如何將導航欄和標簽欄設置為通過UIPopoverViewController的視圖？

Question

我自定義了一個UIViewController作為PopoverViewController，當我展示它時，我既不能觸摸導航欄，也不能觸摸選項卡欄

我搜索了一段時間，然后得到了：在第一個ViewController代碼的prepare（對於segue：UIStoryboardSegue，發件人：Any？）中：

if segue.identifier == "ShowChoice"{
      let poper = segue.destination
      poper.modalPresentationStyle = .popover
      poper.popoverPresentationController?.delegate = self
      let point = CGPoint(x: self.view.bounds.midX, y: self.view.bounds.midY + 5)
      poper.popoverPresentationController?.sourceView = self.view
      poper.popoverPresentationController?.sourceRect = CGRect(origin: point, size: CGSize.zero)
      poper.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)

//here I set [self.view] to passthroughViews and it work i can interact with all thing in self.view but I can't interact with Navigation Button or Tab bar item!

            poper.popoverPresentationController?.passthroughViews = [self.view]
        }
    }

我只能將UIView設置為passthroughViews，但我想設置導航欄或標簽欄

謝謝！

Answer 1

我終於找到了自己，只需將[self.tabBarController？.tabBar，self.navigationController？.navigationBar]強制轉換為[UIView]

poper.popoverPresentationController?.passthroughViews = [self.tabBarController?.tabBar,self.navigationController?.navigationBar] as! [UIView]

Answer 2

有趣的是， popoverPresentationController.passthroughViews內部的項目順序popoverPresentationController.passthroughViews重要！

例如，如果您想添加所有視圖和導航欄，則必須將導航欄放置在列表的開頭，否則觸摸只會饋送到其下方的任何項目

這是我的代碼：

 popoverPresentationController.passthroughViews = [self.view]
 if let navBar = self.navigationController?.navigationBar {
     popoverPresentationController.passthroughViews?.insert(navBar, at: 0)
 }

另外，請記住關閉popoverView，如果這樣做是為了能夠使用后退按鈕
