Animated Wallpaper Development for iPhones

I an interested in making animated wallpaper apps for the iPhone. This means that, once I click the app to open, it should not open up a view, and it should change the current wallpaper of the iPhone to the an animated wallpaper(which I have designed), while th开发者_StackOverflowe App is running.

If I close the app, it should bring the iPhone back to the initial wallpaper.

  1. How do I go about this ?
  2. How can I modify changes to the wallpaper of the iPhone with my app.
  3. How can I place my customized wallpaper in a way that the iPhone operates normally and you can scroll to other apps and stuff while the background wallpaper is animated ?
  4. What tools are needed for that animation ?


If I understand you correctly, you want to create an application that swaps out the background wallpaper.

This can only be a jail broken app.

We do not have access to the springboard wallpaper on a normal device with the SDK. So this type of app can only be a jail broken app an a jail broken device and in a jail broken marketplace.

  1. The methods you should implement are pretty simple. Would probably be an NSTimer that chooses randomly from an array of image names and sets the background wallpaper.

  2. I do not know the immediate functions to use, and they are probably undocumented.

  3. Background process app that is always running (like Mail).

  4. In the function the timer calls, just make a UIView animation block that shifts the previous image where ever you want and shifts the new one into the view.

What I would suggest is get the functionality you want running in a project. Once that is all done, look into making it a jail broken app and running in the background (this is probably going to be the bulk of the work, and really really hard)


Currently you can not change a users wallpaper programatically, file a feature request with apple like many of us have :)...However you can do it on jailbroken phones...
