objective c - How do I find information on other applications running on the computer on Mac/Cocoa/Obj-C?

Question

I want to find which applications are running, particularly I want to know which one has a window that has focus. So at any given time I want the app to know which application the user is actively working with. I can't figure out how to determine which app is selected, I can only see which window they are using in my app using keyedWindow. If they are not in my app it just becomes 'null'

What would be nice is if I could get the application name, and the title of the window (if possible)

Apologies, I found what I needed. If anyone is looking to do this same thing, this snippet should help:

NSDictionary *activeApp = [[NSWorkspace sharedWorkspace] activeApplication];
NSLog(@"Active application is: %@", (NSString *)[activeApp objectForKey:@"NSApplicationName"] );
