これまでのところ、新しいセルを追加するためのボタン付きの を作成しUITableViewました。HabitViewControlleセルをタップすると adetialViewControllerが表示されます。このビューでは、それらは でありtextField、タップするUIPickerと が起動されます。tableViewCellのタイトルをピッカー選択に設定したい..string呼び出しcellNameを行い、それを他の に送信できますViewController。また、pickerが変更されたcellNameときに、ピッカー選択が選択されたときにセルにしたいタイトルに文字列を設定するようにしました。したがって、cellNameが設定されているときに実際にセルのタイトルを文字列に設定し、ピッカーの選択が変更されたことを除いて、ほとんど準備ができています。これが意味をなさない場合は、私にコメントを送ってください。質問を言葉で書くのが難しいので、私は助けようとします
