需求：顯示目標點以及自己所在位置，且有方向跟隨。
先來張效果圖：

1、初始化地圖

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

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

          _mapView.delegate=self;

          //1.1、顯示用戶位置（重點）

          _mapView.showsUserLocation = YES;

          //地圖跟著位置移動

          _mapView.userTrackingMode = MAUserTrackingModeFollow;

          //設置定位精度

          _mapView.desiredAccuracy = kCLLocationAccuracyBest;

          //設置定位距離

          _mapView.distanceFilter = 5.0f;



          _mapView.mapType = MKMapTypeStandard;

          //1.2、新增點A

           CLLocationCoordinate2D location = CLLocationCoordinate2DMake([_pointMod.position.coordinates[1] doubleValue], [_pointMod.position.coordinates[0] doubleValue]);//緯度，經(jīng)度

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

          pointAnnotation.coordinate= location;

          pointAnnotation.title=_pointMod.name;

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

          [_mapViewaddAnnotation:pointAnnotation];       

           //將目標經(jīng)緯度設置為地圖中心店

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

2、在代理方法中修改定位點的圖標，以及去除默認的淡藍色圈

- (MAAnnotationView*)mapView:(MAMapView*)mapView viewForAnnotation:(id)annotation
{
    //系統(tǒng)默認的當前位置點

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

        staticNSString*userLocationStyleReuseIndetifier =@"userLocationStyleReuseIndetifier";

        MAAnnotationView*annotationView = [mapViewdequeueReusableAnnotationViewWithIdentifier:userLocationStyleReuseIndetifier];

        if(annotationView ==nil) {

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

        }

        //2.1、設置為帶箭頭的圖標

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

        self.userLocationAnnotationView= annotationView;



        //2.2、去掉高德地圖淡藍色精度圈

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

        r.showsAccuracyRing = false;///精度圈是否顯示，默認YES

        [mapViewupdateUserLocationRepresentation:r];



        returnannotationView;

    }

    //新增的點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;      //設置氣泡可以彈出，默認為NO

        annotationView.animatesDrop=YES;        //設置標注動畫顯示，默認為NO

//        annotationView.draggable = YES;        //設置標注可以拖動，默認為NO

//        annotationView.pinColor = MAPinAnnotationColorPurple;

        //2.3、設置自定義點樣式

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



        returnannotationView;

    }
    return nil;
}

3、設置箭頭指示方位

 - (void)mapView:(MAMapView*)mapView didUpdateUserLocation:(MAUserLocation*)userLocation updatingLocation:(BOOL)updatingLocation
{
    //設置箭頭指示方位

    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 );

        }];
    }
}
