Questions & Answers

I have a game that creates drawings.

I need to have a button which sets the drawing as the wallpaper (with permission from the user of course).

Is it possible?

Have you considered saving the drawing as an image and letting the user set the image as the wallpaper?

The reason i ask is: Example or Example

No, only the user can change their wallpaper using the Settings app. The best you can do is save a texture to their Camera Roll and direct them to change it.
