关于json解析问题

NSURL *url=[NSURL URLWithString:@"http://192.168.1.101/website1/studentinfo.ashx?sno=sno20130811002"];
    NSError *error;
    NSURLRequest *request=[NSURLRequest requestWithURL:url];
    NSData *data=[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSDictionary *dic=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&error];
    NSDictionary *dic_student=[dic objectForKey:@"StudentInfo"];
    NSLog(@"Result:%@",dic_student);

打印字典dic_student     输出：
Result:(
        {
        Sage = 23;
        Sdept = "\U73af\U5883\U5de5\U7a0b";
        Sname = zhanghuan;
        Sno = SNO20130811002;
        Spec = "\U73af\U5883\U5b89\U5168";
        Ssex = "\U7537";
    }
)
此时dic_student字典里面的键值访问不到为什么呢??字典的allKeys为空，里面的学号姓名等属性都访问不到

[解决办法]


NSArray *dic_student_array = [dic objectForKey:@"StudentInfo"];
NSDictionary *dic_student=[dic_student_array objectAtIndex:0];

改下试试，JSON数据里看，StudentInfo是个数组...
