Question

ios开发的新手，需要一些帮助。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，以便我可以分享短信。任何人都可以建议或指向我可以看到的示例。< / p>

请和谢谢。

猜猜我不够清楚。我想使用corelocation来将当前的lat和long传递给这个字符串（http：/maps.google.com/maps？q = loc：currentLat，-currentLong）并加载它到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

对于任何有兴趣的人，我都是自己解决的。
