Обозначает ли презентацияViewController с представленнымViewController

Question

Моя настройка проекта поддерживает как портретную, так и альбомную ориентацию. Тем не менее, я хочу, чтобы один из представленных контроллеров представлений (например, контроллер вида A) мог поворачиваться. Я использую

override func shouldAutorotate() -> Bool { 
    return false 
} 

override func supportedInterfaceOrientations() -> Int { 
    return Int(UIInterfaceOrientationMask.Portrait.rawValue) 
} 

, чтобы отключить вращение в других контроллерах. Оно работает. Однако, когда А представлены модальна и вращают, контроллер вида Предъявления (скажем, вид контроллер B) отчеты:

    Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.

я использую Автокомпоновку в B, и я не хочу его вращаться. Я сделал несколько экспериментов, и эти ошибки ограничения - это те же ошибки, что и при повороте. Я подозреваю, что B также вращается, но он невидим.

Меня беспокоила эта проблема в течение нескольких дней. Я действительно хочу знать, почему это произошло и как решить эту проблему?

Answer 1

Возможно, this ответ может вам помочь.

Котировка (четвёртая абзац ответа):

[...] Раствор два UIWindow сложены друг на друга, каждый вращающийся (или нет) с его собственной точки зрения корневой контроллер. [...]

(Примечание: третий абзац содержит основное сообщение объяснения).

Надеюсь, это поможет.
