Apple rejected App saying that 2.5 - Apps that use non-public APIs will be rejected

Hi All,

I got a very strange rejection message from apple yesterday. They says I am suing non-public API where as I am not using any, below is the message they said. Please help me resolve this

2.5 - Apps that use non-public APIs will be rejected
Hello Vijay,

Thank you for your question. Specifically, we found that your app includes a category, “HackishAccessoryHiding”, for UIWebView that includes methods meant to programmatically access a displayed UIWebBrowserView object. If this is part of the Ionic framework, it would be appropriate to reach out to them if you cannot remove the at-issue code on your own.

Regards,
Vijay
