I missed the beginning of this thread, so I apologize up front if my
answer is ~not~ to the question raised.
I had to do this recently for a Finder plugin that I am working on. Not
really wanting to mess with Carbon,
I had to figure out how to load Cocoa nibs.
It is (somewhat) trivial to do from Carbon applications. You need to
keep in mind
that any method you will be calling from Carbon that is defined in the
Cocoa bundle WILL need
a C wrapper.
On the carbon side of the application you need to do something like
this to load the Cocoa bundle:
static void loadCocoaBundle(CFStringRef framework, CFBundleRef
*bundlePtr)
{
CFBundleRef pluginBundle = NULL;
CFURLRef baseURL = NULL;
CFURLRef bundleURL = NULL;
pluginBundle = CFBundleGetBundleWithIdentifier( CFSTR("SVN_CMM") );
require(pluginBundle, CantFindMainBundle);
//Note that is the Bundle is somewhere other than the resource's
directory, you
//will need to use the appropriate function to get the correct URL
baseURL = CFBundleCopyResourcesDirectoryURL(pluginBundle);
require(baseURL, CantCopyURL);
bundleURL =
CFURLCreateCopyAppendingPathComponent(kCFAllocatorSystemDefault,
baseURL, CFSTR("CocoaBundle.bundle"), false);
require(bundleURL, CantCreateBundleURL);
bundleRef = CFBundleCreate(NULL, bundleURL);
CFRelease(bundleURL);
CantCreateBundleURL:
CFRelease(baseURL);
CantCopyURL:
CantFindMainBundle:
return;
}
Once the bundle is loaded, to use it do something like this:
static OSStatus SVNPluginHandleSelection(void* thisInstance, AEDesc*
inContext, SInt32 inCommandID )
{
OSStatus errorCode = noErr;
OSStatus (*initializeBundlePtr)(void);
void (*setArgumentsPtr)(CFArrayRef files);
void (*setCommandPtr)(int command);
void (*performOperationPtr)();
loadCocoaBundle(CFSTR("SCPluginCocoaBundle.bundle"), &bundleRef);
initializeBundlePtr = CFBundleGetFunctionPointerForName(bundleRef,
CFSTR("initializeBundle"));
errorCode = (*initializeBundlePtr)();
setCommandPtr = CFBundleGetFunctionPointerForName(bundleRef,
CFSTR("setCommand"));
(*setCommandPtr)(inCommandID);
setArgumentsPtr = CFBundleGetFunctionPointerForName(bundleRef,
CFSTR("setArguments"));
(*setArgumentsPtr)((CFArrayRef)filesForCommand);
performOperationPtr = CFBundleGetFunctionPointerForName(bundleRef,
CFSTR("performOperationOnFiles"));
(*performOperationPtr)();
[pool release];
return 0;
} // TerminalHerePluginHandleSelection
For a further example, look at SCplugin. The source is browse-able at
http://svn.red-bean.com/scplugin/trunk
In particular look at the SCPlugin.m class.
Cheers,

NSApplicationLoad();
Unfortunately, this is in Cocoa.framework. I can't even load a
plug-in that links to Cocoa.framework for some reason.
check out Apple cocoa spelling check sample code.
you can manually load cocoa frame work, find NSApplicationLoad()
symbol and call it.
