Uipopovercontroller can only be used on ipad devices; The function is to display temporary content, which is always displayed at the front of the current view, with an arrow that indicates which button is bouncing from, and disappears automatically when you click elsewhere in the interface. (1) Create two Uiviewcontroller classes (Listviewcontroller and Oneviewcontroller) Listviewcontroller as a pop-up controller view display (2) Build a pop-up view to show what it is that pops up a table.
