需求：显示目标点以及自己所在位置，且有方向跟随。
先来张效果图：

1、初始化地图

 -(MAMapView*)mapView{
      if(!_mapView) {
          self.mapView = [ZWMemoryCache.cache MAMapView];

          _mapView.frame=CGRectMake(0,kSafeTop,KW,KH-kSafeTop);

          _mapView.delegate=self;

          //1.1、显示用户位置（重点）

          _mapView.showsUserLocation = YES;

          //地图跟着位置移动

          _mapView.userTrackingMode = MAUserTrackingModeFollow;

          //设置定位精度

          _mapView.desiredAccuracy = kCLLocationAccuracyBest;

          //设置定位距离

          _mapView.distanceFilter = 5.0f;



          _mapView.mapType = MKMapTypeStandard;

          //1.2、新增点A

           CLLocationCoordinate2D location = CLLocationCoordinate2DMake([_pointMod.position.coordinates[1] doubleValue], [_pointMod.position.coordinates[0] doubleValue]);//纬度，经度

          MAPointAnnotation *pointAnnotation = [[MAPointAnnotation alloc] init];

          pointAnnotation.coordinate= location;

          pointAnnotation.title=_pointMod.name;

          pointAnnotation.subtitle= [NSStringstringWithFormat:@"%@",_pointMod.position.coordinates];

          [_mapViewaddAnnotation:pointAnnotation];       

           //将目标经纬度设置为地图中心店

          self.mapView.centerCoordinate= location;
      }
      return _mapView;
  }

2、在代理方法中修改定位点的图标，以及去除默认的淡蓝色圈

- (MAAnnotationView*)mapView:(MAMapView*)mapView viewForAnnotation:(id)annotation
{
    //系统默认的当前位置点

    if ([annotation isKindOfClass:[MAUserLocation class]]) {

        staticNSString*userLocationStyleReuseIndetifier =@"userLocationStyleReuseIndetifier";

        MAAnnotationView*annotationView = [mapViewdequeueReusableAnnotationViewWithIdentifier:userLocationStyleReuseIndetifier];

        if(annotationView ==nil) {

            annotationView = [[MAPinAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:userLocationStyleReuseIndetifier];

        }

        //2.1、设置为带箭头的图标

        annotationView.image= [UIImageimageNamed:@"userPosition"];

        self.userLocationAnnotationView= annotationView;



        //2.2、去掉高德地图淡蓝色精度圈

        MAUserLocationRepresentation *r = [[MAUserLocationRepresentation alloc] init];

        r.showsAccuracyRing = false;///精度圈是否显示，默认YES

        [mapViewupdateUserLocationRepresentation:r];



        returnannotationView;

    }

    //新增的点A

    else if ([annotation isKindOfClass:[MAPointAnnotation class]]) {

        staticNSString*pointReuseIndentifier =@"annotationReuseIndetifier";

        MAPinAnnotationView*annotationView = (MAPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndentifier];

        if(annotationView ==nil)

        {

            annotationView = [[MAPinAnnotationViewalloc]initWithAnnotation:annotationreuseIdentifier:pointReuseIndentifier];

        }

        annotationView.canShowCallout=YES;      //设置气泡可以弹出，默认为NO

        annotationView.animatesDrop=YES;        //设置标注动画显示，默认为NO

//        annotationView.draggable = YES;        //设置标注可以拖动，默认为NO

//        annotationView.pinColor = MAPinAnnotationColorPurple;

        //2.3、设置自定义点样式

        annotationView.image= [UIImageimageNamed:@"searchPosition"];



        returnannotationView;

    }
    return nil;
}

3、设置箭头指示方位

 - (void)mapView:(MAMapView*)mapView didUpdateUserLocation:(MAUserLocation*)userLocation updatingLocation:(BOOL)updatingLocation
{
    //设置箭头指示方位

    if(!updatingLocation &&self.userLocationAnnotationView!=nil) {

        [UIView animateWithDuration:0.1 animations:^{

            doubledegree = userLocation.heading.trueHeading-self.mapView.rotationDegree;

            self.userLocationAnnotationView.transform = CGAffineTransformMakeRotation(degree * M_PI / 180.f );

        }];
    }
}
