Do you mean, you want to delete certain photos from your iPhoto Library on your IOS device?
Photos that have been synced to iPhoto need to be removed on the device you are syncing from, then sync again. Photos that you imported from mail or the camera roll can be deleted using the menu:
See this manual page: Delete photos and this thread:
If you edited a photo you need to revert the edits, before you can remove it. Otherwise it will stay in the "Edited" album.
