你好，麻烦提供出现问题的具体机型、微信版本号、系统版本号，以及能复现问题的代码片段（https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html）

您好,iPhone X ,ios 13.6.1, 微信版本号:7.0.18,

[WXApi startLogByLevel:WXLogLevelDetail logBlock:^(NSString * _Nonnull log) {

        DLog(@"微信API Log: %@\n",log);

    }];

    BOOL isSuccess = [WXApi registerApp:@"wx1cd4b5c6e3fcfd7e" universalLink:@"https://apiexpress.365tx.com/.well-known/"];

    if (isSuccess) {

        DLog(@"微信API: 注册成功\n");

    } else {

        DLog(@"微信API: 注册失败\n");

    }

    //调用自检函数

    [WXApi checkUniversalLinkReady:^(WXULCheckStep step, WXCheckULStepResult* result) {

        DLog(@"微信API自检函数: %@, %u, %@, %@", @(step), result.success, result.errorInfo, result.suggestion);

    }];
