I'm working on an iPad app and I need to be able to download and unzip a collection of images to display. Is this possible to do natively in iOS 7? iOS 6?
Using SSZipArchive, the line below would unzip a zip file:
[SSZipArchive unzipFileAtPath:path toDestination:destination];
It turns out that in iOS 7, Apple added support to natively unzip files in iMessage and in the Mail app! Not sure if this is 100% related, but it might help. See this link for more info.
