iOS devices kill JS execution the second you switch away, this function detects when the JS execution continues and automatically reconnects with socket.io

ios.reconnect.js

var browsers = {
  isiOS: function() {
    return ( navigator.userAgent.indexOf( 'iPad' ) > -1
        || navigator.userAgent.indexOf( 'iPhone' ) > -1
        || navigator.userAgent.indexOf( 'iPod' )   > -1 );
  }
};

// Moving away from this tab..
if( browsers.isiOS() ) {
  // Check if someone is switching tabs!
  var Time    = new Date().getTime()
    , getTime = function( intTime ) {
      var timeOut = setTimeout( function() {
        getTime( Time );
      }, 500 );

      var intNow = new Date().getTime();
      if( ( intNow - intTime ) > 1000 ) {
        if( false === socket.connection.socket.connected )
          socket.connection.socket.connect();
      }
      clearTimeout( timeOut );

      Time = new Date().getTime();
      var timeOut = setTimeout( function() {
        getTime( Time );
      }, 500 );
  };
  getTime( Time );
}
