微信支付IOS集成流程

1，官方帮助文档：https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=11_1

2，下载SDK

3，修改IOS配置：在Build Phases选项卡的Link Binary With Libraries中，增加以下依赖

libz.tbd
        libsqlite3.0.tbd
        SystemConfiguration.framework
        CoreTelephony.framework
        QuartzCore.framework
        libWeChatSDK.a

 4，注册APP：修改AppDelegate文件

class AppDelegate: UIResponder, UIApplicationDelegate, WXApiDelegate {

    ......

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        self.initWeixinPay()
        return true
    }

    func onResp(_ resp: BaseResp!) {
        var strMsg = "\(resp.errCode)"
        Logger.debug(strMsg)
        if resp.isKind(of: PayResp.self) {
            switch resp.errCode {
            case 0 :
                NotificationCenter.default.post(name: PayHelper.Notification_WX_Result, object: nil)
            case -2:
                strMsg = "您已取消支付，请尽快完成支付"
            default:
                strMsg = "支付失败：\(resp.errStr)"
                Logger.debug("retcode = \(resp.errCode), retstr = \(resp.errStr)")
            }
        }
        if resp.errCode != 0{
            let alert = UIAlertView(title: nil, message: strMsg, delegate: nil, cancelButtonTitle: "好的")
            alert.show()
        }
    }
    
    func initWeixinPay(){
        WXApi.registerApp(GlobalConstant.WX_APP_ID, withDescription: "APP描述")
    }
