JFHotkeyManager is a small Cocoa convenience wrapper around Carbon's mechanism for implementing global hotkeys. It allows you to add hotkeys to your app with a couple of lines of code.

Installation

Copy JFHotkeyManager.h and JFHotkeyManager.m into your Xcode project

Usage

Hotkeys can be bound either by individually specifying keycode/modifiers, or symbolically using a string. The latter is more convenient but probably less reliable across international keyboards.

// Initialise a new hotkey manager
JFHotkeyManager *hkm = [[JFHotkeyManager alloc] init];

// Bind a hotkey by key code reference number and modifiers:
// (when hotkey is triggered, sends mySelector1 to self)
[hkm bindKeyRef:49
  withModifiers:cmdKey + optionKey + shiftKey
         target:self
         action:@selector(mySelector1)];

// Bind a hotkey symbolically
// (when hotkey is triggered, sends mySelector2 to self)
[hkm bind:@"command shift up" target:self action:@selector(mySelector2)];

The bind methods return an opaque value of type JFHotKeyRef that can be latter passed to unbind: to unbind the hotkey.
