Я создал приложение iOS, которое просто отправляет Location Coordinates на сервер после входа пользователя в систему. Я также реализовал виджет, который делает снимок местоположения, отображает его на экране виджета и отправляет его на сервер. Приложение простое. Я просто хочу через 20-30 минут открыть приложение или виджет на короткое время в фоновом режиме и отправить местоположение на сервер.
Для этого я реализовал в приложении Background Fetch. Работает во время симуляции от отладчика. Но не будет работать на реальном iOS устройстве. Код приложения ниже.
Если есть какое-либо другое решение для выполнения такой задачи, сообщите мне, кроме Push/Remote Notifications. Спасибо
