Два PickerViews selectTypeOfWorkChoices
& selectLocationChoices
отображаются некорректно.
Функция dismissPickerView () работает нормально. Однако другая функция " createPickerView ()" имеет некоторые проблемы. Хотя появляется UIpickerviews
, я не вижу вариантов в UIPickerViews
и не знаю почему.
Может кто-нибудь помочь мне выяснить, что не так с моим кодом, пожалуйста?

}
