Can I switch between creativr and survival mode in MineCraft PS3 Edition?

I wana fight my friends to see who the better PvPer is but I wana make a pvp arena. I wana spawn in the armor and the swords etc. And I want that to be like our PvP world. So this is why I wana switch back and forth.

When you load up your game you can always switch between creative and survival, however, once done it'll turn off trophies. There isn't a button to do this in game, which a lot of people find really irritating. I suggest first going into your world in creative, putting out enough armor and materials you need in chests, then switching it back to survival for the pvp.
