微信支付那點事

1.首先下載SDK；導入工程；

2.在xcode中打開項目設置URL Schemes：（爲本身）APPId；

3.導入頭文件，在AppDelegate中調用[WXApi registerApp：@"APPId" withDescription：@"weiXinPayDemo"];註冊APPID；

4.調起支付：

  ///1.調用微信支付

        let req = PayReq()

        req.partnerId = model?.partnerid

        req.prepayId = model?.prepayid

        req.nonceStr = model?.noncestr

        req.timeStamp = UInt32((model?.timestamp!)!)

        req.package = model?.package

        req.sign = model?.sign

        WXApi.send(req)

5.支付結果回調

func onResp(_ resp: BaseResp!){

        var strTitle = "支付結果"

        var strMsg = "what:\(resp.errCode)"

        if "\(resp.classForCoder)" == "PayResp"{

            print("retcode = \(resp.errCode), retstr = \(resp.errStr)")

            switch resp.errCode

            {

  case 0 :NotificationCenter.default.post(name: NSNotification.Name(rawValue: "WXPaySuccessNotification"), object: nil)

              default:

                strMsg = "支付失敗，請您從新支付!"

            }

        }

    }
