设置DarkTheme无效Braintree iOS v4 SDK

Question

文档清楚地表明可以做到，轻而易举： https://developers.braintreepayments.com/guides/drop-in/customization/ios/v4#themes

我确实可以将primaryTextColor自定义为红色。

这是一个屏幕截图，该屏幕演示了红色有效但不是darkTheme：

这是我的UIViewController中的代码：

因此布伦特里（Braintree）的documentation on Theme's在IMO措辞上选择不当。

该说明对我有误解：“要改用Dark主题，请在初始化Drop-in之前调用此方法”。但是，您必须在设置darkTheme之前初始化或实例化插件。

该说明最好读为：“要改用Dark主题，请在展示Drop-in之前调用此方法”

这是我的工作代码：

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    showDropIn(clientTokenOrTokenizationKey: clientToken)
}

func showDropIn(clientTokenOrTokenizationKey: String) {
    let request =  BTDropInRequest()
    request.vaultManager = true

    dropIn = BTDropInController(authorization: clientTokenOrTokenizationKey, request: request)
    { (controller, result, error) in
        if (error != nil) {
            print("ERROR")
        } else if (result?.isCancelled == true) {
            print("CANCELLED")
        } else if let result = result {
            // Use the BTDropInResult properties to update your UI
            // result.paymentOptionType
            // result.paymentMethod
            // result.paymentIcon
            // result.paymentDescription
        }
        controller.dismiss(animated: true, completion: nil)
    }

    BTUIKAppearance.darkTheme()
    BTUIKAppearance.sharedInstance()?.primaryTextColor = UIColor.lightGray
    self.present(dropIn!, animated: true, completion: nil)
}
