1、注册获取应用KEY（http://lbs.amap.com/api/ios-sdk/guide/create-project/get-key）
2、添加MAMapView至需要的页面中

pragma mark - init

• (MAMapView )mapView
  {
  if (!_mapView) {
  _mapView = [[MAMapView alloc] initWithFrame:self.view.bounds];
  _mapView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
  _mapView.delegate = self;
  _mapView.showsScale = NO; //不显示比例尺
  // _mapView.showsCompass = NO; //关闭指南针
  _mapView.compassOrigin = CGPointMake(20kRating, 20*kRating);//指南针的左上角坐标点位置
  _mapView.centerCoordinate = CLLocationCoordinate2DMake(22.57, 113.90);//设置地图中心点
  _mapView.zoomLevel = 3;
  _mapView.minZoomLevel = 3;
  _mapView.rotateCameraEnabled = NO;
  //取出logo图标
  [_mapView.subviews enumerateObjectsUsingBlock:^(__kindof UIView * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
  if ([obj isKindOfClass:[UIImageView class]]) {
  UIImageView * logoM = obj;
  logoM.layer.contents = (__bridge id)[UIImage imageNamed:@""].CGImage;
  }
  }];
  }
  return _mapView;
  }
  //在viewDidLoad中添加
  [self.view addSubview:self.mapView];
  3、设置定点标注信息
  MAAnimatedAnnotation *anno = [[MAAnimatedAnnotation alloc] init];
  anno.coordinate = CLLocationCoordinate2DMake(positionModel.latitude, positionModel.longitude);//标注点的经纬度
  self.annotation = anno;
  //添加标注点至地图
  [self.mapView addAnnotation:self.annotation];
  //显示标注点(会自动缩放地图已到达显示所有需要显示的标注点，若不添加该句，地图显示为设置的缩放的等级)
  [self.mapView showAnnotations:@[self.annotation] animated:YES];
  4、设置经纬度数组（根据数组数动态生成CLLocationCoordinate2D结构体数组的内存空间个数）
  CLLocationCoordinate2D *coords = (CLLocationCoordinate2D *)malloc([array count] * sizeof(CLLocationCoordinate2D));
  5、地图状态设置（可让地图根据某个角度动态的移动地图）
  [self.mapView setMapStatus:[MAMapStatus statusWithCenterCoordinate:coors[1]
  zoomLevel:18
  rotationDegree:(360-self.vehicleModel.vehicle.direction)
  cameraDegree:0
  screenAnchor:CGPointMake(0.5, 0.5)]
  animated:YES
  duration:10];

6、在需要的地方调取configTrace并传递相应的数值
/*

• 轨迹纠偏
  */

• (NSArray *)positionTransformTraceLocation
  {
  NSMutableArray *array = [NSMutableArray array];
  if (self.historyModel.positions.count > 0) {
  for (ZJPositionModel *positionModel in self.historyModel.positions) {
  MATraceLocation *location = [[MATraceLocation alloc] init];
  location.loc = CLLocationCoordinate2DMake(positionModel.latitude, positionModel.longitude);
  location.speed = positionModel.speed;
  location.time = positionModel.gpsTime;
  location.angle = positionModel.direction;

        [array addObject:location];
    }
  

  }

  return array;
  }

• (void)configTrace
  {
  if (self.historyModel.positions.count == 1) {//只有一个点不纠正轨迹
  if (self.processedOverlays && self.processedOverlays.count > 0) {
  [self.mapView removeOverlays:self.processedOverlays];
  [self.processedOverlays removeAllObjects];
  }

  } else {
  __weak typeof(self) weakSelf = self;

    MATraceManager *manager = [[MATraceManager alloc] init];
    NSOperation *operation = [manager queryProcessedTraceWith:[self positionTransformTraceLocation]
                                                         type:-1
                                           processingCallback:^(int index, NSArray<MATracePoint *> *points) {
                                               [weakSelf addSubTrace:points toMapView:weakSelf.mapView];
                                               
                                           } finishCallback:^(NSArray<MATracePoint *> *points, double distance) {
                                               weakSelf.queryOperation = nil;
                                               [weakSelf addFullTrace:points toMapView:weakSelf.mapView];
                                               
                                           } failedCallback:^(int errorCode, NSString *errorDesc) {
                                               NSLog(@"Error: %@", errorDesc);
                                               weakSelf.queryOperation = nil;
                                               
                                           }];
    self.queryOperation = operation;
  

  }
  }

• (MAMultiPolyline )makePolyLineWith:(NSArray<MATracePoint> *)tracePoints {
  if(tracePoints.count == 0) {
  return nil;
  }

  CLLocationCoordinate2D *pCoords = malloc(sizeof(CLLocationCoordinate2D) * tracePoints.count);
  if(!pCoords) {
  return nil;
  }

  for(int i = 0; i < tracePoints.count; ++i) {
  MATracePoint *p = [tracePoints objectAtIndex:i];
  CLLocationCoordinate2D *pCur = pCoords + i;
  pCur->latitude = p.latitude;
  pCur->longitude = p.longitude;
  }

  MAMultiPolyline *polyline = [MAMultiPolyline polylineWithCoordinates:pCoords count:tracePoints.count drawStyleIndexes:@[@10, @60]];

  if(pCoords) {
  free(pCoords);
  }
  return polyline;
  }

• (void)addFullTrace:(NSArray<MATracePoint*> *)tracePoints toMapView:(MAMapView *)mapView{
  MAMultiPolyline *polyline = [self makePolyLineWith:tracePoints];
  if(!polyline) {
  return;
  }
  [mapView removeOverlays:self.processedOverlays];
  [self.processedOverlays removeAllObjects];

  [mapView setVisibleMapRect:MAMapRectInset(polyline.boundingMapRect, -1000, -1000)];

  [self.processedOverlays addObject:polyline];
  [mapView addOverlays:self.processedOverlays];
  [mapView showOverlays:self.processedOverlays animated:YES];
  }

• (void)addSubTrace:(NSArray<MATracePoint*> *)tracePoints toMapView:(MAMapView *)mapView {
  MAMultiPolyline *polyline = [self makePolyLineWith:tracePoints];

  return;
  }

  [mapView setVisibleMapRect:newRect];
  }

  [self.processedOverlays addObject:polyline];
  [mapView addOverlay:polyline];
  [mapView showOverlays:@[polyline] animated:YES];
  }

pragma mark - mapview delegate

• (MAOverlayRenderer *)mapView:(MAMapView *)mapView rendererForOverlay:(id <MAOverlay>)overlay
  {
  if ([overlay isKindOfClass:[MAMultiPolyline class]])
  {
  MAPolylineRenderer *polylineRenderer = [[MAPolylineRenderer alloc] initWithPolyline:(MAMultiPolyline *)overlay];
  polylineRenderer.lineWidth = 16.f;
  polylineRenderer.strokeImage = [UIImage imageNamed:@"car_trace"];

    return polylineRenderer;
  

  }

  return nil;
