插入它进行测试或希望它能工作。因为在发出通知时，没有振动。
