Hello asahiart, I don't have an iPhone but this may help in exporting without a background. Firstly, you need to set your canvas to cell. You will find this here - Canvas Settings/Special/Cell. This gives you a canvas without a background. Then when exporting you should choose .png and not .jpg. As I said I don't know about exporting to an iPhone as I use Android and have never tried to do this. I hope this helps.
