使用 Map Kit 如何找到我的位置？

我需要在 Map Kit 中显示我当前的位置，我该怎么做？

self.map.showsUserLocation = TRUE;

没有显示我的位置，而是显示地图上其他位置的点？我需要找到访问应用程序的位置。请帮助我。提前致谢

I need to display my current position in Map Kit, how can I do this ?

self.map.showsUserLocation = TRUE;

is not showing my location instead a point somewhere else in the map? I need to find the location from where I am accessing the application.
Please help me in this..
Thanks in advance

您需要使用位置管理器来获取您当前的位置。然后获取经纬度值并创建注释并显示在地图上。如果使用map.showsUserLocation = TRUE;它将显示您在实际设备中的当前位置。

注意 - 在模拟器地图套件中显示苹果总部位于库比蒂诺某处 - 我不太记得了。
