I need to create a big table to csv file and compress it.

I can create the csv file like this: Xcode - Create csv/spreadsheet file

It is possible compress it with GZIP?

Thanks for all.

Answer 1

I recommend you use SSZipArchive: https://github.com/soffes/ssziparchive

Then you can do:

NSString *content = @"1,2,3"
NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:@"somefile.zip"];
SSZipArchive *zip = [[SSZipArchive alloc] initWithPath:path];
[zip open];
[zip writeData:[content dataUsingEncoding:NSUTF8StringEncoding] filename:@"data.csv"];
[zip close];

That will produce a zip file named "somefile.zip" in the temporary directory, containing one file inside named "data.csv"

最简单的方法可能是不使用标准的复制构建阶段将文件移动到位，而是使用Shell脚本构建阶段复制文件，然后使用gzip将其压缩到位。
