## ``  `- (void)viewDidLoad { [self startLocation]; } //开始定位 -(void)startLocation{ self.locationManager = [[CLLocationManager alloc] init]; self.locationManager.delegate = self; [self.locationManager requestWhenInUseAuthorization]; if ([[[UIDevice currentDevice]systemVersion]doubleValue]>=8.0) { [self.locationManager requestWhenInUseAuthorization]; [self.locationManager requestAlwaysAuthorization]; } [self.locationManager startUpdatingLocation]; if ([CLLocationManager locationServicesEnabled]) { self.locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters; self.locationManager.distanceFilter = kCLDistanceFilterNone; }else { NSLog(@"open fail"); } } #pragma mark - CoreLocation 代理 #pragma mark 跟踪定位代理方法，每次位置发生变化即会执行（只要定位到相应位置） -(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations { CLLocation *location=[locations lastObject]; CLLocationCoordinate2D coordinate=location.coordinate; NSLog(@"经度：%f,纬度：%f",coordinate.longitude,coordinate.latitude); self.longitude=coordinate.longitude; self.latitude=coordinate.latitude; //如果不需要实时定位，使用完即使关闭定位服务 [self.locationManager stopUpdatingLocation]; [self weiZhi]; } -(void)weiZhi { self.geocoder=[[CLGeocoder alloc]init]; CLLocation *rr=[[CLLocation alloc]initWithLatitude:self.latitude longitude:self.longitude]; [self.geocoder reverseGeocodeLocation:rr completionHandler:^(NSArray *placemarks, NSError *error) { CLPlacemark *mark=[placemarks objectAtIndex:0]; UILabel *currentLocation=[[UILabel alloc]initWithFrame:CGRectMake(220, 15, 100, 20)]; currentLocation.text=[NSString stringWithFormat:@"%@",mark.subLocality]; [self.locationView addSubview:currentLocation]; }]; } -(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status { switch (status) { case kCLAuthorizationStatusNotDetermined: if ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) { [self.locationManager requestWhenInUseAuthorization]; } break; default: break; } } //当定位出现错误时就会调用这个方法。 - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error { NSLog(@"error-%@",error); }`     定位当前的位置。对于 CLPlacemark 还有许多属性，不仅仅可以给出当前位置，还可以给出其他信息，后续研究。。。。    ##
