 # SSZipArchive

-SSZipArchive is a simple utility class for unzipping files based on [ZipArchive](http://code.google.com/p/ziparchive).
+SSZipArchive is a simple utility class for zipping and unzipping files. Features:

-Currently it only supports unzipping. In the future, creating zip files will be supported.
+* Unzipping zip files
+* Unzipping password protected zip files
+* Creating zip files
+* Appending to zip files
+* Zipping files
+* Zipping NSData with a filename
+* Works in ARC and non-ARC projects

 ## Adding to your project

 1. Add `SSZipArchive.h`, `SSZipArchive.m`, and `minizip` to your project.
 2. Add the `libz` library to your target

+You don't need to do anything regarding ARC. SSZipArchive will detect if you're not using ARC and add the required memory management code.
+
 ## Usage

-```objective-c
-NSString *path = @"path_to_your_zip_file";
-NSString *destination = @"path_to_the_folder_where_you_want_it_unzipped";
-[SSZipArchive unzipFileAtPath:path toDestination:destination];
+``` objective-c
+// Unzipping
+NSString *zipPath = @"path_to_your_zip_file";
+NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
+[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
+
+// Zipping
+NSString *zippedPath = @"path_where_you_want_the_file_created";
+NSArray *inputPaths = [NSArray arrayWithObjects:
+                       [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
+                       [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
+                       nil];
+[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];
 ```

+         Copyright (C) 1998-2010 Gilles Vollant (minizip) ( http://www.winimage.com/zLibDll/minizip.html )
+
+         Modifications for Zip64 support
+         Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com )
+
+         For more info read MiniZip_info.txt
+
+         Changes
+
+    Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
+    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
+               More if/def section may be needed to support other platforms
+    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
+                          (but you should use iowin32.c for windows instead)

Julius Parishy	f900d38036	Symbolic Link support. Adds support for ZIP files that include files that are symbolic links. See the note in SSZipArchive.m for more information about that. Includes a test that will probably only pass if you have GitHub for Mac installed because that's the program I used as a test to symlink against. I created the symbolic link with 'ln -s /Applications/GitHub.app SymbolicLink/GitHub.app' so I'm not entirely sure how it'll behave for hard links, but I can't test that right now.	2012-05-09 11:12:04 -04:00

Julius Parishy	b6f7f605fe	Fix for Issue #16 Fixes issues with files being truncated when their headers have values that represent smaller uncompressed sizes then the actual data. This generally fixes issues where the whatever program zipped the file fucked up the headers. The fix makes ssziparchive behave like other unzip utilities that ignore the header and decompress the actual data until it's finished. I've tested a bunch and all of the tests included pass, if any other issues arrive I'd be glad to take additional time to look into it. Includes a file, IncorrectHeaders.zip, that is a zip of a folder called IncorrectHeaders which includes a single file, Readme.txt. I've intentionally changed the header for that file to read 50 bytes intend of the actual 59 for testing purposes.	2012-05-08 22:55:30 -04:00
Sam Soffes	f6eb58cc51	Verify delegate file indexes. Closes #18 Using `zip` in Terminal generates zip files with just the files you zip. If you use OS X's archiver, it will add hidden files making the indexes appear to be wrong.	2012-05-08 09:47:56 -07:00

Sam Soffes	23426fd0de	Fixes for unzipping modification dates and add ARC support * Add ARC support * Fixes: One of the bugs is that the file modification dates for files being unzipped were wrong. Apparently the code was taking the MS-DOS date and time and treating it as an NSTimeInterval since Jan 1, 1980. This is not correct and was resulting in modification dates for me in 2014. — Brant Sears * Fixes: The second bug was that the file modification dates for folders were showing up as the current date/time, but when I unzip the same archive using Apple's implementation of zip, the file modification dates for those folders were set sometime in the past. — Brant Sears	2012-05-07 23:08:49 -07:00
