Question

我已经将UIViewController定制为PopoverViewController，当我呈现它时，我无法触摸导航栏上的Tab栏

我一直在搜索，我得到了：第一个ViewController代码的准备（对于segue：UIStoryboardSegue，sender：Any？）：

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]
        }
    }

我只能将UIView设置为passthroughViews，但我想设置导航栏或标签栏

谢谢你！

Answer 1

我终于通过简单地将[self.tabBarController？.tabBar，self.navigationController？.navigationBar]转换为[UIView]

来自行找到

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

Answer 2

有趣的是，popoverPresentationController.passthroughViews中项目的顺序很重要！

例如，如果您想添加所有视图和导航栏，则必须将导航栏置于列表的开头，否则触摸只会被馈送到其下的任何项目

这是我的代码：

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

此外，请记住关闭popoverView，因为这样做是为了能够使用后退按钮

如何设置导航栏和标签栏作为UIPopoverViewController的视图？
