모달로 표시 한 ViewController에서 ViewController를 표시 할 때 크래시

우리 프로덕션 응용 프로그램에는 모달로 표시된`ViewController에서 ViewController을 표시하는 충돌 보고서가 있습니다.모달로 표시 한 ViewController에서 ViewController를 표시 할 때 크래시

우리는 BackgroundForegroundDelegate입니다. 앱이 배경을 입력 할 때마다 현재 ViewController 위에 잠금 화면이 표시됩니다.

AppDelegate에 :

func applicationDidEnterBackground(_ application: UIApplication) { 
    backgroundForegroundDelegate?.applicationDidEnterBackground() 
} 

func applicationWillEnterForeground(_ application: UIApplication) { 
    backgroundForegroundDelegate?.applicationWillEnterForeground() 
}

LockScreenViewController :

lazy var lockScreenViewController = UIStoryboard(name: "Login", bundle: nil).instantiateViewController(withIdentifier: "LockScreenViewController") 

func applicationDidEnterBackground() { 
    let visibleViewController = (self.selectedViewController as? UINavigationController)?.visibleViewController 
    (visibleViewController as? BackgroundForegroundDelegate)?.applicationDidEnterBackground() 

    lockScreenViewController.modalPresentationStyle = .overFullScreen 

    let window = UIApplication.shared.keyWindow! 
    if let modalVC = window.rootViewController?.presentedViewController { 
     // HERE it does crash 
     modalVC.present(lockScreenViewController, animated: false, 
         completion: nil) 
    } else { 
     window.rootViewController!.present(lockScreenViewController, animated: false, completion: nil) 
    } 
}

I 선을 표시 :

class LockScreenViewController: UIViewController { 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     let blurEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .light)) 
     blurEffectView.frame = self.view.bounds 
     blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight] 

     view.addSubview(blurEffectView) 
     view.sendSubview(toBack: blurEffectView) 
    } 
}

backgroundForegroundDelegate 인 TabBarController를 상기 해당 잠금 화면을 제시하는 다음을 수행 할 것이다 충돌이 발생한 곳.

동일한 휴대 전화에서 동일한 OS로 재생산하지 못했습니다.

무엇이 잘못 될 수 있으며 어떻게 안전하게 만들 수 있습니까?
