Question

like build in apple notes app, after you swipe to delete the selected row, it will select the nearest available row automatically.

The logic should be:

if row count > 0 then
if deleted_row == last row then
select deleted_row_index-1 row
else
select deleted_row_index+1 row
end
end

i have try to implement the above logic in the commitEditingStyle event, but the selection fail.
the selectRowAtIndexPath logic just don’t work in this event, if i apply it in a button, it works.

any idea?

One way to solve this is to use the method performSelector:withObject:afterDelay:.

From within the tableView:commitEditingStyle:forRowAtIndexPath: you can:

NSIndexPath *indexPathToSelect = ...
[self performSelector:@selector(selectRowAtIndexPath:) 
           withObject:indexPathToSelect
               afterDelay:0];

Then define the selectRowAtIndexPath: method in your view controller

- (void)selectRowAtIndexPath:(NSIndexPath *)indexPath {
  [self.tableView selectRowAtIndexPath:indexPath 
                              animated:YES 
                        scrollPosition:UITableViewScrollPositionTop];
}
