Question

I have UITableView with Custom View on it.
For the bottom of the tableview, I add a “Load More” cell there.
After clicked, the tableview load more data successfully and the “Load More” cell still at the bottom of the tableview.
However, after I clicked the first “Load More”, the second “Load More” appears, and the custom view still exist in the same cell of second “Load More”. “Load More” and custom view are on the same cell. I want that cell only appear “Load More”.

This problem exists for the third, fourth “Load More”.
Can anyone help me?

Answer 1

I think you should use 2 different identifiers, one for the normal cell and one for load more cell.

And one thing is that creating custom cell should be done in the block.

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

    //  create the views in side the cell and add it
    ...
}

Then outside this block, update the cell.
You can set the tag for your views in the creation of cell, and update the corresponding view by getting it with [cell.contentView viewWithTag:tag]
