我正在使用 Geofencing 作为我的一个申请 . 但我有一个问题 . 当应用程序处于 Background 模式时，我的应用程序未被调用 **- (void)locationManager:(CLLocationManager )manager didDetermineState:(CLRegionState)state forRegion:(CLRegion )region .
我在设置中检查 Background app refresh 标志是 ON .
以下是我的代码：
- (void)locationManager:(CLLocationManager *)manager didDetermineState:(CLRegionState)state forRegion:(CLRegion *)region
if (state == CLRegionStateInside)
{
NSLog(@"is in target region");
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.alertBody = @"You are IN of REGION";
notification.fireDate = [NSDate date];
NSTimeZone* timezone = [NSTimeZone defaultTimeZone];
notification.timeZone = timezone;
notification.alertAction = @"Show";
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
else
{
NSLog(@"is out of target region");
UILocalNotification *notification = [[UILocalNotification alloc] init];
notification.alertBody = @"You are OUT of REGION";
notification.fireDate = [NSDate date];
NSTimeZone* timezone = [NSTimeZone defaultTimeZone];
notification.timeZone = timezone;
notification.alertAction = @"Show";
notification.soundName = UILocalNotificationDefaultSoundName;
[[UIApplication sharedApplication] scheduleLocalNotification:notification];
}
}
CLLocationManager 设置正确 . 我研究它，但没有得到适当的解决我的问题 . 任何人都可以帮助我吗？
谢谢
