Popovers cannot be presented from a view which does not have a window

Question

What does this error indicate:

\"Popovers cannot be presented from a view which does not have a window.\"

Answer 1

Just encountered this issue. Turned out that the inView: parameter was using an IBOutlet that wasn't connected in IB. Thus, an attempt was made to launch the popover in nil. That doesn't work.

So, make sure you are using a valid view.
