问题 With the release of iOS6 Apple wants us to use didUpdateLocations instead of didUpdateToLocation. Can anyone explain how to properly use didUpdateLocations? 回答1: I asume you used the following delegate to get the last position? - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation The delegate above is deprecated in iOS 6. Now the following should be used: - (void)locationManager:(CLLocationManager *)manager

问题 I have to get current location of my user and I have done it by using CLLocationManager . I can get user's current city or area. I have an array of cities and have to check that which city is closest to the current location of user. Is it possible and if yes then how I can achieve it. EDIT: I have to show some deals or offers on the basis of user's location. If user is not from the city which is in my list, then I have to find out the nearest city and have to show offers from that city. 来源：

问题 Is it possible to invoke didUpdateLocations inside the Timer ? I mean.. _timer = Timer.scheduledTimer(timeInterval: 10, target: self, selector: #selector(_:didUpdateLocations:)), userInfo: nil, repeats: true) Is that going to work ? If yes then it is going to update location every 10 seconds ? 回答1: You can't invoke didUpdateLocations. If you want frequent updates, your best choice is the Standard location service: The standard location service is most appropriate for apps that deliver

问题 My app uses geofencing as well as iBeacon monitoring. I have set up some CLCircularRegion as well as CLBeaconRegion to be monitor. So whenever, i hit a new beacon or new location, then - (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region { NSLog(@"CLCircularRegion or CLBeaconRegion?, I am confused!!!"); } will be invoked. Can anybody tell me how to find out which region(i.e.,CLCircularRegion/CLBeaconRegion) is calling the delegate. 回答1: Finally found my own
