How to update a cell in a UITableView?

Question

I'm using Delegate methods to get data from child view and want to dynamically edit my table in the root view.

So I would like to do something like this in my viewWillAppear method :

[myTable setCell:newCell atIndex:i];

What should I do ? Thanks a lot

put your code in between:

[myTable beginUpdates];
//your code
[myTable setCell:newCell atIndex:i];
//your code end
[myTable endUpdates];

Well, finally I made it using :

[cellules beginUpdates];
[cellules reloadData];
[cellules endUpdates];

I used reloadData because it's a little TableView (3 cells), for big TableViews this should be better :

– reloadRowsAtIndexPaths:withRowAnimation:

Thanks anyway !

Glad you figured it out! If the cell is visible, you can also call `cellForRowAtIndexPath:` on the table view and then modify the properties or contents of that cell -- you might notice that some of the Xcode project templates use this approach. – rickster May 27 '12 at 20:30
Yep, I used reloadData because I've a small Table View (only 3 cells), but of course I should use cellForRowAtIndexPath. Thanks ! – Rob May 27 '12 at 20:46
