从嵌入在 UITabBarController 中的 UIViewController 我执行模态 segue

self.present(.....

在我的 UITabBarController 中成为“自我”我的视图控制器。新的 ViewController 完美展现，姑且称之为模态ViewController2呈现ViewController1。如果我尝试关闭ViewController2它，它总是会因未知异常而崩溃。libc++abi.dylib: terminating with uncaught exception of type NSException. ViewController2嵌入在 aUINavigationController但这ViewController2是唯一一个崩溃的。

我试过解雇presentingViewController, presentationController，presentedViewController但self.navigationController?.dismiss没有什么对我有用。

架构是：UITabBarController->ViewController1 -modally present- UINavigationController->ViewController2

这是我的演示代码：

guard let vcDetail = UIStoryboard(name: "ProjectDetailStoryBoard\(currentDevice)", bundle: nil).instantiateViewController(withIdentifier: "vcDetailProject") as? ProjectDetailController else{return}
    vcDetail.instantiatedFromPushNotification = true
    vcDetail.projectId = key

    let vc = UINavigationController(rootViewController: vcDetail)

    UIApplication.topViewController()?.present(vc, animated: true, completion: nil)

这是我的解雇代码：

@IBAction func dismissView(){

    dismiss(animated: true, completion: nil)
}
