UIPopover without an arrow
- April 04, 2012
Ever wanted to place a UIPopover on a View but not have an arrow?
The UIPopoverDirectionArrowDirection enum is defined as
UIPopoverArrowDirectionUp = 1UL << 0,
UIPopoverArrowDirectionDown = 1UL << 1,
UIPopoverArrowDirectionLeft = 1UL << 2,
UIPopoverArrowDirectionRight = 1UL << 3,
UIPopoverArrowDirectionAny = UIPopoverArrowDirectionUp | UIPopoverArrowDirectionDown |
UIPopoverArrowDirectionLeft | UIPopoverArrowDirectionRight,
UIPopoverArrowDirectionUnknown = NSUIntegerMax
Which doesn't include UIPopoverArrowDirectionNone, or does it?
There is an undocumented feature that if you call presentPopoverFromRect with a 0 for permittedArrowDirections, it will show no arrows. I'm not sure if this is 100% supported by Apple, but a trawl around the internet suggests that apps using this have been accepted.
So call the code like below, and hey presto! No arrows
