Question

关于如何使用openstreetmap数据和route-me在ios中使用离线地图，我经历了这个link。我生成了map2sqlite文件并通过链接将其集成到route-me中。但是地图没有加载所需的区域。是否有关于将map sqlite文件集成到route-me中的示例或教程。关于此的教程或工作示例将更有帮助。

当我在设备上运行我的代码时，我得到了以下日志。

Answer 1

您的日志似乎表明您的数据库格式/内容不正确：

template<class T,class ...Args> std::vector<T> generate_with_index(size_t qty,Args ...args)
{
    std::vector<T> result;
    result.reserve(qty);
    for(size_t i = 0 ; i < qty ; ++qty)
        result.emplace_back(i, args...);
    return result;
}

由于您的数据库中没有任何图块，因此无法显示任何图块。

我建议您查看Mapbox SDK和their sample application。
