iOS Table View Refresh Cell
You can call [self.tableview reloadData];
on the tableview and refresh the entire table.
Otherwise you can do this to refresh a single cell.
[self.tableView beginUpdates];
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPathOfYourCell] withRowAnimation:UITableViewRowAnimationNone];
[self.tableView endUpdates];
Since you already have indexPath of the cell, sometimes this may just do the job
UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
[cell reloadInputViews];
