jsonString转NSDictionary

NSData *webData = [ @"{\"\":
               {\"name\": \"Jerry\",\"age\": \"12\"},
              \"2\":
               {\"name\": \"Bob\",\"age\": \"16\"} }" dataUsingEncoding:NSUTF8StringEncoding ]; NSError *error;
NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:webData options: error:&error]; /*
NSJSONReadingMutableContainers = (1UL << 0),  //  创建可变的数组或字典来接收  0 NSJSONReadingMutableLeaves = (1UL << 1), // 指定在JSON对象可变字符串被创建为NSMutableString的实例 1
NSJSONReadingAllowFragments = (1UL << 2) //  指定解析器应该允许不属于的NSArray或NSDictionary中的实例顶层对象   2

*/
NSLog(@"JSON DIct: %@", jsonDict);
输出如下: JSON DIct: {
= {
age = ;
name = Jerry;
};
= {
age = ;
name = Bob;
};
}
如果你的jsonString是下面格式的话:

[ {"id":,"title":"销售员","number":,"education":,"money":,"years":,"companyname":"腾讯网络技术有限公司","company":},

 {"id":,"title":"程序员","number":,"education":,"money":,"years":,"companyname":"腾讯网络技术有限公司","company":} ]
那调用[NSJSONSerialization JSONObjectWithData:webData options:0 error:&error]返回的就是NSArray, NSArray里面是2个NSDictionary。
