您可以通过此代码检查 locationServicesEnabled 以及您的应用程序是否允许定位服务:

You can check the for locationServicesEnabled and if the location service is allowed for your application by this code:

if([CLLocationManager locationServicesEnabled] && [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied) {
    //do your works
} else {
   //show an alert
}
