【问题描述】：

ios 开发新手，需要一点帮助。 我正在尝试使用 CoreLocation 将用户当前位置加载到格式化为 Google 地图链接 (http://maps.google.com/maps?q=loc:userLatitude,-userLongitude) 的 UITextField，以便我可以在短信中分享。任何人都可以建议或指向我可以查看的示例。

请，谢谢。

我猜我不够清楚。我想使用 corelocation 将当前的纬度和经度传递给这个字符串 (http:/maps.google.com/maps?q=loc:currentLat,-currentLong) 并加载它到一个 UITextField。 即：如果你在多伦多， uitextField 会有这个链接

http://maps.google.com/maps?q=loc:43.653433,-79.380341

对于任何感兴趣的人，我自己解决了。

What parameters should I use in a Google Maps URL to go to a lat-lon?的可能重复

这不是重复的
