I have a lot of jpeg+png+html files to add to my app, and of course when i "build" it all my resources files are added/included in myApp mainBundle folder.

I'd like to be able to modify via code, in run time, some of my resources, but:

1) we cannot "write" files via code in run-time in mainBundle

2) we can do it just in "documents" folder (or temp, or...)

3) we can copy files in "Documents" folder just via code in run-time

4) we cannot delete the mainBundle files after coping them in "Documents"

but that means that we will have doubled-sized our app, and in big apps (it's my case) this should be a non-sense, we'll have a lot of big files never used again in the mainBundle...

so i wondered if there was a work-around for this problem (is it just me thinking it's a non-sense?) to add files directly in the "Documents" folder in the "build" phase via xCode, or other similar solutions...

ps

one could be to download all files the first time a user use my app via server/internet directly in "Documents" folder, so my app won't be heavy to download via iTunesStore, but of course this will get a lot of time the first time for end-users, and it could be not well accepted, of course...
