Q：Universal Link校验不通过，无法调起微信支付？
A：请开发者在调用register接口前，打开WXApi.h的日志接口，观察报错日志和原因：
+ (voidstartLogByLevel:(WXLogLevel)levellogBlock:(WXLogBolock)logBlock
Q：接入新SDK，跳到微信后再回跳App，流程就中止？
A：1. 首先，微信唤起App，App一定会收到系统回调。请确认系统回调是Scheme回调还是Universal Links回调。
2. 如果是Scheme回调，请检查是否走了UISceneDelegate(XCode11构建的项目)，或是UIApplicationDelegate。它们的回调方法分别是
- (void)scene:(UIScene *)scene openURLContexts:(NSSetUIOpenURLContext *> *)URLContexts;
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionaryUIApplicationOpenURLOptionsKey, id> *)options;
3. 如果是Universal Links回调，同样也检查是否走了UISceneDelegate(XCode11构建的项目)，或是UIApplicationDelegate。它们的回调方法分别是
- (void)scene:(UIScene *)scene continueUserActivity:(NSUserActivity *)userActivity
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void(^)(NSArrayidUIUserActivityRest
oring>> * __nullable restorableObjects))restorationHandler
4. 因为考虑兼容旧版本微信，因此无论Scheme或Universal Links回调都必须处理。 在重写回调方法后，需要分别调用WXApi的handleOpenUrl和handleOpenUniversalLink方法
示例：
- (voidscene:(UIScene *)scene continueUserActivity:(NSUserActivity *)userActivity {
return [WXApi handleOpenUniversalLink:userActivity delegate:self
- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:void(^)(NSArrayidUIUserActivityRest
oring>> * __nullable restorableObjects))restorationHandler {
return [WXApi handleOpenUniversalLink:userActivity delegate:self];

哪位大神帮忙看看，universal link跳转都没问题，但是分享报错
wxlog:Error:fail to load Keychain status:-25300, keyData null:1
用检测方法一直不能到最后一步
step = WXULCheckStep(0), success = true, error = check passed, suggestion =
step = WXULCheckStep(1), success = true, error = check passed, suggestion =
step = WXULCheckStep(2), success = true, error = check passed, suggestion =
step = WXULCheckStep(3), success = true, error = check passed, suggestion =
wxlog:launch app with ul only success
step = WXULCheckStep(4), success = true, error = check passed, suggestion =
wxlog:Successfully starting WeChat with the universal link.
跳转到小程序，每次都跳转两次。App---微信链接--App--小程序
Universal Link 配置对的
App更新微信1.8.6.1版本SDK后出现“正在连接”的提示？每次分享出现二跳

你好，我的项目比较老，并没有UISceneDelegate，目前在iOS13上测试Universal link有效，但是不走onResp函数，请问如何处理呢？是必须让我的项目适配UISceneDelegate才能升级到最新的SDK吗？感谢。
不是Xcode11创建的项目，就不需要处理UISceneDelegate了吧
