pushViewController：detail not push detailView

Question

私のアプリはビューを完全にナビゲートしていました。さて、私は理解できない何らかの理由で、私のdetailViewはモーダルビューのpushViewController:detailメソッドでは表示されません。

なぜそれがもう機能していないのかわかりません。どんな助けもありがとう。ありがとう。

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


      [tView deselectRowAtIndexPath:indexPath animated:YES]; 

      if(indexPath.row == 0){ 
       NSLog(@"hey"); 
       DetailView * detail = [[DetailView alloc] initWithNumber:indexPath.row]; 
       detail.delegate = self; 
       [[self navigationController] pushViewController:detail animated:YES]; 
      } 

      if(indexPath.row == 1){ 
       NSLog(@"hey"); 
       DetailView * detail = [[DetailView alloc] initWithNumber:indexPath.row]; 
       detail.delegate = self; 
       [[self navigationController] pushViewController:detail animated:YES]; 
      } 

      if(indexPath.row == 2){ 
       NSLog(@"hey"); 
       DetailView * detail = [[DetailView alloc] initWithNumber:indexPath.row]; 
       detail.delegate = self; 
       [[self navigationController] pushViewController:detail animated:YES]; 
      } 

      if(indexPath.row == 3){ 
       NSLog(@"hey"); 
       DetailView * detail = [[DetailView alloc] initWithNumber:indexPath.row]; 
       detail.delegate = self; 
       [[self navigationController] pushViewController:detail animated:YES]; 
      } 

      if(indexPath.row == 4){ 
       NSLog(@"hey"); 
       DetailView * detail = [[DetailView alloc] initWithNumber:indexPath.row]; 
       detail.delegate = self; 
       [[self navigationController] pushViewController:detail animated:YES]; 
      } 



     } 

はここでクラスコードです：

は、ここでの方法です。私はmodalViewとnavigationControllerに渡す必要がある場合ではないと確信している：

Answer 1

あなたは、デバッグとあなたのnavigationControllerがnilでないことを確認しましたか？

Answer 2

私はそれを理解しました。私は間違って私のrootViewControllerのメソッドinsertNewObjectを消去しました。私が書き直したとき、私はModalView * modal = [[ModalView alloc] init];に追加するのを忘れていました。それが問題でした。ここで

メソッドは、それが働いていることを今のようになります。

- (void)insertNewObject { 

    ModalView * modal = [[ModalView alloc] init]; 
    UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:modal]; 

    [self presentModalViewController:controller animated:YES]; 

}
