I'm curious if its possible to change the system wallpaper/background for an iOS device programmatically from your own application.

推荐答案

Apple没有为此提供公共API.用户必须通过设置"应用选择要用作墙纸的图片.

Apple doesn't provide a public API for doing this. The user must select the picture to use as the wallpaper via the Settings app.

您可以使您的应用将图片保存到用户保存的照片中，并指示用户手动更改壁纸.

You can make your app save pictures to the user's saved photos, and instruct the user to change the wallpaper manually.
