How to send an array to a table where the user can select a friend and post to their Facebook wall

问题

I'm using the following code to call the Facebook request method, the request calls the delegate method which returns an NSDictionary object with a key labelled 'data'. I then get the friends array by calling NSArray *data = [result objectForKey:@"data"];

Then the code loops through that array and extracts the names outputting them to the console.

The problem I'm having is how do I send this array to a table where the user can select a friend and post to their FB wall.

thanks for any help :)

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

[[delegate facebook] requestWithGraphPath:@"me/friends" andDelegate:self];


// get the array of friends                
NSArray *data = [result objectForKey:@"data"];

NSMutableArray *array = [NSMutableArray array];    
                for (int i = 0; i < data.count; i++){
                    id object = [data objectAtIndex:i];
                    [array addObject:[object objectForKey:@"name"]];
                }

// output the array of friends
NSLog(@"list of friends %@", array);

I'm thinking I need something like (I'm not sure what to put in the objectAtIndex:????? part:

[self apiDialogFeedFriend:[[data objectAtIndex:**?????**] objectForKey:@"id"]];

and then

 [self apiGraphFriends];

get Facebook friends photo and name . Stroe in array

    FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
                                              NSDictionary* result,
                                              NSError *error) {
    friends = [result objectForKey:@"data"];
    arr_FaceBookFriendProfileImg = [[NSMutableArray alloc] init];
    arr_FaceBookFriendName = [[NSMutableArray alloc]init];


    for (NSDictionary<FBGraphUser>* friend in friends) {

        NSString *str_FacebookFriendNames;
        str_FacebookFriendNames = friend.name;
        NSString *userPhotoUrl = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?", friend.id];
        NSURL *url_FriendProfileImage = [NSURL URLWithString:userPhotoUrl];


        [arr_FaceBookFriendName addObject:str_FacebookFriendNames];
        [arr_FaceBookFriendProfileImg addObject:url_FriendProfileImage];

    }
  //  [table_facebookFriends reloadData];
}];

and display the TableView

      cell.lbl_FriendsProfileName.text = [arr_FaceBookFriendName objectAtIndex:indexPath.row];
