I am trying to use TMS in Leaflet to visualize some existing data that already exists in any GeoServer. So this is my code and still does not work. So the question is:
How could I show the following TMS in Leaflet?

             <html>
      <head>
        <title>A Leaflet map!</title>
        <link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css"/>
        <script src="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.js">      </script>
        <style>
          #map{ height: 100% }
        </style>
      </head>
      <body>

        <div id="map"></div>

        <script>

        // initialize the map
        var map = L.map('map').setView([-104.0625,44.296875], 9);

        // base maps
        var       county=L.tileLayer('http://localhost:9090/geoserver/gwc/service/tms/1.0.0/sf%3Aroads@EPSG%3A4326@png/{z}/{x}/{-y}.png').addTo(map);

        </script>
      </body>
      </html>

From TMS server 


      <TileMap title="Spearfish roads" srs="EPSG:4326" profile="global-geodetic" href="http://localhost:9090/geoserver/gwc/service/tms/1.0.0/sf%3Aroads@EPSG%3A4326@png"/>

      </TileSets>

I have also tried this

           var county=L.tileLayer('http://localhost:9090/geoserver/gwc/service/tms/1.0.0/sf%3Aroads@EPSG%3A4326@png/{z}/{x}/{y}.png', { tms: true }).addTo(map);

Just a gray map!
