4. appdelegate里加

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        if url.host == "safepay"{
            AlipaySDK.defaultService().processOrder(withPaymentResult: url){
                value in
                let code = value!
                let resultStatus = code["resultStatus"] as!String
                var content = ""
                print(resultStatus)
                switch resultStatus {
                case "9000":
                    content = "支付成功"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPaySucceess), object: content)
                case "8000":
                    content = "订单正在处理中"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayUnknowStatus), object: content)
                case "4000":
                    content = "支付失败"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayDefeat), object: content)
                case "5000":
                    content = "重复请求"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayDefeat), object: content)
                case "6001":
                    content = "中途取消"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayDefeat), object: content)
                case "6002":
                    content = "网络连接出错"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayDefault), object: content)
                case "6004":
                    content = "支付结果未知"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayUnknowStatus), object: content)
                default:
                    content = "支付失败"
                    NotificationCenter.default.post(name: NSNotification.Name(rawValue: aliPayDefeat), object: content)
                    break
                }
            }
        }
        return true
    }

5. 调用 orderStr为后台返回的字符串
   AlipaySDK.defaultService()?.payOrder(orderStr, fromScheme: ZhifuBaoScheme, callback: { (result) in print(result) })
