开始也是 导入MapKit.framework
IOS8要请求定位
获取本地位置有两种方法 1 MKMapItem *mylocation = [MKMapItem mapItemForCurrentLocation];
2 代理方法调用返回 userLocation（内有经纬度） 它有经纬度再转：
CLLocationCoordinate2D coords1 = CLLocationCoordinate2DMake(23.127923,113.388557);
MKMapItem *currentLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:coords1 addressDictionary:nil]];

import "ViewController.h"

        #import <MapKit/MapKit.h>

        @interface ViewController ()<MKMapViewDelegate>{
            NSArray *_items;

        }

        @property (weak, nonatomic) IBOutlet MKMapView *mapView;

        @end

        @implementation ViewController

        - (void)viewDidLoad {
            [super viewDidLoad];
            
            // 地图类型
            //    MKMapTypeStandard = 0, 默认 标准
            //    MKMapTypeSatellite, 卫星
            //    MKMapTypeHybrid 混合 ＝ 标准 + 卫星
            self.mapView.mapType = MKMapTypeStandard;
            
            // 用户位置跟踪模式
            //    MKUserTrackingModeNone = 0, //用户位置，不请允许跟踪
            //    MKUserTrackingModeFollow, // 用户位置允许跟踪
            //    MKUserTrackingModeFollowWithHeading,用户位置允许跟踪(方向)
            self.mapView.userTrackingMode = MKUserTrackingModeFollow;
            
            // 设置mapView代理
            self.mapView.delegate = self;

             MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:coords2 addressDictionary:nil]];
             _items = [NSArray arrayWithObjects:mylocation, toLocation, nil];
            
            NSDictionary *options = @{ MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving, MKLaunchOptionsMapTypeKey: [NSNumber numberWithInteger:MKMapTypeStandard], MKLaunchOptionsShowsTrafficKey:@YES };

            userLocation.subtitle = @"天河";

            //当前的位置详细描述，要显示哪个城市，哪个区-(反地理编码)
            //当前位置信息
            NSLog(@"%f----%f",userLocation.coordinate.latitude,userLocation.coordinate.longitude);
            
            // 2.设置显示的region
            //MKCoordinateSpan span = MKCoordinateSpanMake(0.193626, 0.145513);

        #pragma mark 在此方法， 动画效果不起作用，其它方法方法可以
            //[self.mapView setRegion:region animated:YES];
