从NSdictionary获取值JSON

Question

我有一个看起来那样的字典：

{
    "from": 0,
    "to": 1412045889232,
    "series": [
        {
            "component": "Table",
            "points": [
                {
                    "ts": "1409745374148", //time stamps
                    "value": "34"
                },
                {
                    "ts": "1409745564148",
                    "value": "36"
                }
            ]
        }
 {
            "component": "Table2",
            "points": [
                {
                    "ts": "1409745374148", //time stamps
                    "value": "43"
                },
                {
                    "ts": "1409745564148",
                    "value": "39"
                }
            ]
        }
    ]
}

我可以轻松地从中获取。 该系列还：

NSLog(@"/n Fetched component = %@", [[dict objectForKey:@"series"] valueForKey:@"component"] );
NSLog(@"/n Fetched points = %@", [[dict objectForKey:@"series"] valueForKey:@"points"] );

我想要的是获得定义ts的值 任何想法？

Answer 1

  NSDictionary *jsonDictionary  ; // Contains Json Serialized Data
    NSArray *seriesArray = [jsonDictionary valueForKey:@"series"];


    for (NSDictionary *innerDictionary in seriesArray)
    {
        NSLog(@"%@" ,[innerDictionary valueForKey:@"component"]);


        for (NSDictionary *pointsDict in [innerDictionary valueForKey:@"points"])
        {
            NSLog(@"%@" , [pointsDict valueForKey:@"ts"]);
        }

    }
