[Closed] iCloud iTunes Match and my iphone question

You can download from the cloud onto the phone - then they're on the phone and available offline.

I'm not sure what you mean turn the cloud off - I think you can choose to show just the music that's local on the phone rather than everything on the cloud.. not tried though.

I usually just download my jogging playlist and an album as and when I feel like it from itunes match. Don't bother turning it on and off, if I go listening to music on shuffle, I end up with a load of songs on there, but I just go into settings/general/usage and delete the Music bit every now and then.

The point of the cloud is it gives you the option of downloading at any time, it is, by default, 'on' all the time you have a data connection. The only way you could turn it off is to turn on Airplane option, as far as I know. Unless you're streaming, but I don't think that's all that practical.
That's as I understand how it functions. I don't use it, myself, as I won't let it downsize my ripped files, and I've got lots of those.

If you switch off match doesn't it delete the music from your phone?

Yes, go into Settings>Music and uncheck the "show all music" option. That will leave only the tracks you have downloaded available to view in the Music app. When you want to download another track, just flick that switch back on.

If you turn off iTunes cloud then it usually deletes everything...
