问题 Since the Finder in Snow Leopard has been rewritten to use Cocoa instead of Carbon, I'd like to know if there's a new API to write Finder plugins. The old way involved writing a CFPlugin but this doesn't seem to work anymore. 回答1: If by plug-in you mean contextual menu, you can do this via the services API. 回答2: I believe they prefer that you write Services instead of Finder plugins now. 来源： https://stackoverflow.com/questions/1651075/finder-plugin-in-snow-leopard

问题 For Windows there is Win32 API, what about for Mac? On Wikipedia http://en.wikipedia.org/wiki/Cocoa_(API) it is said that Cocoa is "one of" the API... what about the full story? 回答1: At what level? The low level API is largely but not entirely FreeBSD, and below that there is still a Mach API (some things still use Mach ports for IPC, I believe; at least, launchd supports them). At the upper level are two APIs: Cocoa and Carbon. Cocoa is the native API; Carbon is intended for programs ported

问题 Signing (codesign) on one of our app is failing with malformed object (unknown load command 9) . After doing some research online I found that load commands are special commands in executable's header that are used by kernel for segment loading ( http://0xfe.blogspot.in/2006/03/how-os-x-executes-applications.html ).

问题 When I access the satimage.osax scripting addition (which I'm using for its regex capability) from a Mail rule on Snow Leopard, I get errors, but it runs fine in Script Editor.

问题 I am looking for a way to show/hide desktop icons programmatically in objective-c under Mac OS X. Do you have any idea on how I can achieve this? Thanks for your help, Regards, 回答1: The Finder has a hidden preference for this. Set the value of CreateDesktop under com.apple.finder to kCFBooleanFalse , then kill the Finder. To put the desktop icons back, delete the CreateDesktop preference and kill the Finder again. Of course, this isn't a supported API feature; it could go away at any time.
