How to use a pop-up at the beginning of the ionic application?

I'm sorry for my bad english.

Still new to Ionic I create a simple application.

I would like to start the application with a pop-up but I don't know how to do it.

When you start a new application with Ionic, you can see at the end of app.js

"$urlRouterProvider.otherwise('/app/accueil');"

This is to begin the application on the page accueil, but I want to start with "login()" for exemple.

Someone can help me?

Thanks

I have used Ionic app and created a login page with angular router. Check my git code. https://github.com/gopinathshiva/ionic-chat-app/blob/master/www/js/app.js . Hope this helps

I have find a solution.

I solved my problem with this : http://codepen.io/calendee/pen/oCLJF

.factory('AuthService', function($rootScope) {

var loggedIn=false;

return {

checkLogin : function() {
  $rootScope.$broadcast('loggedIn', { 'loggedIn' : loggedIn });
  return loggedIn;

},

login : function() {
  loggedIn = true;
  $rootScope.$broadcast('loggedIn', { 'loggedIn' : loggedIn });
}  

}

})

Thanks for your attention and help!
