addGlobalMonitorForEventsMatchingMask在某些计算机上不工作

我使用这个代码在我的应用程序中捕获全局键盘快捷键。

I'm using this code to capture Global Keyboard Shortcuts in my app.

这几乎在我运行它的每台计算机上都工作得很好。我试了一个全新的Retina Macbook Pro本周， addGlobalMonitorForEventsMatchingMask 根本不工作。它甚至不记录每个键，像我已经设置为这里做调试。

This works great on almost every computer I run it on. I tried it on a brand new Retina Macbook Pro this week and addGlobalMonitorForEventsMatchingMask doesn't work at all. It doesn't even log every key like I have it set up to do here for debugging.

有更可靠的方法吗？现在我加载到 applicationDidFinishLaunching 。

Is there a more reliable way to do this? Right now I load this on applicationDidFinishLaunching.

我认为加载它作为自己的方法更有意义在App Delegate中，但我不知道它的语法将是什么样子。

I think it might make more sense to load it as its own method in the App Delegate but I'm not sure what the syntax of that would look like.

[NSEvent addGlobalMonitorForEventsMatchingMask:NSKeyDownMask handler:^(NSEvent *event){

    NSLog(@"sequence = %li", (unsigned long)[event modifierFlags]);

    // Activate app when pressing cmd-c
    if([event modifierFlags] == 1048840 && [[event charactersIgnoringModifiers] compare:@"c"] == 0) {
