解析和风天气API的json(objective-C实现)

暑假在家闲着没事干,心血来潮想做个天气预报APP玩玩,听说和风天气API很好,于是注册并试了下,结果它的JSON是这样的(拿我的家乡武义为例子)

{"HeWeather data service 3.0":[{"aqi":{"city":{"aqi":"","pm10":"","pm25":"","qlty":"良"}},"basic":{"city":"武义","cnty":"中国","id":"CN101210906","lat":"28.530000","lon":"119.480000","update":{"loc":"2016-08-16 17:52","utc":"2016-08-16 09:52"}},"daily_forecast":[{"astro":{"sr":"05:32","ss":"18:40"},"cond":{"code_d":"","code_n":"","txt_d":"晴","txt_n":"多云"},"date":"2016-08-16","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"无持续风向","sc":"微风","spd":""}},{"astro":{"sr":"05:32","ss":"18:39"},"cond":{"code_d":"","code_n":"","txt_d":"晴","txt_n":"晴"},"date":"2016-08-17","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"东风","sc":"微风","spd":""}},{"astro":{"sr":"05:33","ss":"18:38"},"cond":{"code_d":"","code_n":"","txt_d":"晴","txt_n":"晴"},"date":"2016-08-18","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"东风","sc":"微风","spd":""}},{"astro":{"sr":"05:33","ss":"18:37"},"cond":{"code_d":"","code_n":"","txt_d":"多云","txt_n":"多云"},"date":"2016-08-19","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"东风","sc":"微风","spd":""}},{"astro":{"sr":"05:34","ss":"18:36"},"cond":{"code_d":"","code_n":"","txt_d":"多云","txt_n":"多云"},"date":"2016-08-20","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"东风","sc":"微风","spd":""}},{"astro":{"sr":"05:34","ss":"18:35"},"cond":{"code_d":"","code_n":"","txt_d":"多云","txt_n":"多云"},"date":"2016-08-21","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"东风","sc":"微风","spd":""}},{"astro":{"sr":"05:35","ss":"18:34"},"cond":{"code_d":"","code_n":"","txt_d":"多云","txt_n":"多云"},"date":"2016-08-22","hum":"","pcpn":"0.0","pop":"","pres":"","tmp":{"max":"","min":""},"vis":"","wind":{"deg":"","dir":"东风","sc":"微风","spd":""}}],"hourly_forecast":[{"date":"2016-08-16 19:00","hum":"","pop":"","pres":"","tmp":"","wind":{"deg":"","dir":"东南风","sc":"微风","spd":""}},{"date":"2016-08-16 22:00","hum":"","pop":"","pres":"","tmp":"","wind":{"deg":"","dir":"东南风","sc":"微风","spd":""}}],"now":{"cond":{"code":"","txt":"晴"},"fl":"","hum":"","pcpn":"","pres":"","tmp":"","vis":"","wind":{"deg":"","dir":"东风","sc":"4-5","spd":""}},"status":"ok","suggestion":{"comf":{"brf":"极不舒适","txt":"白天天气晴好、炎热，您会感到酷热难耐，极为不适，请注意防暑降温。"},"cw":{"brf":"较适宜","txt":"较适宜洗车，未来一天无雨，风力较小，擦洗一新的汽车至少能保持一天。"},"drsg":{"brf":"炎热","txt":"天气炎热，建议着短衫、短裙、短裤、薄型T恤衫等清凉夏季服装。"},"flu":{"brf":"少发","txt":"各项气象条件适宜，发生感冒机率较低。但请避免长期处于空调房间中，以防感冒。"},"sport":{"brf":"较适宜","txt":"天气较好，户外运动请注意防晒。推荐您进行室内运动。"},"trav":{"brf":"较不宜","txt":"天气较好，温度比较高，中午时段尽量不要外出，如外出可选择水上娱乐等清凉项目。并请注意防暑和防晒。"},"uv":{"brf":"强","txt":"紫外线辐射强，建议涂擦SPF20左右、PA++的防晒护肤品。避免在10点至14点暴露于日光下。"}}}]}

你赢了,我选择死亡

由于奇葩的格式连json解析工具也不能用,好吧我就不厌其烦地层层解析….

注意:{}代表NSDictionary,[]和()代表NSArray。也算是学到了一点
