Question

我正在尝试在我的应用程序中显示模式弹出窗口。我确实看到它显示但框架不正确且方向箭头不可见

以下是我用来点击栏按钮时显示弹出窗口的代码

    @IBAction func filterBarButtonAction(_ sender: AnyObject) {


    let vc = UIStoryboard(name: "MapViewController", bundle: Bundle(for: type(of: self))).instantiateViewController(withIdentifier: "FilterModal")
    vc.modalPresentationStyle = .overCurrentContext
    vc.popoverPresentationController?.sourceRect = sender.bounds
    vc.popoverPresentationController?.sourceView = sender as? UIView
    vc.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.up;
    vc.popoverPresentationController?.delegate = self
    self.searchResultsController.present(vc, animated: true, completion: nil)

}

[当前视图显示如下] [1]

点击UIBarButton时，我需要做些什么更改才能显示带有箭头指示的弹出窗口

修改：根据Pierce的建议，当我改为

vc.modalPresentationStyle = .popover

I see this

I want to display some like this

Answer 1

在我添加

后，它正在工作

    public func adaptivePresentationStyle(for controller:UIPresentationController) -> UIModalPresentationStyle {
    print("adaptive was called")
    return .none
}

感谢Pierce，将modalPresentationStyle设置为popup是正确的方法

无法显示模态弹出控制器
