У моего приложения происходит сбой при открытии из состояния уничтожения через Push-уведомление .Это работает хорошо, если приложение уже запущено, но когда приложение убито, тогда, если получено какое-либо push-уведомление, и я нажимаю на него, оно вызывает сбой приложения.Я не нашел ни одной ошибки, может ли кто-нибудь помочь мне решить эту проблему?
Если я прокомментирую UNUserNotificationCenter код из didFinishLaunchingWithOptions в AppDelegate.swift, тогда приложение не будет аварийно завершено, но представление не будет загружено с уведомлением,Я отправляю URL в push-уведомлении и проверяю его не пустым, а затем загружаю как представление.
