[removeAllObjects] doesn't work

After i cancel sending, i go back to Camera tab but i find the recipients still checked. No Errors.

- (IBAction)cancelButton:(id)sender {
    self.image = nil;
    self.videoFilePath = nil;
    [self.recipients removeAllObjects];
    [self.tabBarController setSelectedIndex:0];
}

I don't have my code for this project in front of me and wont for a couple hours, but if I remember correctly you need to also set the accessoryView to none.

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];

    UITableViewCell *cell = [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];

    }

}

I did that.
