应用程序的系统范围热键 [英] System-wide hotkey for an application

问题描述

我有一个带有 3 个按钮的简单窗口，我正在尝试添加一个系统范围的热键，这样我就可以按下"这些按钮而不必切换到该应用程序，按下一个按钮，然后回到原来的状态

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.

类似于 Cmd + Shift + 1 按下按钮 1，Cmd + Shift + 2 按下按钮 2 等

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

有什么办法可以在 Cocoa 中实现这一点(使用 Objective-C)?谢谢，感谢代码，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，所以我最终编写了一个新的包装器，可在此处获得:

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:

The 2 files you'd need are:

• DDHotKeyCenter.h
• DDHotKeyCenter.m

你会像这样使用它:

- (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);
}
