Я столкнулся с какой-то странной проблемой: когда контроллер представления представлен в popover, диспетчеры представления представления view не привязаны к нижнему краю его супервизора, в этом случае сам window.
Код AppDelegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let window = UIWindow(frame: UIScreen.main.bounds)
window.rootViewController = UIStoryboard(name: "NavigationController", bundle: Bundle.main).instantiateInitialViewController()
window.makeKeyAndVisible()
window.backgroundColor = .yellow // Needed to detect the issue.
self.window = window
return true
}

Скопируйте все внутри нового проекта, удалите main в качестве основной раскадровки для запуска.
- Запустите проект на симуляторе iPhone X Plus (или реальном устройстве).
- Нажмите на нижнюю часть, чтобы отобразить контроллер представления. 2.1. Включить замедление (только для симулятора).
- Поверните устройство.
Проблема, о которой я говорю, - это когда отображается желтый view (window). Один поворот корректно отображает контроллер представления, другой начинается в неправильном состоянии.
Является ли это ошибкой, что у моей раскадровки есть что-то от UIKit?
Обновление: В проекте используется последний IOS SDK и устаревшие API (как показано выше, "почти все построено с IB" ).
Обновление 2:. Я обновил исходное предложение, чтобы было ясно, что он не a UIPopoverController.
