You can use ZipArchive, a private third party class to archive and extract the file.

And, the usage of ZipArchive can be found here.

Thanks But Also tell me that Is this a good way to store file in app in this way like Videos or images etc. – Syed Sharjeel Ali May 07 '14 at 11:34
Ofcourse, you could archive the file(an image or a video) and store that in documents folder of your app. But, your app may have the possibility to consume more memory in future times as usage of the app goes on. – Shiva Kumar Ganthi May 07 '14 at 11:44

You can do this by using ZipArchive

Here is the complete tutorial for zip and unzip file.

http://transoceanic.blogspot.in/2011/07/compressuncompress-files-on.html

Uncompress zip file example:

NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

NSString *zipFilePath = [documentsDirectory stringByAppendingPathComponent:@"myZipFileName.zip"];

NSString *output = [documentsDirectory stringByAppendingPathComponent:@"unZipDirName"];

ZipArchive* za = [[ZipArchive alloc] init];

if( [za UnzipOpenFile:zipFilePath] ) {
    if( [za UnzipFileTo:output overWrite:YES] != NO ) {
        //unzip data success
        //do something
    }

    [za UnzipCloseFile];
}

[za release];
