Quartz Display Services replacement for deprecated functions

techgentsia · Jan 30, 2013, 02:19 AM

The method CGWaitForScreenRefreshRects is deprecated in Mac OS X v10.8. The alternative method mentioned in class reference(CGRegisterScreenRefreshCallback) is also deprecated.

What should I use to get the screen updates in 10.8?
Someone please help me.

Why do you need this data? What are you trying to do?

Thanks for responding. I am trying a desktop sharing application for which I need a method which returns the screen changes/updates. The method I use works, but is deprecated in 10.8. No replacement mentioned in reference manuel.

Have you tried looking into the APIs that Quartz Debug uses? Try looking at the symbols using "nm -mp" from the terminal. There may be some API whose name looks promising.

For some reason I think AV Foundation has what you're looking for. I recently watched a WWDC, 2012 I think, video about it and they mention screen captures for Mac OS.
