iOS Build a Self-Destructing Message iPhone App Retrieving and Viewing Data from Parse.com Retrieving Data from Parse.com

tableview dont update with retrieved messages

hi guys,

here another issue, i ve implemented retrieving data from parse.com , ive still an issue whereby i cant share pictures while sharing a video is not a problem (see my another discussion)...

when i share a video, i see at the back end Parse that it is saved. when i want to retrieve, i see in the nslog that the retrieved messages are 3 (this is right).

when I run the app, i dont see anything in the inbox, which means that tableview dont update/show retrieved messages.

here is my inboxvc.m:

@implementation InboxTableViewController



- (void)viewDidLoad
{
    [super viewDidLoad];

    PFUser *currentUser = [PFUser currentUser];
    if (currentUser) {
        NSLog(@"Current user: %@", currentUser.username);
    }

    else {

    [self performSegueWithIdentifier:@"showLogin" sender:self];
    };

}


-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    PFQuery *query = [PFQuery queryWithClassName:@"Messages"];
    [query whereKey:@"RecipientIDs" equalTo:[[PFUser currentUser]objectId]];
    [query orderByDescending:@"createdAt"];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {

        if (error) {
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }

        else {
            // we found messages
            self.messages = objects;
            [self.tableView reloadData];
            NSLog(@"Retrieved %d messages", [self.messages count]);
        }
    }];
}

I made a typo in

"cell.textLabel.text = [message objectForKey:@"senderNameR"];

senderNameR => senderName
