SimpleUnzipper

Unzip single, unencrypted (no password), non-zip64 (large than 4GB) files, written in Swift 1.2. It's driven by a private (currently) EPUB parser project, since EPUB is simply a zip file.

Installation

SimpleUnzipper is encapsulated as a Framework. Drag SimpleUnzipper.xcodeproj into your project, add libz.dylib and SimpleUnzipper to “Linked Frameworks and Libraries” under “General” tab of target settings.

The most important step, don't forget to add correct path which contains SimpleUnzipper to target's Build Settings -> Swift Compiler - Search Paths -> Import Paths. As below shows, SimpleUnzipper is on the same directory as the target project.

If you add SimpleUnzipper inside your project dirctory, the Import Paths should be $(SRCROOT)/SimpleUnzipper

Example

SimpleUnzipper is very simple as its name, contains only a few public properties and methods.

import SimpleUnzipper
...
// create an unzipper with file URL or data
if let unzipper = SimpleUnzipper.createWithURL(url) {
  // or SimpleUnzipper.createWithData(data)
  
  // get all file names, including paths if available
  let files = unzipper.files
  
  // check if a file available
  let isAvailable = unzipper.containsFile("path/to/file.ext")
  
  // get data from a file
  let data = unzipper.dataForFile("path/to/file.ext")
  
}
