LaunchAtLoginController

A very simple to implement Controller for use in Cocoa Mac Apps to register/deregister itself for Launch at Login using LSSharedFileList.

It uses LSSharedFileList which means your Users will be able to check System Preferences > Accounts > Login Items.

I'm currently using it on 10.6 (32/64) successfully. I've not investigated being able to flag the "Hide" flag which is possible from System Preferences.

IMPLEMENTATION (Code):

Will app launch at login?

LaunchAtLoginController *launchController = [[LaunchAtLoginController alloc] init];
BOOL launch = [launchController launchAtLogin];
[launchController release];

Set launch at login state.

LaunchAtLoginController *launchController = [[LaunchAtLoginController alloc] init];
[launchController setLaunchAtLogin:YES];
[launchController release];

IMPLEMENTATION (Interface builder):

  • Open Interface Builder
  • Place a NSObject (the blue box) into the nib window
  • From the Inspector - Identity Tab (Cmd+6) set the Class to LaunchAtLoginController
  • Place a Checkbox on your Window/View
  • From the Inspector - Bindings Tab (Cmd+4) unroll the > Value item
    • Bind to Launch at Login Controller
    • Model Key Path: launchAtLogin

IS IT WORKING:

After implementing either through code or through IB, setLaunchAtLogin:YES and then check System Preferences > Accounts > Login Items. You should see your app in the list of apps that will start when the user logs in.

CAVEATS (HelperApp Bundles):

If you're trying to set a different bundle (perhaps a HelperApp as a resource to your main bundle) you will simply want to change - (NSURL *)appURL to return the path to this other bundle.

REQUIREMENTS:

Works on 10.6/10.5
