Question

I have a view that adds another view on top in this manner:

- (void)showAreaEditView {

    NSLog(@"SHOWING AREA EDITOR VIEW");

    if (self.thisAreaEditorView == nil) {

        // Create View
        AreaEditorView *tmpViewController = [[AreaEditorView alloc] initWithNibName:@"AreaEditorView" bundle:nil];
        self.thisAreaEditorView = tmpViewController;
        [tmpViewController release];

        // Hide the back button
        self.thisAreaEditorView.navigationItem.hidesBackButton = YES;

    }

    self.thisAreaEditorView.myInspectionID = self.myInspectionID;
    self.thisAreaEditorView.loggedIn = loggedIn;
    self.thisAreaEditorView.loggedInGroup = loggedInGroup;

    // Slide view up

    [self.view addSubview:thisAreaEditorView.view];


    CGRect endFrame = CGRectMake(self.view.frame.size.width/2 - thisAreaEditorView.view.frame.size.width/2,
                                 self.view.frame.size.height/2 - thisAreaEditorView.view.frame.size.height/2, 
                                 thisAreaEditorView.view.frame.size.width, 
                                 thisAreaEditorView.view.frame.size.height);

    CGRect startFrame = endFrame; // offscreen source

    // new view starts off bottom of screen
    startFrame.origin.y += self.view.frame.size.height;
    self.thisAreaEditorView.view.frame = startFrame;

    // start the slide up animation
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:.6];   
    thisAreaEditorView.view.frame = endFrame; // slide in
    [UIView commitAnimations];

}

I’m sure you can just ignore the slide part, I feel the addSubview is relevant.

Then in thisAreaEditor I have the view with the table and buttons and such. UITableView delegate/datasource is going to File’s Owner as normal.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    NSLog(@"numberOfRowsInSection returning %d", [tableData count]);
    [tableData count];

}

This function numberOfRowsInSection returns 4

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

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    // Configure the cell...
    NSString *thisText =  [tableData objectAtIndex:indexPath.row];
    cell.textLabel.text = thisText;

    NSLog(@"looking at cell %d text:%@", indexPath.row, thisText);

    return cell;

}

But cellForRowAtIndexPath never gets called.

I’m at a loss here, I have no idea how it can seem to work fine but one of the delegate functions simply not be called.

I have tried [bigTable reloadData] and so on, the table just never gets populated and no logs from the function output.

Thanks in advance.

You might have just edited this out, if so I’m sorry, but it looks like you forgot to return tableData’s count.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    NSLog(@"numberOfRowsInSection returning %d", [tableData count]);
    return [tableData count];
}
