[SOLVED] Social framework returns "(#803) Cannot query users by their username (username)" when trying to get user feed

Social framework returns "(#803) Cannot query users by their username (username)" when trying to get user feed

I'm using iOs social framework in order to retrieve facebook feeds from a certain user. For that purpose, after authenticating I'm doing the following:

NSURL *requestURL = [NSURL URLWithString:@"https://graph.facebook.com/username"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET
                                                  URL:requestURL parameters:nil];
request.account = self.facebookAccount;

[request performRequestWithHandler:^(NSData *data, NSHTTPURLResponse *response, NSError *error) { ... }];

The response returns:

error =     {
        code = 803;
        message = "(#803) Cannot query users by their username (username)";
        type = OAuthException;
    };

The same works if I use /me instead of the username, but I want to retrieve someone else public feed.

I also tried using the user's id which also works for my user, but I it doesnt work for other users, the request returns the following:

code = 2500;
        message = "The global ID 100008339709776 is not allowed. Please use the application specific ID instead.";
        type = OAuthException;

I also tried passing the access token as parameter but the behavior is the same.

Any ideas?

Solution

Already pointed out in the comments, but you are not supposed to use the username anymore and you can´t access data of users who did not authorize your App.
