A customizable popover controller for OS X

branch: master
README.md

INPopoverController

Open source OS X popover implementation

OS X 10.7 introduced the NSPopover class for displaying popover windows. That said, developers who want to support older versions of OS X (like me) are unable to use that API without breaking backward compatibility. So I developed this class that will allow developers to easily add popovers into their applications and also have it be compatible with older versions of OS X. I've included a sample app to demonstrate how to use INPopoverController:

INPopoverController

Features:

  • Customizable color, border color, border width, arrow size, and corner radius.
  • Automatically calculates the best arrow direction depending on screen space and popover position
  • Displays content from a regular NSViewController (can be loaded from a NIB)
  • Animation for when the popover appears/disappears and when the content size is changed
  • Popover can anchor to a view
  • Customizable popover behaviour (close when key status is lost, when application resigns active)

How to use it

The headers are well documented (and I've also included a sample app) so it should be simple to figure out how to use it. There are color, borderColor, and borderWidth properties to customize the appearance of the popover. There are also some hard-coded defines in the INPopoverControllerDefines.h file which can be changed to further customize the appearance. The closesWhenPopoverResignsKey and closesWhenApplicationBecomesInactive properties can be used to control the behaviour of the popover. Everything else should be pretty much self explanatory.

If you want to completely customize the drawing of the popover, you can edit the INPopoverWindowFrame.m file to run your own drawing code instead of the default. Make sure that you're taking the arrowDirection property into account when drawing.
