『貳』 iOS開發，想知道國家氣象局api返回過來的天氣數據將天氣總共描述為幾種類型，
之前做過相關的App，網上搜出來的，直接粘貼了。有用請採納哦~
國家氣象局提供的天氣預報介面
介面地址：
http://www.weather.com.cn/data/sk/101010100.html
http://www.weather.com.cn/data/cityinfo/101010100.html
http://m.weather.com.cn/data/101010100.html

1. XML介面 http://flash.weather.com.cn/wmaps/xml/china.xml 這個是全國天氣的根節點，列出所有的省，其中的pyName欄位是各個省XML的文件名，比如北京的是beijing，那就意味著北京的XML地址為 http://flash.weather.com.cn/wmaps/xml/beijing.xml 一個省的天氣，其中列出該省各個市的數據，北京就列出各個區。 tmp1是最低溫低，tmp2是最高溫度，url非常重要，我們一會兒再說。state1和state2是神馬轉神馬，每個數代表一個天氣現象。天氣現象非常多，我本想全部分析出來，後來直接放棄了這個想法。因為我看到了一個城市的天氣現象的編碼是26...我現在知道的有0.晴 1.多雲 2.陰 6.雨夾雪 7.小雨 8.中雨 13.陣雪 14.小雪 其中後來發現知道這個沒用，這個數字的主要作用是檢索圖片的！！！
2. 圖片介面 http://m.weather.com.cn/img/c0.gif http://m.weather.com.cn/img/b0.gif http://www.weather.com.cn/m/i/weatherpic/29x20/d0.gif http://www.weather.com.cn/m2/i/icon_weather/29x20/n00.gif 這個圖就是天氣現象0（晴）的圖片，其他天氣現象的圖片依此類推。c打頭的圖片是20*20像素的，b打頭的是50*46像素的，d打頭的是反白的圖標，29*20像素，n打頭的是夜間反白圖標，29*20像素，注意這里的文件名是兩位數字！ 也許還有更多的圖標，等待大家發掘啦~
3. JSON介面 真沒想到~居然有JSON介面~JSON在iPhone上分析起來要比XML簡單很多 http://m.weather.com.cn/data/101010200.html 這個是北京的JSON數據，那個HTML的名字是根據上文XML中的url得到的。這個JSON中包含了實時數據、7天天氣預報、氣象指數等豐富的數據
獲取省級代碼：http://www.weather.com.cn/data/list3/city.xml?level=1獲取城市代碼(比如安徽是22)：http://www.weather.com.cn/data/list3/city22.xml?level=2獲取區域代碼（比如安慶是2206）：http://www.weather.com.cn/data/list3/city2206.xml?level=3獲取到安徽省安慶市望江縣的代碼是220607然後去加上中國代碼請求URL：http://m.weather.com.cn/data/101220607.html就可以獲取當地天氣。
另外再給幾個有用的探索得到的URL：天氣 FLASH實況：http://flash.weather.com.cn/sk2/101220607.xml實況FLASH：http://flash.weather.com.cn/sk2/shikuang.swf?id=101220607
三級選擇菜單（註明，這里有四個INPUT，其中有一個被隱藏了，可用FIREFOX改下源代碼查看）：http://www.weather.com.cn/static/custom/search3.htm
實時天氣（很有用哦）：http://www.weather.com.cn/data/sk/101220607.html
