Facebook Graph API: result in array or in json object

Question

I have little bit confuse between graph api result.Can any one explain which default object method is facebook using when we fetch data via graph api. Have any application account setting for access data in json object or in array object, because some time i found user data in encrypted and some time non encrypted. I found user email id in two way from facebook graph api. One is:

{
   "id": "100001114785800",
   "name": "Stella Jackson",
   "first_name": "Stella",
   "last_name": "Jackson",
   "link": "http://www.facebook.com/profile.php?id=100001114785800",
   "birthday": "04/16/1987",
   "gender": "female",
   "email": "[email protected]",
   "timezone": 5.5,
   "locale": "en_US",
   "updated_time": "2010-10-08T13:26:10+0000"
}

And second one is:

{
   "id": "100001114785800",
   "name": "Stella Jackson",
   "first_name": "Stella",
   "last_name": "Jackson",
   "link": "http://www.facebook.com/profile.php?id=100001114785800",
   "birthday": "04/16/1987",
   "gender": "female",
   "email": "stella_ja\u0040live.com",
   "timezone": 5.5,
   "locale": "en_US",
   "updated_time": "2010-10-08T13:26:10+0000"
}

Have any idea?

Thanks

Any JSON parser should read both those emails as the same. \u0040 is just the escaped version of the at-sign. — John Flatness

The '\u0040' is same as obfuscated or Unicode form of '@' symbol. Most Parsers can convert that to the original symbol.

Check this for list of Unicode character set.

Use this to get the dictionary n value of email for ios

FbGraphResponse *fb_graph_response = [fbGraph doGraphGet:@"me" withGetVars:nil];
NSLog(@"getMeButtonPressed:  %@", fb_graph_response.htmlResponse);
NSDictionary *dictionary=[fb_graph_response.htmlResponse JSONValue];
NSLog(@"%@",[dictionary valueForKey:@"email"]);

Hope it helps you.

The easiest way would be to take the email string and do something like this (objective c):

NSString *email = @"stella_ja\u0040live.com"; // or whatever you use to get it
email = [NSString stringByReplacingOccurencesOfString:@"\u0040" withString:@"@"];

So in other words, use string methods to replace "\u0040" with "@".

you can simply replace \u0040 with @ but during this replace compiler will consider "\" as escape sequence and will skip this without making changes.

What you do like this below:

NSString *strEmail = @"stella_ja\u0040live.com";
[strEmail stringByReplacingOccurrencesOfString:@"\\u0040" withString:@"@"];
NSLog(@"strEmail: %@", strEmail);
