如何在UIView上关闭SFSafariViewController

Posted 2021-04-18

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)
}
}

在某些原因，我无法解雇SFSafariViewController。任何的想法？

答案

因为在你的代码中你正在替换rootViewController（对于这种情况来说是一种不好的做法），你应该简单地介绍SFSafariViewController这样做：

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，这是一个不好的做法，因为safariViewControllerDidFinish永远不会被调用，因为CustomScreen将被取代分配当前的rootViewController
