Now I know that xCode automaticly does the GZip decrompession for you within:
NSData *data = [NSData dataWithContentsOfURL:URL];
And it doe
If you download something with content type application/x-gzip, the url loading system will not decompress it for you. I think the data
that you received is still gzip encoded.
You can use my NSData additions to deal with this. See http://github.com/st3fan/cocoa-utils/blob/master/src/NSDataGZipAdditions.m
