Force UITableView to call cellForRowAtIndexPath: for all cells

Question

I am having some trouble with UITableView's reloadData method. I have found that it only calls cellForRowAtIndexPath if there are new cells being added or taken away.

Example: I have five cells, each containing five strings. If I add a new cell and call reloadData, the table is updated and I see it. Yet if I go into one of the five cells, add a new string, then return and call reloadData, none of the table view's delegate methods is called.

My question: Is it possible to force the table view to completely reload the data in all of its visible cells?

Answer 1

I found the problem- I had my cell customization code in the if(cell == nil) block, so because the cells were being recycled, they weren't being changed. Taking my customization code out of that block fixed the problem.

Answer 2

I've found that reloading sections reloads data more readily. If you just have one section you can try:

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationNone];

Answer 3

You can try this

[tableView reloadData];

or

[tableView deleteRowsAtIndexPaths:[NSMutableArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationFade];

put this in commitEditingStyle method.
