A long-press gesture displays a Context Menu, which gives the user the
ability to use cut/copy/paste operations on the selected object. By
default, the Context Menu is disabled on a Table View. In this tutorial the
context menu will be enabled to copy the text of the Table View Cell, this
text can then be pasted into a Text Field. This tutorial is made with Xcode
7 Beta 5 and built for iOS 9.
