Qt MacOS创建程序的快捷方式代码

在 macOS 上创建程序的快捷方式可以通过以下代码实现：

#include <QtCore>
#include <CoreFoundation/CoreFoundation.h>

void createShortcut(const QString &appName, const QString &appPath)
{
    // 获取应用程序的 bundle identifier
    CFStringRef bundleIdRef = CFStringCreateWithCString(kCFAllocatorDefault, 
                                                         qPrintable(appName), kCFStringEncodingUTF8);
    CFBundleRef bundleRef = CFBundleGetBundleWithIdentifier(bundleIdRef);
    CFRelease(bundleIdRef);
    
    // 获取应用程序的可执行文件路径
    CFURLRef appUrlRef = CFBundleCopyExecutableURL(bundleRef);
    char appPathCStr[PATH_MAX];
    CFURLGetFileSystemRepresentation(appUrlRef, true, (UInt8*)appPathCStr, PATH_MAX);
    CFRelease(appUrlRef);
    
    // 创建快捷方式
    CFStringRef pathRef = CFStringCreateWithCString(kCFAllocatorDefault, qPrintable(appPath), kCFStringEncodingUTF8);
    CFURLRef pathUrlRef = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, pathRef, kCFURLPOSIXPathStyle, false);
    CFRelease(pathRef);
    
    CFStringRef appNameRef = CFStringCreateWithCString(kCFAllocatorDefault, qPrintable(appName), kCFStringEncodingUTF8);
    CFURLRef shortcutUrlRef = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, appNameRef, kCFURLPOSIXPathStyle, true);
    CFRelease(appNameRef);
    
    CFErrorRef errorRef = NULL;
    if (!LSRegisterURL(pathUrlRef, true, &errorRef)) {
        qDebug() << "Create shortcut failed:" << errorRef;
        CFRelease(shortcutUrlRef);
        CFRelease(pathUrlRef);
        return;
    }
    
    if (CFURLWriteDataAndPropertiesToResource(shortcutUrlRef, NULL, NULL, &errorRef)) {
        qDebug() << "Create shortcut succeeded:" << appPath;
    } else {
        qDebug() << "Create shortcut failed:" << errorRef;
    }
    
    CFRelease(shortcutUrlRef);
    CFRelease(pathUrlRef);
}

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
    
    createShortcut("org.qt-project.QtCreator", "/Applications/TextEdit.app");
    
    return app.exec();
}

在上面的代码中，`createShortcut` 函数接收两个参数：应用程序的名称和应用程序的路径，然后通过 Core Foundation 库中的函数创建快捷方式。
