NSJSONSerialization
1.IOS中Json解析的四种方法
参考 enuola
2.代码示例
1 -(void) testNSJSONSerialization
2 {
3 // define error
4 NSError *error;
5 // define url request
6 NSURLRequest *urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString: @"http://m.weather.com.cn/data/101010100.html"]];
7 // get reponse data from url request
8 NSData *dataResponse = [NSURLConnection sendSynchronousRequest: urlRequest returningResponse: nil error: nil];
9 // use nsjson transfer data to dictionary
10 NSDictionary *dictionaryWeather = [NSJSONSerialization JSONObjectWithData: dataResponse options: NSJSONReadingMutableLeaves error: &error];
11 // get weather info from weather dictionary
12 NSDictionary *dictionaryWeatherInfo = [dictionaryWeather objectForKey: @"weatherinfo"];
13 // output weather of today
14 NSLog(@"今天是 %@ %@ %@ 的天气状况是：%@ %@ ", [dictionaryWeatherInfo objectForKey: @"date_y"], [dictionaryWeatherInfo objectForKey: @"week"],[dictionaryWeatherInfo objectForKey: @"city"], [dictionaryWeatherInfo objectForKey: @"weather1"], [dictionaryWeatherInfo objectForKey: @"temp1"]);
15 // output
16 NSLog(@"Weather字典里面的内容为--》%@", dictionaryWeather);
17 }
