您可以使用以下方法在 drop in 方法中获取付款随机数 让nonce = result. paymentMethod!.nonce

示例:-

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

            let nonce = result.paymentMethod!.nonce

            print( nonce)

        }
        controller.dismiss(animated: true, completion: nil)
    }
    self.present(dropIn!, animated: true, completion: nil)
}
