photoshop how to load and execute the plugin on mac?

[as0101010101]

my code like this, to load plugin and run function in bundle.

   if (g_bundlePath == nullptr) {
        g_bundlePath = CFSTR("/Applications/test.plugin");


        CFURLRef bundleURL = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, g_bundlePath, kCFURLPOSIXPathStyle, true);
        g_bundle = CFBundleCreate(kCFAllocatorDefault, bundleURL);

        if (g_bundle) {
            bool success = CFBundleLoadExecutable(g_bundle);
        }

    }

    if (g_bundlePath != nullptr) {
        typedef void (*PLUGINPROC)(const int16, void*, intptr_t*, int16*);
        PLUGINPROC mainProc = (PLUGINPROC)CFBundleGetFunctionPointerForName((CFBundleRef)g_bundle, CFSTR("PluginMain"));
        mainProc(selector, filterRecord, data, result);
    }
    return ;

but those icons in resource directory cant display on ui, is there any problem my code?

You seem to be mixing up plug-ins with executables. You do not load Photoshop plug-ins. You do not run Photoshop plug-ins. Photoshop plug-ins are not installed in /Applications.

Photoshop plug-ins are installed into a Photoshop plug-ins folder. They are loaded by Photoshop. They are run by Photoshop, for example when the user chooses a filter or a menu.

Yes, as you said, I saw an executable file in the plugin directory. Photoshop cant run the plugin,so Im doing some tests.  May I ask if the method I used to load this executable file is correct? Why can't I load the resource file display on UI?
