I have an UIPopoverController that has to shows with the arrow direction up, but when I try to show popover in the bottom of view I see this:

[popoverController presentPopoverFromRect:[sender frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
You need to use
UIPopoverArrowDirectionDownin this case. Since the button is in the bottom area of the view, if you want to show the popover below the button (that is whatUIPopoverArrowDirectionUpsuggests implicitly), it doesn’t have any space to show the pop over.If you use
UIPopoverArrowDirectionAny, then iOS automatically figures out which way it can extend.
