iphone/ipad triggering unexpected resize events

Store the window width and check that it has actually changed before proceeding with your $(window).resize function:

jQuery(document).ready(function($) {

    // Store the window width
    var windowWidth = $(window).width();

    // Resize Event

        // Check window width has actually changed and it's not just iOS triggering a resize event on scroll
        if ($(window).width() != windowWidth) {

            // Update the window width for next time
            windowWidth = $(window).width();

            // Do stuff here


        // Otherwise do nothing
