I can't get only ios in analytics

On the android side, custom events can be acquired, but it seems that only the ios side is always 0 and cannot be acquired.
Does iOS need special settings?

 

Can you post a screenshot? There are no special settings. Ensure you check the return code, and please don't post unnecessary polls

AnalyticsResult ar = Analytics.CustomEvent("HelloWorld");
Debug.Log("Result = " + ar.ToString());
