A:

That can be possible, Once I found something that does the same as you wanted.  But I would like you to read these line that the author wrote a the beginning of that post:
The content of this post is for debugging and testing only.  Do not submit this code in an application to the App Store.  Doing so will likely result in:

A bad UI experience for your users. 
An app that breaks on every OS update. 
Rejection of your application.
