ACAccount 无法识别的选择器发送到实例（NSInvalidArgumentException）

Question

我选择了一个现有帐户。我想通过另一个viewController这个选定的帐户。但是我得到了这个错误 --> "Unrecognized selector sent to instance"

这是我的代码：

在tableView上选择帐户：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    AccountsTableViewCell *selectedRow = [self.accountTable cellForRowAtIndexPath:indexPath];
    choosenAccount = selectedRow.twitAccount;
     [self performSegueWithIdentifier:@"selectAccount" sender: nil];

}

转场：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"selectAccount"]) {
         TwitterFollowersViewController *vc = (TwitterFollowersViewController *) segue.destinationViewController;
        vc.twitterAccount = choosenAccount;
    }
}

ViewController.h文件：

@interface TwitterFollowersViewController : UIViewController
      @property (retain, nonatomic) ACAccount *twitterAccount;
@end

检查情节提要中的类名，我认为它是 UIViewController 而不是 TwitterFollowersViewController。
