1溪北、蘋果后臺appid開啟Associated Domains，重新生成描述文件，證書不用重新生成
2摹恰、工程Capabilities -> Associated Domains添加域名applinks:www.xx.com applinks后面的域名不加https
3沪么、微信后臺universal link傳入https://域名/ 注意https開頭/結尾
4硼婿、LSApplicationQueriesSchemes添加wechat、weixin和weixinULAPI
5禽车、域名根目錄下配置文件apple-app-site-association寇漫，內容如下

{
    "applinks": {
        "apps": [],
        "details": [
        {
            "appID": "teamid.bundleid",
            "paths": [ "*"]
        },
        {
            "appID": "teamid.bundleid",
            "paths": [ "*"]
        }
        ]
    }
}

6、appdelegate里設置系統(tǒng)回調殉摔，必須設置州胳，負責會出現(xiàn)微信和app來回跳的問題
//設置Universal Links系統(tǒng)回調

- (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler{
    
    if (![[UMSocialManager defaultManager] handleUniversalLink:userActivity options:nil]) {
        NSLog(@"其他SDK的回調");
    }
    return YES;
}

7、配置友盟universal link參數(shù)

[UMSocialGlobal shareInstance].universalLinkDic = @{@(UMSocialPlatformType_WechatSession):kWXUniversalLinks};

8逸月、微信通用鏈接檢查栓撞，調試使用，調試完屏蔽,總共7步彻采，都通過則沒有問題腐缤，如果第6步有問題會卡在第4或5步

 [WXApi startLogByLevel:WXLogLevelDetail logBlock:^(NSString * _Nonnull log) {
        NSLog(@"微信日志%@",log);
    }];
    NSLog(@"微信版本:%@",[WXApi getApiVersion]);
    [WXApi registerApp:kWXAppKey universalLink:kWXUniversalLinks];
    [WXApi checkUniversalLinkReady:^(WXULCheckStep step, WXCheckULStepResult * _Nonnull result) {
        NSLog(@"微信日志檢查 %@, %u, %@, %@", @(step), result.success, result.errorInfo, result.suggestion);
    }];
