【问题描述】：

如何以模态显示 viewController。我是 ios 的新手，正在使用 swift4 我试试这个

 let userVC = mainStoryboard.instantiateViewController(withIdentifier: 
  "menuC") as! MenuController
    userVC.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
      userVC.navigationController?.modalPresentationStyle = 
    UIModalPresentationStyle.overCurrentContext
    present(userVC, animated: true, completion: nil)

【参考方案1】：

这样做

if let presentedViewController = self.storyboard?.instantiateViewController(withIdentifier: "menuC") 
        presentedViewController.providesPresentationContextTransitionStyle = true
        presentedViewController.definesPresentationContext = true
        presentedViewController.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext;
        presentedViewController.view.backgroundColor = UIColor.init(white: 0.4, alpha: 0.8)
        self.present(presentedViewController, animated: true, completion: nil)
