Question

I'm trying to get facebook user birthday. So far I am successfully getting user first_name, last_name,email,name,gender except birthday

self.loginButton.publishPermissions = @[@"basic_info", @"email", @"user_friends"];
self.loginButton.delegate =self;
FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
loginManager.loginBehavior = FBSDKLoginBehaviorSystemAccount;
[loginManager logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { 

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{@"fields" : @"first_name, last_name,email,name,gender,birthday"}]
                 startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

}
}

Answer 1

Give the Permission of user_birthday in your code,

self.loginButton.publishPermissions = @[@"basic_info", @"email", @"user_friends",@"user_birthday"];

Without above permission in V 2.4 you get only name and id from facebook,

Check Facebook developer site Graph Exploror

Without permission of user_birthday , got an error,
