Question

I’m getting a weird issue. I have a custom UITableViewCell and each cell has a UIButton and UITextField. When the button is clicked, it changes the textfield value to some constant.

Now in the cellForRowAtIndexPath method I have this:

    folderTitleTextView.tag=indexPath.row;
    [arrayOfTextFields insertObject:folderTitleTextView atIndex:indexPath.row];
    NSLog(@"indexpath.row:%i", indexPath.row);
    NSLog(@"text fields count %i", [arrayOfTextFields count]);

So if I have two cells, then every time I reload the table, it adds two more objects to the arrayofTextFields, even though it should replace the existing ones. So if I have two cells and I reload the table 3 times, then for some reason arrayOfTextFields count is 8.

Answer 1

This folderTitleTextView.tag=indexPath.row; is not a good idea because everything starts with a tag of 0, so when accessing views with viewWithTag:0 or when setting up the row 0, you will get weird results.

I would suggest also checking the number of items in arrayOfTextFields and use [arrayOfTextFields replaceObjectAtIndex:indexPath.row withObject:folderTitleTextView]; or [arrayOfTextFields insertObject:folderTitleTextView atIndex:indexPath.row]; depending on the current count for arrayOfTextFields

Try this:

folderTitleTextView.tag = (indexPath.row + 100);
if ([arrayOfTextFields count] <= indexPath.row) {
    [arrayOfTextFields insertObject:folderTitleTextView atIndex:indexPath.row];
} else {
    [arrayOfTextFields replaceObjectAtIndex:indexPath.row withObject:folderTitleTextView];
}
NSLog(@"indexpath.row:%i", indexPath.row);
NSLog(@"text fields count %i", [arrayOfTextFields count]);
