title: Read Byte Array From URL and Convert To PDF in iOS
body: <p>I have a service in Windows that returns a PDF data, which it's in the database in a varbinary field. This service returns the PDF data as a Byte Array in JSON format <br>
  How can I read this data and convert it to PDF again, in my app in Xcode?<br>
  Which is the correct structure data to retrieve this byte array? NSArray? NSMutableArray?<br>
  I want to store this data, and I'm using a NSData structure...<br>
  Thanks</p>
