I am trying to get data (like name,gender,birthday, profile picture etc) of the user that is logged in. I have tried following two codes, shown below:
//first: Create request for user's Facebook data
FBRequest *request = [FBRequest requestForMe];
// Send request to Facebook
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(@"%@", error);
if (!error) {
// result is a dictionary with the user's Facebook data
NSDictionary *userData = (NSDictionary *)result;
NSLog(@"%@....",userData);
_facebookID = userData[@"id"];
_name = userData[@"name"];
_location = userData[@"location"][@"name"];
_gender = userData[@"gender"];
_birthday = userData[@"birthday"];
NSLog(@"%@",_name);
_picutreURL = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large&return_ssl_resources=1", _facebookID]];
self.nameField.text=_name;
self.profilePicture.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:_picutreURL]];
self.profileInfo.text=[NSString stringWithFormat:@"%@, Live in %@ , Born on %@",_gender,_location,_birthday];
}
}];
// 2nd:Fetch user data
[FBRequestConnection
startForMeWithCompletionHandler:^(FBRequestConnection *connection,
id<FBGraphUser> user,
NSError *error) {
if (!error) {
NSString *userInfo = @"";
// Example: typed access (name)
// - no special permissions required
userInfo = [userInfo
stringByAppendingString:
[NSString stringWithFormat:@"Name: %@\n\n",
user.name]];
// Example: typed access, (birthday)
// - requires user_birthday permission
userInfo = [userInfo
stringByAppendingString:
[NSString stringWithFormat:@"Birthday: %@\n\n",
user.birthday]];
// Example: partially typed access, to location field,
// name key (location)
// - requires user_location permission
userInfo = [userInfo
stringByAppendingString:
[NSString stringWithFormat:@"Location: %@\n\n",
user.location[@"name"]]];
// Example: access via key (locale)
// - no special permissions required
userInfo = [userInfo
stringByAppendingString:
[NSString stringWithFormat:@"Locale: %@\n\n",
user[@"locale"]]];
// Example: access via key for array (languages)
// - requires user_likes permission
if (user[@"languages"]) {
NSArray *languages = user[@"languages"];
NSMutableArray *languageNames = [[NSMutableArray alloc] init];
for (int i = 0; i < [languages count]; i++) {
languageNames[i] = languages[i][@"name"];
}
userInfo = [userInfo
stringByAppendingString:
[NSString stringWithFormat:@"Languages: %@\n\n",
languageNames]];
}
// Display the user info
NSLog(@"%@",userInfo);
}
}];
But I get null string in output and detected this error:
Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x9499320 {com.facebook.sdk:ParsedJSONResponseKey={
body = {
error = {
code = 2500;
message = "An active access token must be used to query information about the current user.";
type = OAuthException;
};
};
code = 400;
}, com.facebook.sdk:HTTPStatusCode=400}
What should I do?
I believe I had the same problem, and the way I just got it working was to add
FBSession.activeSession = fbSession;
once the initial handler came back successfully. (fbSession
is whatever variable you have with the facebook session in it.) I just randomly stumbled upon this (I think from another StackOverflow post). But I don't see it in the docs, and by grepping, it doesn't seem to be in any of the Sample apps. So maybe there's a larger issue with my code that I'm not seeing? I'd be interested to hear how others avoid setting the activeSession, and still are able to run startForMeWithCompletionHandler
.
