应用程序的系统级热键 [英] System-wide hotkey for an application

问题描述

我有一个简单的窗口，有3个按钮，我试图添加一个系统范围的热键，所以我可以按那些按钮，而不必切换到该应用程序，按一个按钮，然后回到我的

I have a simple window with 3 buttons and I am trying to add a system-wide hot key so i can "press" those buttons without having to switch to that app, press a button and then go back to what I was doing.

像 Cmd + Shift + 1 kbd> Cmd + Shift + 2 按钮2等。

Something like Cmd + Shift + 1 press button 1, Cmd + Shift + 2 press button 2, etc.

在Cocoa（用Objective-C）实现这一点？
谢谢，代码是非常感谢，因为我是Cocoa的新手。

Is there any way to achieve this in Cocoa (with Objective-C)? Thanks, code is appreciated since I am a total newbie on Cocoa.

推荐答案

我也不喜欢PTHotKey ，所以我最后写了一个新的封装，可在这里：

I also didn't like PTHotKey, so I ended up writing a new wrapper, available here:

编辑

您需要的2个文件是：

• DDHotKeyCenter.h


• DDHotKeyCenter.m

• DDHotKeyCenter.h
• DDHotKeyCenter.m

使用它像这样：

- (IBAction) registerHotkey:(id)sender {
  DDHotKeyCenter * c = [[DDHotKeyCenter alloc] init];
  if (![c registerHotKeyWithKeyCode:kVK_ANSI_1 modifierFlags:(NSCommandKeyMask | NSShiftKeyMask) target:self action:@selector(hotkeyWithEvent:) object:nil]) {
    NSLog(@"unable to register hotkey");
  } else {
    NSLog(@"registered hotkey");
  }
  [c release];
}

- (void) hotkeyWithEvent:(NSEvent *)hkEvent {
  NSLog(@"Hotkey event: %@", hkEvent);
}
