UITableView won't refresh after reloadData

[chuck]

I'm making an app which will shuffle cards and then display them in a table view. I want to provide a refresh button in the navigation bar, so that users can update the list with a new set of shuffled cards. I started the project with the Utility Application template and have put pretty much all of the logic of the app in the MainViewController.m file which I plan to refactor out later into individual object files.

When I click Refresh, it runs the refresh action which shuffles the cards and then runs [self.tableView reloadData] and even accesses

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

for each table row since I have it print out an NSLog statement each time this is run. It even changes the textLabel.text of each cell which I've also verified with an NSLog statement right after changing it.

I've tried [self.tableView setNeedsDisplay] and [self.view setNeedsDisplay] and nothing will refresh the screen! I've looked around different forums and can't see any solution to this. Could anyone please push me in the right direction?

Maybe the problem IS the cellForRowAtIndexPath method. Check your creation/release of the TableViewCell, maybe the error is in there. Start with a simple cellForRowAtIndexPath method then add your addSubview calls or whatever.

Thanks for the advice, but I don't think that can possibly be the issue, because I just use the boilerplate method for that:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	
    static NSString *CellIdentifier = @"MenuItem";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }
	
	NSUInteger row = [indexPath row];
	cell.textLabel.text = [playCards objectAtIndex:row];
	NSLog( @"Card: %@", cell.textLabel.text );
	
    return cell;
}

Will you be able to send us your program, because "reloadData" should be enough to refresh your tableView, there's no need for setNeedsDisplay or other. I have tried it a couple of times now and it is working for me.

So, it's always the stupid stuff, right? I discovered that my main view was also a UITableView, so I had two table views on top of each other! No wonder it didn't work. Anyway, thanks for trying to help, there's no way you could've figured that out.

Did the UITableView reload correctly in the simulator? I am using 3.1.3 jailbroken iphone. Mine UITableView reloads in the simulator. But it does not reload in the real iphone.

Any ideas?

If you are making the change in cellForRowAtIndexPath, then perhaps the call:

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

is not returning nil (i.e. the cell already exists), in which case the code making the mod will not be executed
