在运行时从dock添加/删除应用程序图标？ [英] Add/remove application icon from dock at runtime?

问题描述

有没有一个公共的Apple API，它允许你在运行时删除应用程序的dock图标？
我试图通过NSApplication的dockTile替换一个零大小的空视图，但这只是擦除dock图标，而不回收其空间和启动指示器。我还知道应用程序的info.plist中的LSUIElement参数，但此值仅在启动时评估。它不是运行时参数。

Is there a public Apple API which allows you to remove an application's dock icon at runtime? I have tried substituting an empty view with zero size via NSApplication's dockTile, but that simply erases the dock icon without reclaiming its space and launch indicator. I also know about the LSUIElement parameter in an application's info.plist, but this value is only evaluated on launch. It is not a runtime parameter.

EDIT

您可以调用setActivationPolicy：NSApplicationActivationPolicyProhibited再次隐藏dock-icon

You can call setActivationPolicy:NSApplicationActivationPolicyProhibited to hide dock-icon again – user1592530 Sep 18 '12 at 14:21

这是一个单向的街道：你可以设置你的应用程序NSUIElement隐藏dock图标，然后调用 [NSApp setActivationPolicy：NSApplicationActivationPolicyRegular]; 在dock中显示它，但一旦它在那里你不能删除它。因此，您可以使dock图标成为用户可配置的，但您必须重新启动应用才能隐藏图标。

It's a one way street: You can set your app to NSUIElement to hide the dock icon, then call [NSApp setActivationPolicy:NSApplicationActivationPolicyRegular]; to show it in the dock, but once it's there you can't remove it. So you could make the dock icon user-configurable, but you'd have to relaunch the app to hide the icon.
