一个应用程序的全系统热键

问题描述：

我有3个按钮一个简单的窗口，我尝试添加一个全系统热键，所以我可以preSS，而无需这些按钮切换到该应用程序，preSS一个按钮，然后回去我在做什么。

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 Cmd的骨节病> + 移骨节病> + 1 骨节病> preSS按钮1， Cmd的骨节病> + 移骨节病> + 2 骨节病> preSS按钮2，等等。

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

有什么办法可可实现这一目标（与Objective-C的）？
谢谢，code是AP preciated因为我可可总新手。

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

答

我也不喜欢PTHotKey，所以我最后写一个新的包装，可在这里：

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

修改

2档你需要的是：

DDHotKeyCenter.h

DDHotKeyCenter.m

DDHotKeyCenter.h
DDHotKeyCenter.m

和你使用它是这样的：

- (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);
}
