This is the method to get user profile picture:

//in your app delegate file configure "FBProfilePictureView" class
- (void)applicationDidFinishLaunching:(UIApplication *)application {    
    [FBProfilePictureView class];
}

//in your header file
IBOutlet FBProfilePictureView   *userPictureView;


@property (strong, nonatomic) FBProfilePictureView     *userPictureView;

//here "userPictureView" is uiview not uiimageview

//in your .m file 

-(void)setProfilePicture {
    [FBSession.activeSession closeAndClearTokenInformation];

    NSArray *permissions = [NSArray arrayWithObjects:@"email", nil];

    [FBSession openActiveSessionWithReadPermissions:permissions
                                       allowLoginUI:YES
                                  completionHandler:
     ^(FBSession *session,
       FBSessionState state, NSError *error) {
         NSLog(@"\nfb sdk error = %@", error);
         switch (state) {
             case FBSessionStateOpen:
                 [[FBRequest requestForMe] startWithCompletionHandler:
                  ^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
                      if (!error) {

                          self.userPictureView.profileID = [user objectForKey:@"id"];

                      } 
                  }];
                 break;
             case FBSessionStateClosed:
                 //need to handle
                 break;
             case FBSessionStateClosedLoginFailed:
                 //need to handle
                 break;
             default:
                 break;
         }
     }];
}

in your .h

#import<FacebookSDK/FacebookSDK.h>

Now in Your .m file just call below method to get user data

-(void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user{
    NSLog(@"usr_id::%@",user.id);
    NSLog(@"usr_first_name::%@",user.first_name);
    NSLog(@"usr_middle_name::%@",user.middle_name);
    NSLog(@"usr_last_nmae::%@",user.last_name);
    NSLog(@"usr_Username::%@",user.username);
    NSLog(@"usr_b_day::%@",user.birthday);

  }

Above method is defined in FBLoginView.h you can see there.

This method i have added According to latest facebookSDK.framework.Hope it will help you.

I find it works best if you write the completion handler to treat the result as a FBGraphObject:

[[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, FBGraphObject *result, NSError *error) {
  if (result && !error) {
    name = result[@"name"];
    email = result[@"email"];
    facebookId = result[@"id"];
  } else {
    NSLog(@"Error!");
  }
}];
