Setting the username to Facebook name with Parse API. - ios

Question

Currently here is my code in my LogInViewController that contains the handler for Facebook signup process and code that I was hoping would setup the username and email address to their Facebook Name and Email address.
- (IBAction)fbButtonPressed:(id)sender
{
NSArray *permissions =#[#"public_profile", #"email", #"user_friends"];
[PFFacebookUtils logInWithPermissions:permissions block:^(PFUser *user, NSError *error) {
if (!user) {
NSLog(#"Uh oh. The user cancelled the Facebook login.");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Log In Error" message:#"Uh oh. The user cancelled the Facebook login." delegate:nil cancelButtonTitle:nil otherButtonTitles:#"Dismiss", nil];
[alert show];
} else if (user.isNew) {
NSLog(#"User signed up and logged in through Facebook!");
FBRequest *request = [FBRequest requestForMe];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if (!error){
NSDictionary *userData = (NSDictionary *)result;
NSString *facebookID= userData[#"ID"];
NSURL *pictureURL = [NSURL URLWithString:[NSString stringWithFormat:#"https://graph.facebook.com/%#/picture?type=large&return_ssl_resources=1", facebookID]];
NSMutableDictionary *userProfile = [NSMutableDictionary dictionaryWithCapacity:7];
if (facebookID){
userProfile[#"facebookID"] = facebookID;
}
if (userData[#"name"]) {
user.username = userProfile[#"name"];
}
if (userData[#"email"]){
user.email = userData[#"emai"];
}
[user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error){
NSLog(#"ERROR: %# %#", error, [error userInfo]);
}else{
[self.navigationController popToRootViewControllerAnimated:YES];
}
}];
}
}];
} else {
NSLog(#"User logged in through Facebook!");
[self.navigationController popToRootViewControllerAnimated:YES];
}
}];
}

Answer 1

You have a typo in
user.email = userData[#"emai"];
Also, for the name, you try getting the name from userProfile:
if (userData[#"name"]) {
user.username = userProfile[#"name"];
}
which should be
if (userData[#"name"]) {
user.username = userData[#"name"];
}

Answer 2

Try this.
PFUser *user = [PFUser currentUser];
FBRequest *request = [FBRequest requestForMe];
[request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSLog(#"test");
if(!error) {
NSDictionary *userData = (NSDictionary *)result;
NSString *name = userData[#"name"];
user.username = name;
NSLog(#"user:%#", name);
[user saveEventually];
} else {
NSLog(#"An error occurred: %#", error.localizedDescription);
}
}];
