I've just re-done about 100 trial on Tim's tutorial. Finally I made it work. Although I swear it worked when I first time tried it. In my situation is when I switch "Launch at login" to On, I can only see the helper app launched for just one second right after login. Then it was gone. Manually start the app, I saw the switch was turned off.

Here was what I found:

1. my bundle identifier was already in the list of NSArray *running = [[NSWorkspace sharedWorkspace] runningApplications]
2. the status of the NSRunningApplication *app (bundle name equal to my app) is: [app isActive] == NO, [app isHidden] == NO, [app isTerminated] = NO

So I made some modification to the code like:

BOOL alreadyRunning = NO;
BOOL isActive = NO; // my modification
NSArray *running = [[NSWorkspace sharedWorkspace] runningApplications];
for (NSRunningApplication *app in running) {

    if ([[app bundleIdentifier] isEqualToString:@"com.mybundleidentifier"]) {
        alreadyRunning = YES;
        isActive = [app isActive]; // my modification
    }
}

if (!alreadyRunning || !isActive) { // my modification
  ....
