swift - 假设你的意思是'可选。没有任何'; 你的意思是“LABiometryType.none”吗？

Question

要么是这样：

或警告，当 .none 被删除时，并非所有情况都得到处理。我怎么能治好这个？

        switch(globalLAcontext?.biometryType) {
            case .touchID:
                titleLabel.text = Localization.string("v1_dotouch_title", "")
                descriptionLabel.text = Localization.string("v1_dotouch_desc","")
                let i = UIImage.image(name: "fingerprint")
                authButton.setImage(i, for: .normal)
                nativeAuthenticationButton.setTitle(Localization.string("v1_dotouch_title", ""), for: .normal)
                showNativeAuthDupButton = true

            case .faceID:
                titleLabel.text = Localization.string("v1_doface_title", "")
                descriptionLabel.text = Localization.string("v1_doface_desc","")
                nativeAuthenticationButton.setTitle(Localization.string("v1_doface_title", ""), for: .normal)
                showNativeAuthDupButton = true

            case .some(.none): fallthrough
            default:
                titleLabel.text = nil
            }
