最终效果图：

一， plist及frame的配置

      1 ,info.plist文件中添加 Privacy - Location When In Use Usage Description（需要时开启定位，另一个是Privacy - Location Always Usage Description 一直开启定位）。

      2, 添加framework框架，MapKit.framework与CoreLocation.framework,并分别在需要定位的视图中导入头文件：CoreLocation/CoreLocation.h 与 MapKit/MapKit.h

二，开启定位

     1, 在项目中加入代理协议：CLLocationManagerDelegate,MKMapViewDelegate

@interface ViewController : UIViewController
    
     @property (nonatomic,strong) CLLocationManager *locationManager;@property (nonatomic,strong) CLGeocoder *geocoder;@property (nonatomic,strong) MKMapView *mapViewL;@end
    

    2, 实现代理协议并开启定位

@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];        self.locationManager = [[CLLocationManager alloc]init];    self.locationManager.delegate = self;    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;    self.geocoder = [[CLGeocoder alloc]init];    self.placeDic = [[NSDictionary alloc]init];    MKUserLocation *userLOCation = [[MKUserLocation alloc]init];    _userLOcation = userLOCation;        [self startLocationForYou];        _placeLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 100, 300, 50)];    [self.view addSubview:_placeLabel];        _mapViewL = [[MKMapView alloc]initWithFrame:CGRectMake(0, 200, self.view.bounds.size.width, self.view.bounds.size.height - 200)];    _mapViewL.delegate = self;    [self.view addSubview:_mapViewL];    _mapViewL.userTrackingMode = MKUserTrackingModeFollow;    _mapViewL.mapType = MKMapTypeStandard;}//开始定位- (void)startLocationForYou{        if (![CLLocationManager locationServicesEnabled] || [CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedWhenInUse){                NSLog(@"定位功能已经打开");        [_locationManager requestWhenInUseAuthorization];    }        //调用定位信息    [self.locationManager startUpdatingLocation];}

    3, 获得用户当前经纬度

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray
    
      *)locations{        CLLocation *location = [locations lastObject];    CLLocationCoordinate2D coord = location.coordinate;//    NSLog(@"经度：%f 纬度：%f 海拔: %f 航向：%f 速度：%f",coord.longitude,coord.latitude,location.altitude,location.course,location.speed);    [self getGeocoder:coord.longitude Atitude:coord.latitude];    //    [manager stopUpdatingLocation];}
    

三， 根据经纬度通过地理反编码得到当前街道信息

- (void)getGeocoder:(CLLocationDegrees )longitude Atitude:(CLLocationDegrees )atitude{        CLLocation *location = [[CLLocation alloc]initWithLatitude:atitude longitude:longitude];    [_geocoder reverseGeocodeLocation:location completionHandler:^(NSArray
    
      * _Nullable placemarks, NSError * _Nullable error) {                CLPlacemark *placeMark = [placemarks firstObject];        //        if (self.placeDic.count == 0){                    self.placeDic = placeMark.addressDictionary;                    [self labelView:_placeDic[@"FormattedAddressLines"][0]];//            NSLog(@"详细地址：%@ ==== ",placeMark.addressDictionary);//        }    }];}- (void)locationManager:(CLLocationManager *)manager       didFailWithError:(NSError *)error{    if (error.code == kCLErrorDenied) {                NSLog(@"Error:%@",error);        // 提示用户出错原因，可按住Option键点击 KCLErrorDenied的查看更多出错信息，可打印error.code值查找原因所在    }}
    

四， 显示地图并对当前用户位置进行定位跟随

- (void)touchesBegan:(NSSet
    
      *)touches withEvent:(UIEvent *)event{        [self startLocationForYou];    _mapViewL.userTrackingMode = MKUserTrackingModeFollow;    MKCoordinateSpan span = MKCoordinateSpanMake(0.002, 0.002);    MKCoordinateRegion regin = MKCoordinateRegionMake(_userLOcation.location.coordinate, span);    [_mapViewL setRegion:regin animated:YES];}- (void)labelView:(NSString *)placeLabel{            self.placeLabel.text = placeLabel;    self.placeLabel.numberOfLines = 0;    self.placeLabel.font = [UIFont systemFontOfSize:15];    }- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation{            _userLOcation = userLocation;    //Setting area    MKCoordinateSpan span = MKCoordinateSpanMake(0.002, 0.002);    MKCoordinateRegion regin = MKCoordinateRegionMake(userLocation.location.coordinate, span);    [_mapViewL setRegion:regin animated:YES];    }@end
