Custom login with facebook button. Not getting info other than name and UserID - objective-c

Question

I'm trying to get email from my logged in user using Facebook SDK. Here are 2 of my login methods
-(void)loginButtonClicked {
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithReadPermissions: #[#"public_profile", #"email", #"user_friends"]
fromViewController:self
handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
NSLog(#"Process error");
} else if (result.isCancelled) {
NSLog(#"Cancelled");
} else {
[self getFBUSerData];
NSLog(#"Logged in");
}
}];
}
- (void) getFBUSerData {
if (FBSDKAccessToken.currentAccessToken != nil) {
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"me" parameters:nil]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"fetched user:%# and Email : %#", result,result[#"email"]);
}
}];
}
}
The result in the log:
(lldb) po result
{
id = 42357***4506554;
name = "Fname Lname";
}
But no email or friends list. Any help how to get those?

You have to assign the parameters you need to get in getFBUserData().
Something like this:
- (void) getFBUSerData {
if (FBSDKAccessToken.currentAccessToken != nil) {
NSDictionary *dict = [[NSDictionary alloc] initWithObjects:#[#"id, name, first_name, last_name, picture.type(large), email"] forKeys:#[#"fields"]];
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"me" parameters:dict]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
NSLog(#"fetched user:%# and Email : %#", result,result[#"email"]);
}
}]; }
}
