Ribbit, highlight recipient state not going

Hi,

Going through the recipient stage of sending files and I've noticed in the app that when I select a recipient to send a file to it stays highlighted?

Also I'm getting these errors in the console

2014-01-24 10:59:28.340 Ribbit[4099:60b] Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

youve got to deselect the cell programtically in your didSelectRowAtIndexPath method

[tableView deselectRowAtIndexPath:indexPath animated:YES];

as for the snapshot errors...they dont really make sense. Snapshots capture images of your actual views, sort of like a programmatic screen shot. But the ribbit app does not use snapshots anywhere. They are not the same as taking a picture using the image picker. Im not sure where those are coming from

I already have this in the code and it still doesn't de-select :/

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];

    PFUser *user = [self.friends objectAtIndex:indexPath.row];

    if (cell.accessoryType == UITableViewCellAccessoryNone) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        [self.recipients addObject:user.objectId];
    } else {
        cell.accessoryType = UITableViewCellAccessoryNone;
        [self.recipients removeObject:user.objectId];
    }
}
