Valid file types for iCloud?

Question

I find many similar question but i didn't get solution for this.

Is it possible to upload some file like image, document, zip file to upload on iCloud programmatically?

Answer 1

See table 4-1 in the documentation:

How do you manage the data? Manage files and directores using the NSFileManager class. Open, close, read, and write files using standard file system routines.

So if you can create a file, you can store it in iCloud. But remember there's a finite, relatively small amount of space available.
