從json響應中獲取ID的值

Question

我是iPhone應用開發中的新手。我想從Facebook獲取用戶ID（我的ID）。我如何獲得ID？控制檯中的輸出如下。

感謝

- (void)request:(FBRequest *)request didLoad:(id)result 
{ 
    NSLog(@"result is %@",result); 

} 

輸出控制檯是在這裏：

{ 
email = "kestwalg@gmail.com"; 
"first_name" = Gaurav; 
gender = male; 
hometown =  { 
    id = 1231243212321; 
    name = Haridwar; 
}; 
id = 1213213231231; 
"last_name" = K; 
link = "http://www.facebook.com/kestwal.75"; 
locale = "en_US"; 
location =  { 
    id = 123123123123; 
    name = "New Delhi, India"; 
}; 
name = "Gaurav Kestwal"; 
timezone = "5.5"; 
"updated_time" = "2012-07-10T06:46:25+0000"; 
username = "gaur.75"; 
verified = 1; 
work =  (
      { 
     employer =    { 
      id = 12312312312; 
      name = "NKAPs Intellects Noida"; 
     }; 
     position =    { 
      id = 213123123213; 
      name = "iPhone Application Developer"; 
     }; 
     "start_date" = "0000-00"; 
    } 
); 

}

Answer 1

實現SBJson。

加載JSON響應到的NSDictionary：

​​

從字典像然後閱讀：

NSString *idString = [myDictionary objectForKey:@"id"]; 

Answer 2

你只需要解析它，幸運的是有沒有iPhone那麼容易很多方法可以做到。您可以使用例如這個框架：JSON framework

Answer 3

嘗試是：上線的NSString * idString =

- (void)request:(FBRequest *)request didLoad:(id)result { 
    NSString *jsonString = [NSString stringWithString:[result JSONRepresentation]]; 
    NSDictionary *userDict = [jsonString JSONValue]; 
    // do something with the values in the dictionary... 
}
