使用LSUIElement（又名Dock图标）但保留“文件，编辑，查看”菜单栏？

Question

I want my app to have:

• Menubar extra icon (by the clock)
• App Menubar ("File, Edit, View, Etc")

I do not want my app to have:

• Dock Icon

Is this possible? I am deploying for 10.6 and 10.7 via the Mac App Store if that matters.

Setting LSUIElement in the info.plist file removes the dock icon, but it also removes the menubar.

Answer 1

NSApplication's setActivationPolicy might be what you are after.

[NSApp setActivationPolicy:NSApplicationActivationPolicyAccessory];

Please note the discussion:

Currently, NSApplicationActivationPolicyNone and NSApplicationActivationPolicyAccessory may be changed to NSApplicationActivationPolicyRegular, but other modifications are not supported.Needs links to running application

As per NSApplicationActivationPolicyAccessory's documentation you may need to programmatically ensure that the menu bar appears.

Answer 2

You could create two "separate" applications. One that has a dock icon and menu items,the other one has just the icon by the clock. When you click on the icon by the clock it launches the dock application. When you close the dock application the 'background' application stays running.

If that model will work for you then that's the way to go. But I would weigh that effort against what File-Edit-View will do for you.
