地图轨迹纠偏的使用和路径平滑移动

效果图:

废话不多说,直接上代码

//画历史轨迹并进行轨迹纠偏
-(void)historyCorrect:(NSArray<MATraceLocation *> *)Arr{
    
    MATraceManager *manager = [[MATraceManager alloc] init];
    
    //[self clear];
    __weak typeof(self) weakSelf = self;
   __unused NSOperation *op = [manager queryProcessedTraceWith:Arr type:-1 processingCallback:^(int index, NSArray<MATracePoint *> *points) {
        [weakSelf addSubTrace:points toMapView:weakSelf.mapV];
    } finishCallback:^(NSArray<MATracePoint *> *points, double distance) {
        NSLog(@"numPoint: %lu",(unsigned long)points.count);
        sumDistance = [NSString stringWithFormat:@"总里程:%fkm",distance];
        weakSelf.queryOperation = nil;
        [weakSelf addFullTrace:points toMapView:weakSelf.mapV];
        
    } failedCallback:^(int errorCode, NSString *errorDesc) {
        NSLog(@"Error: %@", errorDesc);
        weakSelf.queryOperation = nil;
    }];
    self.queryOperation = op;
    
}

- (void)addFullTrace:(NSArray<MATracePoint*> *)tracePoints toMapView:(MAMapView *)mapView{
    //获取起始点和终点
    [self optainStartPointEndPoint:tracePoints];
    //此类用于定义一个由多个点相连的多段线
    MAMultiPolyline *polyline = [self makePolyLineWith:tracePoints];
    if(!polyline) {
        return;
    }
    [mapView setVisibleMapRect:polyline.boundingMapRect edgePadding:UIEdgeInsetsMake(30, 70, 30, 50) animated:YES];

    [self.processedOverlays addObject:polyline];
    [mapView addOverlays:self.processedOverlays];
    
}
- (void)addSubTrace:(NSArray<MATracePoint*> *)tracePoints toMapView:(MAMapView *)mapView {
    MAMultiPolyline *polyline = [self makePolyLineWith:tracePoints];
    if(!polyline) {
        return;
    }
    [mapView removeOverlay:polyline];
    [self.processedOverlays removeAllObjects];
    
    MAMapRect visibleRect = [mapView visibleMapRect];
    if(!MAMapRectContainsRect(visibleRect, polyline.boundingMapRect)) {
        MAMapRect newRect = MAMapRectUnion(visibleRect, polyline.boundingMapRect);
        [mapView setVisibleMapRect:newRect];
    }
    [self.processedOverlays addObject:polyline];
    [mapView addOverlay:polyline];
    
}

//划线
- (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;
    }
    //分段绘制，根据经纬度坐标数据生成多段线
    MAMultiPolyline *polyline = [MAMultiPolyline polylineWithCoordinates:pCoords count:tracePoints.count drawStyleIndexes:@[@10, @60]];
    if(pCoords) {
        free(pCoords);
    }
    return polyline;
}
//绘制覆盖物
#pragma mark - MAMapViewDelegate
- (MAOverlayRenderer *)mapView:(MAMapView *)mapView rendererForOverlay:(id <MAOverlay>)overlay
{
    if ([overlay isKindOfClass:[MAMultiPolyline class]])
    {
        MAPolylineRenderer *polylineView = [[MAPolylineRenderer alloc] initWithPolyline:(MAPolyline *)overlay];
        
        polylineView.lineWidth   = 8.f;
       //路线填充图片
        [polylineView loadStrokeTextureImage:[UIImage imageNamed:@"arrowTexture.png"]];

        return polylineView;
    }
    
    return nil;
}

到这里轨迹纠偏划线就好了.接下来开始添加平滑移动动画

self.annotation.coordinate = coords1[0];
        
        MAAnimatedAnnotation *anno = self.annotation;
        CLLocationCoordinate2D coords[1];
        __weak __typeof(anno) WeakAnno = anno;
       // 添加移动动画 ***************************************
//这里要注意.这个方法是在返回数据里面控制每一个点进行相应的赋值
        [anno addMoveAnimationWithKeyCoordinates:coords count:sizeof(coords) / sizeof(coords[0]) withDuration:_duration withName:nil completeCallback:^(BOOL isFinished) {
                
                if ([[dict[@"v"] stringValue] isEqualToString:@"0"] || i == _data.count) {
                    WeakAnno.title = @"停留";
                    WeakAnno.subtitle = [NSString stringWithFormat:@"%@ s", [self timeExchange:dict[@"t"]]];
                    
                }else{
                    WeakAnno.title = [NSString stringWithFormat:@"%@ (km/h)", dict[@"v"]];
                    WeakAnno.subtitle = [NSString stringWithFormat:@"%@ s", [self timeExchange:dict[@"t"]]];
                    
                }
