如何在后台启动iOS应用

Question

I'm developing an app that listens the beacons, I want while app is in background and is near a beacon want the app opens. How can it be done? I can put the moment of opening in one of these two methods:

-(void)locationManager:(CLLocationManager *)manager 
   didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region {
 //..........

}

-(void)locationManager:(CLLocationManager *)manager 
       didEnterRegion:(CLRegion *)region {
     //.........

}

OS can wake the app up in the background, the app can post a local notification, but there is no way for it to become the frontmost app and wake up the device. Notification can play a sound though, so you have some way to get the user's attention.
