Need assistance with converting scanned PDF to searchable text

[tmmp7836]

I have scanned a portion of a book into a PDF document and I would like to use an iOS app to read and annotate this document. In order to highlight text in the document, I need to convert the PDF into searchable text. I assume that OCR in Adobe Acrobat DC should be capable of making this conversion, however I'm uncertain how to do this. Can someone provide some assistance? Thank you very much.

I found the solution online and I'll post it here, in the event that others have the same question.

Acrobat can now run OCR on a scanned PDF that contains images with live text on them. Earlier, if you would run OCR on such a PDF, you would see the error message – “This page contains renderable text.”  

Run OCR on scanned documents with live text:

1. Open the scanned PDF in Acrobat DC

2. Go to Tools > Enhance Scan > Recognizable Text > In This File.

3. Click Settings in the toolbar. The Recognize Text dialog box is displayed.

4. In the Output drop-down menu, choose Searchable Image or Searchable Image (exact) and click OK.

5. Click Recognize Text in the toolbar.
