How can a Popup like the "Select Wi-Fi Network" alert be implemented

Question

In iOS, a popup is shown from time to time that asks the user to join a Wi-Fi network.

I want to implement a similar popup with custom contents

• Title
• TableView with a varying amount of entries (if too many, with scrollbar)
• Cancel button

• Popup over an existing view (the popup is smaller than the view)

• How can such an effect be achieved? I guess that UIAlertView may be a good starting point. However, UIAlertView does not support subclassing

  The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

Answer 1

Check this out, it is exactly the thing you need: github example project

Answer 2

Not with the system UIAlertView. You have to code your own, or use an open source component.

This could be a starting point/example: BlockAlertsAnd-ActionSheets
