# SSZipArchive
ZipArchive is a simple utility class for zipping and unzipping files on iOS, macOS and tvOS.
- Unzip zip files;
- Unzip password protected zip files;
- Unzip AES encrypted zip files;
- Create zip files;
- Create large (> 4.3Gb) files;
- Create password protected zip files;
- Create AES encrypted zip files;
- Choose compression level;
- Zip-up NSData instances. (with a filename)
## Installation and Setup
*The main release branch is configured to support Objective-C and Swift 3+.*
SSZipArchive works on Xcode 7 and above, iOS 9 and above, tvOS 9 and above, macOS 10.9 and above, watchOS 2 and above.
### CocoaPods
In your Podfile:
`pod 'SSZipArchive'`
You should define your minimum deployment target explicitly, like:
`platform :ios, '9.0'`
Recommended CocoaPods version should be at least CocoaPods 1.7.5.
### SPM
Add a Swift Package reference to https://github.com/ZipArchive/ZipArchive.git (SSZipArchive 2.4.2 and higher or master)
### Carthage
In your Cartfile:
`github "ZipArchive/ZipArchive"`
Note: We are no longer releasing a Carthage pre-built package as of 2.2.3. Developers are encouraged to build one themselves.
### Manual
1. Add the `SSZipArchive` and `minizip` folders to your project.
2. Add the `libz` and `libiconv` libraries to your target.
3. Add the `Security` framework to your target.
4. Add the following GCC_PREPROCESSOR_DEFINITIONS: `HAVE_INTTYPES_H HAVE_PKCRYPT HAVE_STDINT_H HAVE_WZAES HAVE_ZLIB $(inherited)`.
SSZipArchive requires ARC.
## Usage
### Objective-C
```objective-c
//Import "#import <ZipArchive.h>" for SPM/Carthage, and "#import <SSZipArchive.h>" for CocoaPods.
// Create
[SSZipArchive createZipFileAtPath:zipPath withContentsOfDirectory:sampleDataPath];
// Unzip
[SSZipArchive unzipFileAtPath:zipPath toDestination:unzipPath];
```
### Swift
```swift
//Import "import ZipArchive" for SPM/Carthage, and "import SSZipArchive" for CocoaPods.
// Create
SSZipArchive.createZipFileAtPath(zipPath, withContentsOfDirectory: sampleDataPath)
// Unzip
SSZipArchive.unzipFileAtPath(zipPath, toDestination: unzipPath)
```
