Iphone 获取范围内具有的位置详细信息
我正在开发一个应用程序。我想从一个位置到另一个位置获取所有位置。我知道两个位置的纬度和经度值。因此,如何从第一个位置到第二个位置获取所有位置的详细信息。如果您使用mongo,您可以使用$nearSphere for mysql。请遵循以下教程 所有教程都是mysql和php的Iphone 获取范围内具有的位置详细信息,iphone,Iphone,我正在开发一个应用程序。我想从一个位置到另一个位置获取所有位置。我知道两个位置的纬度和经度值。因此,如何从第一个位置到第二个位置获取所有位置的详细信息。如果您使用mongo,您可以使用$nearSphere for mysql。请遵循以下教程 所有教程都是mysql和php的-(void)getCordinate:(NSString*)strOrigin:(NSString*)strDestination - (void)getCordinate :(NSString *)strOrigin

使用此代码获取从起点到目的地的所有纬度和经度
im不是移动应用程序开发人员,但方法是一样的。你需要从数据库或其他地方获取位置列表,找到接近目标值的lat和long值,并按lat和long的顺序对它们进行排序。你想在两个位置之间选择哪种位置?或者你想显示这两个位置之间的直线?我想知道获取两个位置之间的Restreents列表。结果以从起点到终点的纬度和经度数组返回
