My applications paymentWindowРяды перезапись друг друга в UITableView Swift
Эй у меня возникли некоторые проблемы с UITableView в Swift 3.0, которые перезапись мои настройки страницы, когда я прокрутки.
Я использую пользовательский UITableViewCell для определения информации о строках.
Кто-нибудь знает эту проблему?
Моя текущая настройка выглядит так.

Эй Роб, спасибо за разъяснение. Я попробую это. Будет ли это также устранять проблему с заполнением ячейки друг на друга, как видно на моем снимке экрана? – Joachimdj
Да, если вы правильно спроектировали ячейки прототипа, он должен решить эту проблему. – Rob
