UI レイアウトをデバッグしようとしていますが、コードに追加したすべての要素に [self.element setTranslatesAutoresizingMaskIntoConstraints:NO]; というラベルが付いています。XIB ファイルで設定される唯一のものは、ビューの背景色です (タブ付きの viewController.
NSLog を見ると、次のように表示されます。

po コマンドからわかるように、NSAutoresizingMasktLayoutContraints を取得しています。これはあってはならないことだと思いましたか?
これを取得しないようにするにはどうすればよいですか?
