if ([FBSDKAccessToken currentAccessToken]) {
    [[[FBSDKGraphRequest alloc] initWithGraphPath:@"me" parameters:@{ @"fields" : @"id,name,picture.width(100).height(100)"}]startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
        if (!error) {
            NSString *nameOfLoginUser = [result valueForKey:@"name"];
            NSString *imageStringOfLoginUser = [[[result valueForKey:@"picture"] valueForKey:@"data"] valueForKey:@"url"];
            NSURL *url = [[NSURL alloc] initWithURL: imageStringOfLoginUser];
            [self.imageView setImageWithURL:url placeholderImage: nil];
        }
    }];
}
