objective-c – 如何实现基于Cocoa的Adobe Photoshop插件

在CS3上工作,从Carbon加载它并发出NSApplicationLoad().那是因为Photoshop CS3只是Carbon并用于卸载插件包.

Photoshop CS4使用Cocoa并在主线程上有自己的NSAutorelease池.

在Photoshop CS4上,由NSWindowController加载的非常简单的基于窗口的xibs / nib工作开箱即用.

但是只需在窗口上添加一个绑定到控件上就可以了,当你关闭窗口时,或者第二次使用插件时,或者甚至在关闭Photoshop本身时,你都会遇到有趣的崩溃.

为什么一切似乎都运行良好,直到我使用一些高级Cocoa功能？我被卡住了.

编辑：我真的发现自己解决了更广泛的问题“如何在Photoshop CS3 / CS4插件中使用Cocoa？”.见下文.

Boolean DoUI (void) {

    // Create the CF Cocoa bundle
    CFBundleRef pluginBundle;
    CFURLRef cocoaBundleURL;
    pluginBundle = CFBundleGetBundleWithIdentifier(CFSTR("com.example.plugin"));
    cocoaBundleURL = CFBundleCopyResourceURL(pluginBundle, 
                                             CFSTR("Cocoa_bundle"), 
                                             CFSTR("bundle"), 
                                             NULL);
    CFBundleRef cocoaBundleRef;
    cocoaBundleRef = CFBundleCreate(kCFAllocatorDefault, cocoaBundleURL);
    CFRelease(cocoaBundleURL);

    // start Cocoa (for CS3)
    NSApplicationLoad(); 

    NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];

    // load the cocoa bundle by identifier
    NSBundle* cocoaBundle;
    cocoaBundle = [NSBundle bundleWithIdentifier:@"com.example.plugin.cocoa"];

    // load the window controller from the bundle
    Class testControllerClass;
    testControllerClass = [cocoaBundle classNamed:@"MyWindowController"];

    MyWindowController* winController = [[testControllerClass alloc] init];
    [NSApp runModalForWindow:[winController window]];
    [[winController window] performClose:nil];
    [winController release];

    // release the bundle
    CFRelease(cocoaBundleRef);

    [pool release];

    return 1;
}

这是基于Craig Hockenberry bundle trick .我还在测试它,但它应该适用于CS3和CS4.
