Answer 1

A:

If you have the UITableViewController object, just call

[theTableViewController.tableView reloadData];

i tried doing that in the viewdidload method but it didn't work, maybe I have bigger issues?

`-viewDidLoad` will only be called once and you don't need `-reloadData` in that case. Do you mean `-viewDidAppear:`?

KennyTM 2010-02-20 06:22:14

probably, i tried it in viewdidload, viewwillappear, viewdidappear, nothing is working,

@nick: `-viewDidAppear:` with a colon. The colons are significant in ObjC.

Answer 2

+1 A:

If the controller in tab 2 is a UIViewController with a UITableView property set as an IBOutlet, do the following:

- (void)viewWillAppear:(BOOL)animated 
{
    [self.tableView reloadData];
}

If your view controllers are UITableViewControllers, then they already have tableView properties and perform the above behavior on their own. If you are creating your own tableView property on UITableViewControllers, then you are overriding behavior that is already there and probably breaking functionality.
