Is there a way to make $ionicLoading display with just an animated icon (e.g. - spinning wheel). I can sorta make it work by adding a html content to show the icon. But, it still displays the box around it.
What version of Ionic are you using?

Andy did some neat stuff with that.
I waited till beta 1 was released before I commented. But, the same behavior exists. You can see what I’m trying to do here:
Notice the black box around the icon. If there’s no text, I would rather it display just the icon without the box. Ideally, it would be nice if I could just specify the name of the icon or its corresponding class name.
I re-opened an issue that was supposed to solve it.  The problem is that the .loading class effectively it’s own backdrop.
I was redirected here form an ionicforum post where I can’t see the text but only the ionic loading icon. But i don’t seem to find right solution.
For me, backdrop is working fine. but not seeing my message ‘fetching images’ though I give content as ’ Fetching images’
Following is my code
$scope.show = function(message){
      $scope.loading = $ionicLoading.show({
          content: '<i class="ion-loading-c"></i> '+ message,
          animation: 'fade-in',
          noBackdrop: false,
          maxWidth: 200,
          showDelay: 500
      });
  }
I see only that small loading icon with dimmed screen but not my message 
I’m not sure which release of Ionic you are using (nightly or Beta 13).  However, I don’t think content is an option for the loading indicator in either case.  Perhaps you wanted template ?
For the latest ionic version this works for me:
$ionicLoading.show({
  template: '<ion-spinner></ion-spinner>'+
            '<p>Login ...</p>'
});
