I've got a file, bigfile.gz, in the bundle of my iPhone app. At app start, I want to gunzip that file to my Documents directory within my app. How can I achieve this programmatically?
Basically I want the effect of: gunzip bigfile.gz.. obviously a gunzip utility is not available in the iOS environment though.
As pointed out in this post:
both zlib and bzip2 are available. However, as another answer there points out, if you store the data for the conversations in an NSData object, then you can use an NSData category that adds gzip and zlib compression / decompression as simple methods. Here's a useful link for that.
