PortOfLZMA

Port of LZMA SDK for iOS / Android.

##LZMA LZMA is the default and general compression method of 7z format in the 7-Zip program. LZMA provides a high compression ratio and very fast decompression, so it is very suitable for embedded applications. For example, it can be used for ROM (firmware) compressing.

##Status This project is the port of lzma for iOS , Android and Linux , Windows platforms.

For iOS: I have already tested on my iphone5s and the simulator 6SP. The iOS version i have developed only for one day, so if you use it in your production project, please tested more.

The compressed file can be decompress on Win7 by the 7-Zip program( download from http://www.7-zip.org/a/7z1512.exe ).

For linux/OSX: I have tested using the files in LzmaCompressUnixC.

##Usage Add the LzmaCompressIOS folder to your project, and enable BITCODE.

[LzmaCompress compress:outFile
            outputFile:outFile2
           blockSucess:^(){
               NSLog(@"---- Compress sucess");
           }
          blockFailure:^(){
              NSLog(@"#### Compress failed");
          }

[LzmaCompress decompress:inFile
            outputFile:outFile
            blockSucess:^(){
                 NSLog(@"---- Decompress sucess");
            }
            blockFailure:^(){
                NSLog(@"#### Decompress failed");
            }

##TODO 1 Android support

2 Stream compress/decompress support (byte array). For now, PortOfLZMA only support file compress/decompress.

3 Cocopods support

4 Optimize memory usage

5 LZMA2 support

6 MS-Windows support
