在iOS7.1中用户杀死App时进行地理围栏

Question

在iOS7.1中，当用户杀死某个应用时，地理围栏是否仍有效？

如果地理围栏检测到设备正在进入或退出该区域，它是否可以触发本地通知（即使用户已杀死该应用）？

Answer 1

你GeoFencing仍然可以工作，就像推送通知/或存折一样，它仍会为你的应用程序生成通知。即使app未在后台运行，波纹管功能也会触发。

    - (void)locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
    NSString *event = [NSString stringWithFormat:@"didExitRegion %@ at %@",         region.identifier, [NSDate date]];
[self updateWithEvent:event];
     //implement local notification:    
UIApplication *app                = [UIApplication sharedApplication];
UILocalNotification *notification = [[UILocalNotification alloc] init];
[[UIApplication sharedApplication] cancelAllLocalNotifications];

if (notification == nil)
    return;
notification.alertBody = [NSString stringWithFormat:@"Did You Lock Your House?"];
notification.alertAction = @"Lock House";
notification.soundName = UILocalNotificationDefaultSoundName; 
notification.applicationIconBadgeNumber = 1;
[app presentLocalNotificationNow:notification];

[notification release];

}
