I've seen a few answers for this but it still wasn't entirely clear without an example. The docs say:

The resolve keys MUST be injected into the child states if you want to wait for the promises to be resolved before instantiating the children.

Here's the example:

    $stateProvider.state('parent', {
          resolve:{
             resA:  function(){
                return {'value': 'A'};
             }
          },
          controller: 'parentCtrl'
       })
       .state('parent.child', {
          resolve:{
             // Adding resA as an argument here makes it so that this child state's resB resolve
             // function is not run until the parent state's resA resolve function is completed.
             resB: function(resA){
                return {'value': resA.value + 'B'};
             }
          }
          controller: 'childCtrl'
        })

And you don't have to inject resA into the child controller.

Answer 2

If you add auth to the dependency injection of your grandchild resolve, ui-router will resolve it prior to the grandchild resolve.

['authsrv', 'auth', function(authsrv, auth){}]

Hope that makes sense.
