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];

我也是在第6步报错，不过有的手机可以。找到的原因是安装app的时候苹果没有请求对应的通用链接域名，不知道怎么解决。麻烦技术看到麻烦解决下。
自检到第六步就失败 请问下问题出在哪里？已经摸索很久麻烦看下 打印日志如下： 5, 0, Universal Link check failed. The application is launched by WeChat via scheme, Common problems self-check guide: [微信开放平台App iOS端接入新版本SDK 常见问题自查指引]https://developers.weixin.qq.com/community/develop/doc/000ce0403bc9d0ea1a0a67f415b409

官网文档我仔细对过，没发现问题 ，但就是第六步验证过不了，在safair自检跳转也是没问题。 请问怎么解决呢
另外应用通过微信审核后，修改微信后台的开发信息栏，要不要审核时间呢？
友盟报错日志“微信分享报错'由于invalid_app无法分享到微信。”，友盟反馈到的信息是因为微信内部错误，想请问一下是什么原因呢？
你好，自检全部通过。 回调走的 continueUserActivity 方法，然后就不跳转到微信了。
点击分享，跳转到微信，再跳回到 app，就停止了，为什么？
wx自检:6, 1, All Check Passed!,
WeChatSDK: wxlog:WXCheckULStepResult[success: 1, errorInfo: All Check Passed!, suggestion: ]
系统是 iOS 13
你好 我这边其他页面都微信分享正常 只有一个集成了网易直播的页面 能跳转到微信但是不会显示联系人列表 分享到朋友圈也是不能显示朋友圈分享的界面
[WXApi sendReq:req completion:^(BOOL success) {
}];
但是在这个方法的回调里打了断点后再运行就能正常跳转 自检方法也只能到第四步 求解决

第4步一直过不去，不知道为什么
