Electron MAC docker 栏图标设置

Mac OS 需要通过 app.dock.setIcon 进行设置。

function createWindow() {
    mainWindow = new BrowserWindow({
        width: 800,
        height: 600,
        webPreferences: {
            nodeIntegration: true
        },
        icon: path.join(__dirname, 'assets/images/facetime.png')
    });
    
  if (process.platform === 'darwin') {
      app.dock.setIcon(path.join(__dirname, 'assets/images/facetime.png'));
  }

    mainWindow.loadFile('index.html');

    mainWindow.on('close', function() {
        mainWindow = null;
    });
}
