我为UIButton实现了popover:
@objc func showList(sender: AnyObject?) {
guard let buttonView = sender?.value(forKey: "view") as? UIButton else { return }
guard let popVC = R.storyboard.first.VC() else { return }
popVC.modalPresentationStyle = .popover
let popOverVC = popVC.popoverPresentationController
popOverVC?.delegate = self
popOverVC?.sourceView = buttonView
popOverVC?.sourceRect = CGRect(x: 0, y: 190, width: 0, height: 0)
popOverVC?.permittedArrowDirections = .init(rawValue: 0)
popVC.preferredContentSize = CGSize(width: 150, height: 250)
showedViewController.present(popVC, animated: true, completion: nil)
}
extension VCInteractor: UIPopoverPresentationControllerDelegate {
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return .none
}
}
它运行良好,但我需要一个修复 - 我想为我的popover隐藏UIVisualEffectBackdropView
(就像我的UITableViewController下的模糊一样)。所以,我找不到任何关于如何禁用(隐藏)这种模糊的信息,你有什么想法吗?

我已使用自定义类修复了我的问题
class PopoverBackgroundView: UIPopoverBackgroundView {
override init(frame: CGRect) {
super.init(frame: frame)
self.layer.shadowColor = UIColor.clear.cgColor
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override static func contentViewInsets() -> UIEdgeInsets {
return UIEdgeInsets.zero
}
override static func arrowHeight() -> CGFloat {
return 0
}
override var arrowDirection: UIPopoverArrowDirection {
get { return UIPopoverArrowDirection.down }
set {
setNeedsLayout()
}
}
override var arrowOffset: CGFloat {
get { return 0 }
set {
setNeedsLayout()
}
}
}
我已经添加了它
popOverVC?.popoverBackgroundViewClass = PopoverBackgroundView.self
这就是全部

在这里,我有一个非常简单的解决方案。
let appearance = UIVisualEffectView.appearance(whenContainedInInstancesOf: [NSClassFromString("_UIPopoverStandardChromeView")! as! UIAppearanceContainer.Type])
appearance.effect = UIVisualEffect()
将代码添加到AppDelegate.swift文件或应用初始化的任何位置。
