Question

I have a custom UITableViewCell that seems to appear multiple times on my table before I even start scrolling. It seems dequeueReusableCellWithIdentifier isn’t working properly. Here’s my cell:

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

When I call reloadRowsAtIndexPaths: on my tableView, for some reason it doesn’t dequeue that cell and it recreates the new one. Then when I scroll back up and then down again, sometimes my first cell dequeues, sometimes the second cell dequeues. MyCustomCell is basically a textfield so depending on which one dequeues, the text has different data each time.

Is there something more I should be doing in my custom cell? Thanks in advance.

From the code you show, it looks as if you only set up your cell’s content when a new one is created. Since there’s no way of knowing which cell you’ll be given from the cache, you need to configure the cell whether it’s new or one that’s being re-used.
