The extension Share when we created it, is automatically created one file called mainInterface.storyboard, which in this case seems to be a kind of custom screen for the share Extension.
In my case I changed this screen and to my surprise when I select my application to give share, it besides pulling the custom screen, it also commonly pulls the original screen on the share (that with the text field two buttons).
How can I make to no push original screen, but push the custom screen?
