Я хочу получить звездный рейтинг для опроса о производительности труда с использованием UITableView и Cosmos. Моя проблема в том, что я совершенно не понимаю, как я могу получить доступ и сохранить рейтинг, который пользователь дает для каждой строки.
Может кто мне поможет! :) Это то, что у меня есть ... Я пробовал так много разных возможностей, но всегда терпел неудачу. Я установил начальный рейтинг элементов на 0, который затем должен обновляться, как только пользователь оценит его, и в конечном итоге полностью сохраняется в Firebase, когда пользователь нажимает «сохранить»
