Best archiver library for iOS [closed]

Question

I'm looking for an archiver library to use in my iOS app (zip or other formats). What is the best library in terms of:

1. How easy it is to include it in a iOS project
2. Memory consumption
3. Speed of unarchiving
4. How stable it is

Answer 1

For file archive, until now I found these libraries

• zipzap
• SSZipArchive
• Godzippa
• ZipArchive
• objective-zip
• GZIP

(Naively sorted by todays 2013-04-16 github stars)

I only tried ZipArchive because I needed zip format and password protected archive creation. It seems to do the job pretty well until now.

Answer 2

I used Objective Zip and it worked quite well on iOS4. Work with this library is easy as this:

ZipFile *zipFile= [[ZipFile alloc] initWithFileName:@"test.zip" mode:ZipFileModeCreate];
ZipWriteStream *stream= [zipFile writeFileInZipWithName:@"abc.txt" compressionLevel:ZipCompressionLevelBest];
[stream writeData:abcData];
[stream finishedWriting];

Unzipping is done in similar fashion.

I can recommend it, but I can not provide any comparison to others. You can see on the wiki also some other libraries, which are based on this one. I hope this will help you a little.

Answer 3

ZipZap is the solution I find most appealing. It has the advantage of only depending on the zlib the SDK provides.
