ios - 使用 Square SDK Swift 3 进行支付

Question

当我尝试使用来自 Github (https://github.com/square/SquareRegisterSDK-iOS) 的 Square SDK 进行付款时，我无法在 Square POS 应用程序中找到我从我的应用程序传递过来的金额。

请找出我实际遵循的以下步骤。

1. 我已经从下面的 git hub 链接下载了 Square Register SDK。

https://github.com/square/SquareRegisterSDK-iOS

1. 我使用 cocoa pods 运行了该应用程序，并且我已在我的项目中成功安装了 pod 文件。

2. 我在“我的应用程序”部分的客户端登录中创建了一个测试应用程序。

应用名称:MyApp

应用程序 ID:XXXXXXXXXXXXXX(我在 Square Dashboard 中的应用程序 ID)

1. 我已经在 Register Api 部分注册了我的 Bundle Id 和 Callback Url

iOS 应用包 ID:我的包 ID

iOS 应用程序 URL 方案:我的回调 Url

1. 因为我的帐户已激活，可以通过应用程序接收付款。

2. 现在回到我的代码，我只是采用了 Square Register SDK ----> SwiftCharge 类方法。

3. 请找到我用于收费的以下代码，请让我知道我要进行的任何更正。

   导入SquareRegisterSDK 导入 UIKit 让 yourClientID = "xxxxxxxxxx" let yourCallbackURL = URL(string: "MyApp://callback")!

   枚举部分:Int { case amount = 0, supportedTenderTypes, optionalFields, 设置

   init?(at indexPath: IndexPath) {
       self.init(rawValue: indexPath.section)
   }
   

   让 allTenderTypes: [SCCAPIRequestTenderTypes] = [.card, .cash, .other, .squareGiftCard, .cardOnFile]

   扩展字符串{ 变量 nilIfEmpty:字符串？ { 返回是空的？无: self }

   类 View Controller :UIViewController {

   var supportedTenderTypes: SCCAPIRequestTenderTypes = .card
   var clearsDefaultFees = false
   var returnAutomaticallyAfterPayment = true
   
   @IBOutlet weak var currencyField: UITextField!
   @IBOutlet weak var amountField: UITextField!
   
   @IBOutlet weak var notesField: UITextField!
   @IBOutlet weak var userInfoStringField: UITextField!
   @IBOutlet weak var merchantIDField: UITextField!
   @IBOutlet weak var customerIDField: UITextField!
   
   
   override func viewDidLoad() {
       super.viewDidLoad()
       // Do any additional setup after loading the view, typically from a nib.
   }
   
   override func didReceiveMemoryWarning() {
       super.didReceiveMemoryWarning()
       // Dispose of any resources that can be recreated.
   }
   
   override func awakeFromNib() {
       super.awakeFromNib()
   
       // Always set the client ID before creating your first API request.
       SCCAPIRequest.setClientID(yourClientID)
   }
   
   
   @IBAction func charge(sender: AnyObject) {
   
       let currencyCodeString = "USD"
       let amountString = "500"
   
       let amount: SCCMoney
       guard let amountCents = Int(amountString) else {
           showErrorMessage(title: "Invalid Amount", message: "\(amountString) is not a valid amount.")
           return
       }
   
       do {
           amount = try SCCMoney(amountCents: amountCents, currencyCode: currencyCodeString)
       } catch let error as NSError {
           showErrorMessage(title: "Invalid Amount", error: error)
           return
       }
   
       let userInfoString = "Radhachandan"
       let merchantID = ""
       let customerID = ""
       let notes = "Sample Test"
   
       let request: SCCAPIRequest
       do {
           request = try SCCAPIRequest(callbackURL: yourCallbackURL,
                                       amount: amount,
                                       userInfoString: userInfoString,
                                       merchantID: merchantID,
                                       notes: notes,
                                       customerID: customerID,
                                       supportedTenderTypes: supportedTenderTypes,
                                       clearsDefaultFees: clearsDefaultFees,
                                       returnAutomaticallyAfterPayment: returnAutomaticallyAfterPayment)
       } catch let error as NSError {
           showErrorMessage(title: "Invalid Amount", error: error)
           return
       }
   
       do {
           try SCCAPIConnection.perform(request)
   
       } catch let error as NSError {
   
   
   showErrorMessage(title: "Cannot Perform Request", error: error)
           return
       }
      }
   
   
   private func showErrorMessage(title: String, error: NSError) {
       showErrorMessage(title: title, message: error.localizedDescription)
   }
   
   private func showErrorMessage(title: String, message: String) {
       let alertView = UIAlertController(title: title, message: message, preferredStyle: .alert)
       alertView.addAction(UIAlertAction(title: "Dismiss", style: .default, handler: nil))
       present(alertView, animated: true, completion: nil)
   }
   

4. 截至目前，它已重定向至 Square Point Of Sale 应用程序，但未显示我已通过的金额。

非常感谢您的友好反馈。

Answer 1

尝试像这样修改您的代码:

...
let userInfoString = "Radhachandan"
    let merchantID = nil
    let customerID = nil
    let notes = "Sample Test"
...

您已提醒我们在为这些参数传递空字符串时存在错误，我们将尽快进行修复。
