title: How to check if a zip file is password protected in IOS?
body: <p>I am using <a href="https://code.google.com/p/ziparchive/" rel="nofollow">ZipArchive</a> to extract zip files in an iOS application, but I want to know before openning the file if it's password protected or not so that I can pass the password to the UnZipOpenFile function.</p>
