After creating custom tableView: tableView content is not showing/views are moving around like crazy

I am trying to program a view which has a tableView contained within it.

After creating custom tableView, instead of just customising the delegate in the viewController implementation, I have come across a problem whereby the cells do not populate. This tableView is the beginning of a messages panel, so at the bottom there is a text view. When I click the text view, I had it so that the whole view would resize so that nothing gets lost behind the keyboard. Now this doesn't seem to work either.

This is my cellForRowAtIndexPath code: 

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    static NSString *CellIdentifier = @"Cell";
    messageCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    NSArray *listOfMessages = [self.infoObject objectForKey:@"eventMessages"];
    NSDictionary *message = [listOfMessages objectAtIndex:(indexPath.row)];

    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
    NSDateComponents *dateComponents = [calendar components:NSCalendarUnitDay | NSCalendarUnitHour | NSCalendarUnitMinute fromDate:[message objectForKey: @"sendDate"]];

    cell.messageContentLabel.text = [message objectForKey:@"messageContent"];
    [cell.messageContentLabel sizeToFit];
    cell.dateLabel.text = [NSString stringWithFormat:@"%ld %ld:%ld",(long)[dateComponents day], (long)[dateComponents hour], [dateComponents minute]];
    cell.senderLabel.text = [message objectForKey:@"senderName"];

    return cell;
}

The 'infoObject' is a property of the custom tableView's class and is assigned in viewDidLoad of the root view... All of the above code is contained in the .m file for the custom view. The view is linked up to a tableView in the storyboard.

If anyone has had this problem, or knows what I am missing, then please advise! I really appreciate any help, been stuck with this all day! Cheers!

Could it be due to the delegate/datasource not properly being set to self? I know that when you want to override in the main viewcontroller you have to set delegate & datasource to self. Do you have to explicitly do that when creating a UTableView subclass?

okkkkkk so the issue was down to not setting the initialisation methods for the custom tableView!!! Yaaayyyy. Why does that need to be done? there is no explicit indication to do it.. do these methods instantly get run when the compiler finds the class in the storyboard or something?
