Open Pages on your iPhone and press the « + » button in the upper left corner to display the screen on the left side below, then select « WebDAV ». Then it becomes a screen of the right side, and input « https://dav.dropdav.com/ » in the place of the server address, and put the user name and the password that I made on DropDAV a while ago, and sign in.
That’s all there is to it. Once you’ve signed in without any problems, you’ll see your Dropbox folders appear as you can see. All you have to do is open each iWork file.
