項目が通知される回数に応じて、NSDateComponents を使用して通知ごとに異なる時間を設定している uilocalnotification があります。

これらの時間を NSUserDefaults に保存して、ユーザーが必要に応じて時間を変更したい場合は、それらの時間を NSUserdefaults に保存したいと考えています。デフォルトの NSuserdefaults を userupdatednsuserdefaults に置き換えたい..datepicker でセグメント化されたコントロールがあるため、ユーザーが datepicker から時間を選択すると、その時間がデフォルトの nsuserdefaults に更新されます。

オーバーライドせずにNSDateをNSUserDefaultsに保存できます。この質問については、こちらで詳しく説明しています。NSUserDefaults に NSDate を格納する最適な方法は何ですか? .

日付の NSUserDefault 配列に格納することもできます。したがって、標準の UserDefaults をオーバーライドすることは良い考えではないと思います。代わりに、カテゴリ拡張を作成して、より抽象化を実現できます。
