Don't receive email and public profile using Facebook 4.4.0 SDK
I am currently working on Facebook SDK 4.4.0. Before 4.4.0, in 4.3.0 we received an email, public_profile with the following code
NSArray *arrFBPermission = [[NSArray alloc]initWithObjects:@"email",@"public_profile", nil];
[loginUsingFB logInWithReadPermissions:arrFBPermission handler:^(FBSDKLoginManagerLoginResult *result, NSError *error){
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error){
if (!error){
NSString *fnm = [result valueForKey:@"first_name"];
NSString *lnm = [result valueForKey:@"last_name"];
}
else{
Nslog("%@", error localizedDescription);
}
}];
}
Now in the new SDK (i.e. 4.4.0) I am not getting these values. What for? I want email, first_name, last_name, id from Facebook.

There is a small change as of Facebook 4.4 SDK. You need to request the c parameter FBSDKGraphRequest
that you want to get from your Facebook account.
Your code has nil
in parameters:
Update your code with options like:
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email, birthday, bio ,location , friends ,hometown , friendlists"}]
If you want to login to Facebook with a custom button, you can use the complete code like this:
- (IBAction)btnFacebookPressed:(id)sender {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior = FBSDKLoginBehaviorBrowser;
[login logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error)
{
if (error)
{
// Process error
}
else if (result.isCancelled)
{
// Handle cancellations
}
else
{
if ([result.grantedPermissions containsObject:@"email"])
{
NSLog(@"result is:%@",result);
[self fetchUserInfo];
[login logOut]; // Only If you don't want to save the session for current app
}
}
}];
}
-(void)fetchUserInfo
{
if ([FBSDKAccessToken currentAccessToken])
{
NSLog(@"Token is available : %@",[[FBSDKAccessToken currentAccessToken]tokenString]);
[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields": @"id, name, link, first_name, last_name, picture.type(large), email"}]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error)
{
NSLog(@"resultis:%@",result);
}
else
{
NSLog(@"Error %@",error);
}
}];
}
}
I hope this works for you.
