JSON和嵌套的NSDictionary

Question

在解析JSON响应之后,我得到一个包含其他字典的NSDictionary,这些字典是一些事先未知的键的值(308,1):

{
"308":{
    "id":"308",
    .....

},
"1":{
    "id":"1",
    .....
     }
}

我怎么在这里使用valueForKey,因为我不知道密钥？如何访问嵌套字典？谢谢!

Answer 1

NSDictionary *myDict;
...

NSArray *keys = [myDict allKeys]; //NSArray of dictionary's keys

for (id key in keys) //'foreach' loop for all keys
{
   id aValue = [myDict objectForKey: key]; //getting object from the dictionary
   if([aValue isKindOfClass:[NSDictionary class]])
   {
       //Object is a nested dictionary
       ...
   }
}
