如何保存焦点上下文并在OSX应用程序中返回焦点上下文？

Question

I'm writing a menubar application that shows a window when a global hotkey is pressed. The application has no dock icon and no normal menu (just the statusItem).

Prior to activating the application, lets say I have a text box on a webpage in chrome focused. How can I refocus that text box when my application is dismissed.

If you're familiar with Text Expander, they do something similar.

I figured this out. You need an NSRunningApplication:

@implementation AppDelegate { NSRunningApplication *_previousApplication; }

Then store the previous application before you become active:

_previousApplication = [[NSWorkspace sharedWorkspace] frontmostApplication];

Finally, after you deactivate, just bring back the other application:

[_previousApplication activateWithOptions:NSApplicationActivateIgnoringOtherApps];
