在哪里可以找到适用于 iPhone 应用程序的 JSON 天气 API？

Question

我发现的大多数都使用 XML，我宁愿只使用 JSON Objective-C 源代码。

有什么建议吗？

我见过这个：

Answer 1

Weather Underground 有一个返回 JSON 和 XML 的 API。公平的定价，加上每天 500 个免费的开发者电话。除了 NOAA 官方气象站外，Weather Underground 还拥有许多当地气象站，其中很多位于 SF 地区。

注意：此 API 现已被 Yahoo 弃用，并且 将无法工作！

我在闲逛了一段时间后发现了一个未记录的雅虎天气 API。这是一个示例链接：

http://weather.yahooapis.com/forecastjson?w=12844782&u=c

w

后面的值是WOEID，

u

是单位。我确信还有更多选项可用于配置 URL。

它看起来像这样：
