问题描述
我试图创建一个在执行时不打开窗口的实用程序，它将从热键激活;我读到当前Cocoa没有一个函数，我应该使用一个已弃用的Carbon函数。
I am trying to create a utility that doesn't open a window when executed, and that would be activated from a hot key; I read that currently Cocoa doesn't have a function for that, and that I should use a deprecated Carbon function.
没有真正的方法使用全局热可可钥匙？我应该怎么做：等待Cocoa引入一个函数，或者使用碳函数，直到在Cocoa中没有引入类似的函数。
Isn't there really a way to use global hot keys in Cocoa? What should I do: wait for Cocoa to introduce a function for that, or use the carbon function until a similar function is not introduced in Cocoa?
推荐答案
使用。 此功能在64位中支持（注意，它缺少在64位可用性说明中不可用）。
Use the Carbon Event Manager's RegisterEventHotKey function. This function is supported in 64-bit (notice that it lacks the "not available in 64-bit" availability note).
NSEvent的新的 addGlobalMonitorForEventsMatchingMask：handler：方法在Snow Leopard是不是实现热键的最简单的方法。首先，它要求用户具有访问辅助设备的权限;此外，它需要你自己检查每个事件，与 RegisterEventHotKey 系统相比，它只调用您的回调函数，当用户按您注册的特定键。
Conversely, NSEvent's new addGlobalMonitorForEventsMatchingMask:handler: method in Snow Leopard is not the easiest way to implement a hot-key. For one thing, it requires that the user have access for assistive devices turned on; moreover, it requires you to examine every event yourself, as compared with the RegisterEventHotKey system, which only calls your callback function when the user presses the specific key you registered for.
