Fetch User Profile Picture from new Facebook sdk 4 in ios

Question

I am developing an App in Which I have implemented Facebook now I want to fetch Facebook user profile picture and Birthday in my app. I searched into net but all tutorials are 2 or 3 years old.

I have set permission like..

 loginButton.readPermissions=@[@"public_profile", @"email", @"user_friends",@"user_birthday",@"user_location"]; 

and fetching with codes

if ([FBSDKAccessToken currentAccessToken]) {
            [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:nil]
             startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                 if (!error) {
                     NSLog(@"fetched user:%@", result); 
} 

but the output is

  fetched user:{
email = "XYZ@gmail.com";
"first_name" = XYZ;
gender = male;
id = xxxxxxxxxxx;
"last_name" = ABC;
link = "https://www.facebook.com/app_scoped_user_id/xxxxxxxxx/";
locale = "en_GB";
name = "XYZ ABC";
timezone = "5.5";
"updated_time" = "2015-04-08T06:57:20+0000";
verified = 1;

}

Why i not getting birthday and profile picture information?

Answer 1

As Ashish mentioned, initWithGraphPath:@"me" parameters:nil does not return the profile_pic (or birthday) unless explicitly requested through initWithGraphPath:@"me" parameters:@{@"fields": @"picture, birthday"}

Be careful though, when parameters are not nil, it only returns the requested fields, so you won't get name, gender, etc unless you add them to the parameters explicitly as well
