在 iphone 应用程序中生成 KML 文件 [英] Generate KML file within iphone app

问题描述

在我的应用程序中，我必须在 MKAnnotation 和 MKOverlay 类的帮助下在 MKMapView 中绘制用户位置和目标位置之间的路线.我已经阅读了苹果的 KMLViewer 示例代码，他们提到在编程步骤之外创建 KML 文件，但我需要在 iPhone 应用程序编程中生成 KML 文件.

In my app i have to draw route between user location and destination location in MKMapView with help of MKAnnotation and MKOverlay classes. I had gone through the KMLViewer sample code from apple in there they mentioned to create KML file outside the programming steps, but i need KML file generation inside iPhone app programming.

有可能吗?我需要帮助来做这件事..

is it possible? and i need help on doing that..
