如何在UIView上关闭SFSafariViewController

Question

class CustomScreen: UIView, SFSafariViewControllerDelegate {
@IBAction func webPageBtnAction(_ sender: Any) {
    if #available(iOS 9.0, *) {
        let svc = SFSafariViewController(url: NSURL(string: "https://stackoverflow.com/")! as URL)
        svc.delegate = self
        let appDelegate = UIApplication.shared.delegate as! AppDelegate
        appDelegate.window?.rootViewController = svc
    } else {
        // Fallback on earlier versions
    }
}

@available(iOS 9.0, *)
func safariViewControllerDidFinish(_ controller: SFSafariViewController) {
    controller.dismiss(animated: false, completion: nil)
}
}

出于某种原因，我不能驳回SFSafariViewController。有什么想法吗？

由于您在代码中替换了rootViewController (对于这种情况来说，这是一种不好的做法)，因此您应该简单地呈现SFSafariViewController：

let svc = SFSafariViewController(url: NSURL(string: "https://stackoverflow.com/")! as URL)
svc.delegate = self
UIApplication.shared.keyWindow?.rootViewController?.present(svc, animated: true, completion: nil)

据我所知，这是一种糟糕的做法，因为safariViewControllerDidFinish永远不会被调用，因为CustomScreen将从当前rootViewController的替换中释放
