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 the App is running.
If I close the app, it should bring the iPhone back to the initial wallpaper.
- How do I go about this ?
- How can I modify changes to the wallpaper of the iPhone with my app.
- 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 ?
- 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.
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.
I do not know the immediate functions to use, and they are probably undocumented.
Background process app that is always running (like Mail).
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)
