点击视图控制器后INUIHostedViewControlling，有没有办法向应用程序发送一些参数/URL？

例如在 Widget 扩展中有： 

self.extensionContext?.open(cardURL, completionHandler: nil)

似乎某些扩展类型在使用 extensionContext 时受到更多限制。我在键盘扩展上遇到了同样的问题。这可能有点hacky，但下面的代码对我有用。

func openUrl(url: URL?) {
    let selector = sel_registerName("openURL:")
    var responder = self as UIResponder?
    while let r = responder, !r.responds(to: selector) {
        responder = r.next
    }
    _ = responder?.perform(selector, with: url)
}

func canOpenUrl(url: URL?) -> Bool {
    let selector = sel_registerName("canOpenURL:")
    var responder = self as UIResponder?
    while let r = responder, !r.responds(to: selector) {
        responder = r.next
    }
    return (responder!.perform(selector, with: url) != nil)
}

正如https://stackoverflow.com/a/44694703/2064473提出的
