问题描述
我想在我的 UISearchBar 附近放置一个 Geolocation 按钮，点击该按钮时，它应该返回 zip(例如 20043).我将使用 ZIP 中的值来获取我附近的建筑物列表.
I want to place a Geolocation button near my UISearchBar, which on clicking, it should return the zip (eg. 20043). I will be using the value from the ZIP to get the list of buildings near me.
如果有人可以帮助我使用位置按钮，我将不胜感激，以及实现仅返回 ZIP (integer) 的方法是什么?custom UIButton 是否适用于位置按钮?
I would appreciate it if someone could help me with the location Button, and what are the methods to implement to return just the ZIP (integer) ? And would a custom UIButton work for the location button ?
谢谢！
推荐答案
在 iOS 4 中没有转发地理编码(将地址转换为 lat/long)，在 iOS 5 中有一些增强(这是在 NDA 下，所以你需要访问 Apple 开发者网站).
In iOS 4 there is no forward geocoded (turning an address into lat/long), there are some enhancements to this in iOS 5 (this is under NDA, so you'll need to visit the Apple developers site).
