How to get my iTunes songs onto Spotify with my iPhone or iPad?

I just recently got spotify premium. I don't have a computer, but I do have an iPhone and an iPad with all of my iTunes song on them. Is there a way for me to transfer my iTunes songs onto spotify using my iPhone or iPad, or is that something where you need a computer? And if you do need a computer, do you have any alternative suggestions since i don't have a computer?
