这可以:

CFArrayRef windowList = CGWindowListCopyWindowInfo(kCGWindowListOptionOnScreenOnly, kCGNullWindowID);
NSLog(@"%@", (__bridge NSArray *)windowList);

这会导致EXC_BAD_ACCESS:

CFArrayRef windowIDList = CGWindowListCreate(kCGWindowListOptionOnScreenOnly, kCGNullWindowID);
NSLog(@"Array %@", (__bridge NSArray*) windowIDList);
