In my iPad application I want to implement a feature like when a user clicks on a button in the application a screenshot of the current screen should be stored in the database. I'm new to ios development, and I'm totally unaware as how to implement it. Please guide me how.
Refer this link. Here you will find code on how to take screen shot of screen.
Don't save images in database, save your images in Document Directory in iPad. Just save file name of that image in database, which will help you fetch image easily.
Hope this info helps you..
