Focus is ignored by iOS devices because of the timeout we use to defer the event broadcast to the next tick. I have a partial solution and will send a pull request.

Hi,
I want to focus on an input each time I open a modal, so I injected your service into the modal's controller, but it doesn't focus on the input unless I wrap the focus() call inside some timeout function :

// What I do
function LoginModalCtrl ($scope, $modalInstance, focus, $timeout) {
        $timeout(function() {
            focus('userCode');
        }, 0);
    };

// What I want
function LoginModalCtrl ($scope, $modalInstance, focus) {
            focus('userCode');
    };

Is there a way to achieve the second one ? :)

When used in an ng-repeat loop, I only wanted it to trigger focus on first item, so I did something like this:

<a ... focus-on="{{$first ? 'focus-just-on-me' : '' }}>...</a>

However, that made it add listeners even for when focus-on was not defined.

PR at #10 if interested.

Can we add support for loading the ngFocusOn as a CommonJS module?

See example of Angular UI-Router:
https://github.com/angular-ui/ui-router/blob/master/release/angular-ui-router.js

This will allow doing:

var ngFocusOn = require('ng-focus-on');

angular.module('admin', [
    ngFocusOn
])

Instead of hard coding the module name.
