Getting user's Personal info from Facebook in iOS

Question

I am quite new to objective-C and iPhone Development environment.

I am implementing Facebook login in my app to get User's name, Email and profile Picture. I have successfully implemented login Part and have received name and User ID of the person.

Now i want to get User's Email and Profile Picture from Facebook.But i am not having any Idea how to get it.I am using Facebook IOS SDK v4.0.

How can i fetch User's Profile picture and Email Id from Facebook when i am having User ID?

@Shruti That's Ok i already tried implementing this link, but i got only first name and last name and no provision for getting Email ID — Simer Sarao, Apr 06 '15 at 12:27
@SimerSarao i don't know how your are implementing that. I used the same code and i was getting email id too. Can you share your code for more clarity — Shruti, Apr 06 '15 at 12:37

To get user Email ID you must ask permission for email while logging.

FBSDKLoginButton *loginView = [[FBSDKLoginButton alloc] init];
loginView.readPermissions =  @[@"email"];
loginView.frame = CGRectMake(100, 150, 100, 40);
[self.view addSubview:loginView];

You can get user email Id in New SDK using GraphPath.

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

             if (!error) {
                 NSLog(@"fetched user:%@  and Email : %@", result,result[@"email"]);
         }
         }];
    }

result would get you all the user Details and result[@"email"] would get you the email for logged in user.

To get Profile picture you can use

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=normal",result[@"id"]]];
NSData  *data = [NSData dataWithContentsOfURL:url];
_imageView.image = [UIImage imageWithData:data];

or u can also use FBSDKProfilePictureView to get profile Picture by passing user profile Id:

FBSDKProfilePictureView *profilePictureview = [[FBSDKProfilePictureView alloc]initWithFrame:_imageView.frame];
[profilePictureview setProfileID:result[@"id"]];
[self.view addSubview:profilePictureview];

Refer to :https://developers.facebook.com/docs/facebook-login/ios/v2.3#profile_picture_view

or u can also get both by passing as parameters

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"me"
                                           parameters:@{@"fields": @"picture, email"}]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error) {
                 NSString *pictureURL = [NSString stringWithFormat:@"%@",[result objectForKey:@"picture"]];

                 NSLog(@"email is %@", [result objectForKey:@"email"]);

                 NSData  *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:pictureURL]];
                 _imageView.image = [UIImage imageWithData:data];

             }
             else{
                 NSLog(@"%@", [error localizedDescription]);
             }
         }];

hi dheeraj i tried this but i am getting null in my email. – Simer Sarao Apr 07 '15 at 09:10
You must ask permission for email while logging. – Dheeraj Singh Apr 07 '15 at 09:11
i have done FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init]; loginButton.center = self.view.center; [self.view addSubview:loginButton]; self.loginButton.readPermissions = @[@"public_profile", @"email"]; in my viewDidLoad – Simer Sarao Apr 07 '15 at 09:13
is your email address verified ? – Dheeraj Singh Apr 07 '15 at 09:14
verified means ? yeah i have successfully logged in – Simer Sarao Apr 07 '15 at 09:19
where can i get result of the above i.e where can i read the name,email . i.e function name where i will get user profile – Simer Sarao Apr 07 '15 at 09:36
could you just try asking permission for email and not public_profile? like this self.loginButton.readPermissions = @[@"email"]; – Dheeraj Singh Apr 07 '15 at 12:19
what change you made? – Dheeraj Singh Apr 07 '15 at 12:58
Hi i made the Change specified by you in above comment – Simer Sarao Apr 08 '15 at 04:30

Sorry for this messy answer, this is my first answer ever. You can use FBSDK Graph request to fetch user's all profile infos and FBSDKProfilePictureView class to fetch user's Profile Picture easily.This code is for manually Facebook login UI.

Firstly, you must put this code where login process start:

 FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];

[login logInWithReadPermissions:@[@"public_profile", @"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {

    if (error)
    {

     // There is an error here.

    }
    else
    {
        if(result.token)   // This means if There is current access token.
        {    
            // Token created successfully and you are ready to get profile info
            [self getFacebookProfileInfo];
        }        
    }
}];

And If login is successfull, implement this method to get user's public profile;

-(void)getFacebookProfileInfos { 

FBSDKGraphRequest *requestMe = [[FBSDKGraphRequest alloc]initWithGraphPath:@"me" parameters:nil];

FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];

[connection addRequest:requestMe completionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {

      if(result)
      {            
        if ([result objectForKey:@"email"]) {

          NSLog(@"Email: %@",[result objectForKey:@"email"]);

        }
        if ([result objectForKey:@"first_name"]) {

          NSLog(@"First Name : %@",[result objectForKey:@"first_name"]);

        }
        if ([result objectForKey:@"id"]) {

          NSLog(@"User id : %@",[result objectForKey:@"id"]);

        }

      }

 }];

[connection start];

Get current logged in user's profile picture:

FBSDKProfilePictureView *pictureView=[[FBSDKProfilePictureView alloc]init];

[pictureView setProfileID:@"user_id"];

[pictureView setPictureMode:FBSDKProfilePictureModeSquare];

[self.view addSubview:pictureView];

You must add refreshing code to your viewDidLoad method:

   [FBSDKProfile enableUpdatesOnAccessTokenChange:YES];

I use custom Facebook Login button in my project. So "facebookLoginButtonTouched" is my custom login button's "touched up inside" method. I am now editing my answer. — Mustafa Sait Demirci, Apr 07 '15 at 08:55
Most relevant answer in this thread. Far from Messy. Thanks dude! — Abhishek Arora, Jun 16 '15 at 08:20
'GET requests for /me should contain an explicit "fields" parameter' — Francisco Corrales Morales, Sep 15 '15 at 02:00
Are you sure that `enableUpdatesOnAccessTokenChange:` __has__ to be added in the `viewDidLoad` method and not somewhere in `AppDelegate`? — Iulian Onofrei, Nov 10 '15 at 11:21
