Question

如何从HereMap中删除所有地图对象？

HereMap SDK仅提供

- (BOOL)removeMapObject:(nonnull NMAMapObject *)object
- (BOOL)removeMapObjects:(nonnull NSArray<NMAMapObject *> *)objects

Answer 1

你最有可能将NMAMapObject添加到地图中，我建议创建一个添加到地图中的所有对象的可变数组，所以当你这样做时

//in viewDidLoad for instance create an empty NSMutableArray called mapObjects
[self.mapView addMapObject:self.mapRoute];
[mapObjects addObject:mapObject];

然后当你想删除它们时，你将能够做到：

[self.mapView removeMapObject:mapObjects]; 

如果这对您有用，请告诉我......
