How can a Cocoa application add itself as a global login item?

Question

I tried

LSSharedFileListRef globalLoginItems = LSSharedFileListCreate(NULL, kLSSharedFileListGlobalLoginItems, NULL);
if (globalLoginItems) {
    LSSharedFileLi         


        

Answer 1

I got this working. All I had to do was add these lines before I insert the app into the login items:

AuthorizationRef auth = NULL; 
AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &auth);
LSSharedFileListSetAuthorization(globalLoginItems, auth);

The docs for LSSharedFileListSetAuthorization say that we have to get the right system.global-login-items for this, but it worked nevertheless!

But this will fail if the user is not an administrator. For it to work then too, you'll have to do this:

AuthorizationItem right[1] = {{"system.global-login-items.", 0, NULL, 0}};
AuthorizationRights setOfRights = {1, right};
AuthorizationRef auth = NULL; 
AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &auth);


AuthorizationCopyRights(auth, &setOfRights, kAuthorizationEmptyEnvironment,
                              (kAuthorizationFlagDefaults
                               | kAuthorizationFlagInteractionAllowed
                               | kAuthorizationFlagExtendRights), NULL);

It's also advisable to refer to the docs for details.
