MapView的应用-创新互联

MapView在8.0之后,用法有了一些新的用法(代理方法),在此之前需要导入

#import

//创建位置服务对象

  locationManager = [[CLLocationManager alloc] init];

  locationManager.desiredAccuracy = kCLLocationAccuracyBest;

  //设置定位代理

  locationManager.delegate = self;

  //如果实在iOS8.0之后，我们需要添加以下操作

  //1.调用方法--requestWhenInUseAuthorization 或者 requestAlwaysAuthorization

  //2.

  if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {

      [locationManager requestWhenInUseAuthorization];

  }

  //开始定位

  [locationManager startUpdatingLocation];

}

- (void)didReceiveMemoryWarning {

  [super didReceiveMemoryWarning];

  // Dispose of any resources that can be recreated.

}

#pragma mark -CLLocationManagerDelegate

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation

{

  NSLog(@"定位成功");

  //停止定位

  [locationManager stopUpdatingLocation];

  CLLocationCoordinate2D coordinate = newLocation.coordinate;

  NSLog(@"位置：纬度：%.2f----经度：%.2f", coordinate.latitude, coordinate.longitude);

}

- (void)locationManager:(CLLocationManager *)manager

    didUpdateLocations:(NSArray *)locations

{

  NSLog(@"新方法定位成功");

  //停止定位

  [locationManager stopUpdatingLocation];

  CLLocation *location = [locations lastObject];

  CLLocationCoordinate2D coordinate = location.coordinate;

  NSLog(@"位置：纬度：%.2f----经度：%.2f", coordinate.latitude, coordinate.longitude);

  //在iOS5.0之前使用位置反编码

  MKReverseGeocoder *mkReverse = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate];

  mkReverse.delegate = self;

  //开始反编码

  [mkReverse start];

  CLGeocoder *geocoder = [[CLGeocoder alloc] init];

  [geocoder reverseGeocodeLocation:location

                  completionHandler:^(NSArray *placemarks, NSError *error) {

                      NSLog(@"---------CLGeocoder---------------");

                      for (CLPlacemark *place in placemarks) {

                          NSLog(@"name,%@",place.name);                       // 位置名

                          NSLog(@"thoroughfare,%@",place.thoroughfare);       // 街道

                          NSLog(@"subThoroughfare,%@",place.subThoroughfare); // 子街道

                          NSLog(@"locality,%@",place.locality);               // 市

                          NSLog(@"subLocality,%@",place.subLocality);         // 区

                          NSLog(@"country,%@",place.country);                 // 国家

                      }

                  }

    ]; // CLGeocoder反编码

}

#pragma mark -MKReverseGeocoderDelegate

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)place

{

  NSLog(@"-----------MKReverseGeocoderDelegate----------");

  NSLog(@"name,%@",place.name);                       // 位置名

  NSLog(@"thoroughfare,%@",place.thoroughfare);       // 街道

  NSLog(@"subThoroughfare,%@",place.subThoroughfare); // 子街道

  NSLog(@"locality,%@",place.locality);               // 市

  NSLog(@"subLocality,%@",place.subLocality);         // 区

  NSLog(@"country,%@",place.country);                 // 国家

}

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error

{

  NSLog(@"error is %@", error);
