Question

I’m trying to change the accessory view of a UITableViewCell when its row is selected, I have the following code:

- (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell* cell = [self tableView:aTableView cellForRowAtIndexPath:indexPath];
    UIActivityIndicatorView *activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
    [activityView startAnimating];
    cell.accessoryView = activityView;
    [activityView release];
}

But this isn’t working. Any ideas?

Answer 1

You should not ask the tableview datasource (your self) for a cell. because this will create a new cell which is just not displayed.

replace

UITableViewCell* cell = [self tableView:aTableView cellForRowAtIndexPath:indexPath];

with

UITableViewCell *cell = [aTableView cellForRowAtIndexPath:indexPath];
