How to programmatically focus Desktop/Finder via Mac App?

Question

I want to focus Desktop/Finder via my App, especially if the user is currently inside a fullscreen application. I've been trying to use stuff like:

[[NSWorkspace sharedWorkspace] launchApplication:@"Finder"];

and

[[NSWorkspace sharedWorkspace] openFile:nil withApplication:@"Finder"];

But using these lines of code, a new Finder window will open "All Files".
I just want to focus the Desktop/Finder, how can I do that? Looking for App Store-ready code.
Thanks!

Answer 1

you can do it using cocoa's NSWorkspace - no special entitlements needed

NSArray *apps = [[NSWorkspace sharedWorkspace] runningApplications];

for (NSRunningApplication *app in apps) {
    if([app.bundleIdentifier.lowercaseString isEqualToString:@"com.apple.finder"]) {
        [app activateWithOptions:NSApplicationActivateAllWindows|NSApplicationActivateIgnoringOtherApps];
        break;
    }
}
