Adds a fieldset to theme settings form which allows site administrators to specify Apple Touch icons for Drupal websites. The Touch icon settings behave in a similar manner to the Site Logo and Favicon settings provided by Drupal core.

Code

function _touch_icons_create_touch_icon_url($key, $precomp = FALSE) {
  $themes = list_themes();
  $theme_object = $themes[$key];
  $settings = theme_get_settings($key);
  $icon_type = $precomp ? 'precomp' : 'plain';
  $default_filename = 'apple-touch-icon' . ($precomp ? '-precomposed' : '') . '.png';

  // build apple-touch-icon URL
  $url = '';
  if (!empty($settings['toggle_touch_icon_' . $icon_type])) {
    if (!empty($settings['default_touch_icon_' . $icon_type])) {
      if (file_exists($touch_icon = dirname($theme_object->filename) . '/' . $default_filename)) {
        $url = base_path() . $touch_icon;
      }
      else {
        $url = base_path() . drupal_get_path('module', 'touch_icons') . '/' . $default_filename;
      }
    }
    elseif ($settings['touch_icon_' . $icon_type . '_path']) {
      $url = base_path() . $settings['touch_icon_' . $icon_type . '_path'];
