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

Question

What is this error indicate "Popovers cannot be presented from a view which does not have a window."

Answer 1

the view you're adding the popover to has to already have been added to a window with the "addSubview:" method.

Try waiting until

- (void) didMoveToWindow

is called for the view and then load the popover

Answer 2

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.
