New description:

 `wp_schedule_event` will not accept array() for the hook (must be string).
 As such, `wp_schedule_event( time(), 'daily', array($this,'hook') );` will
 not work, however, moving the hook method outside of the class will work
 as the `$hook` is no longer an array.

Comment:

 You are mixing up "hook" and "callback" here.
 `wp_schedule_event` indeed requires a string as the "hook", in the sense
 of plugin action hook. You can then attach a "callback" (usually a
 function or class method) to that action hook:
 {{{
 wp_schedule_event( time(), 'daily', 'my_unique_plugin_event_hook' );
 add_action( 'my_unique_plugin_event_hook', array( $this,'hook' ) );
 }}}
