问题
I want to make an ios app that changes the wallpaper, lockscreen and app icons. I have googled it a lot and got same ans that apple doesn't allow this. But on itunes I saw a app named "magic theme" which does this. Here is the link.
Can someone tell me the trick how can I do this in my app?

This is not possible. The app your link provides is for creating / designing or modifying existing wallpapers. Changing apps icons is also not possible. Read the apps description carefully and try it yourself so you see what it does.
For things like changing icons and wallpapers you'd need to jailbreak your device and roll your app using Cydia.
