5.AppDelegate

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // WXAppID为微信申请的App ID，WXUniversalLinks为微信申请的Universal Links
        WXApi.registerApp(WXAppID, universalLink: WXUniversalLinks)
        return true
    }

重写 AppDelegate 的 handleOpenURL 和 openURL 方法

// iOS9.0及以后推荐使用
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
      let handleUrlStr = url.absoluteString
      if let handleUrl = URL(string: handleUrlStr) {
          return WXApi.handleOpen(handleUrl, delegate: self)
      }
      return false
    }

// 必须实现
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
      let handleUrlStr = url.absoluteString
     if let handleUrl = URL(string: handleUrlStr) {
         return WXApi.handleOpen(handleUrl, delegate: self)
     }
    return false
    }

重写AppDelegate的continueUserActivity方法

func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
        return WXApi.handleOpenUniversalLink(userActivity, delegate: self)
    }

分享结果或支付结果回调App

// 实现WXApiDelegate代理方法
func onResp(_ resp: BaseResp) {
    guard resp.isKind(of: PayResp.self) else {
         // 微信分享结果回调
         let wxSendResult = resp as! SendMessageToWXResp
         debugPrint(wxSendResult.errCode)
         return
     }
    // 微信支付结果回调
    let payresp = resp as! PayResp
    debugPrint(payresp.errCode)

唤起微信支付：

// 数据model用于接收后端返回的唤起微信支付必要参数
let req = PayReq()
/** 商家向财付通申请的商家id */
req.partnerId = model.partnerid
/** 预支付订单 */
req.prepayId = model.prepayid
/** 随机串，防重发 */
req.nonceStr = model.noncestr
/** 时间戳，防重发 */
req.timeStamp = UInt32(model.timestamp)
/** 商家根据财付通文档填写的数据和签名 */
req.package = model.package
/** 商家根据微信开放平台文档对数据做的签名 */
req.sign = model.sign
WXApi.send(req) { (bool) in
    // 返回是否成功唤起微信支付
    debugPrint(bool)
 }
