iOS7.1中App被用户终止时的地理围栏

Question

在iOS7.1中，当用户杀死一个应用程序时，地理围栏还能工作吗？

如果地理围栏检测到设备正在进入或退出区域，它是否可以触发本地通知(即使用户已经关闭了应用程序)？

Answer 1

你的GeoFencing仍然可以工作，它的工作原理就像推送通知/或者存折一样，它仍然会为你的应用生成通知。即使应用程序不在后台运行，bellow函数也会触发。

    - (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];

}
