code: function tapLinksAndImages() {
          editor.on('click', function (e) {
            var elm = e.target;
  
            do {
              if (elm.tagName === 'A') {
                e.preventDefault();
                return;
              }
            } while ((elm = elm.parentNode));
          });
  
          editor.contentStyles.push('.mce-content-body {-webkit-touch-callout: none}');
        }
docs: iOS 7.1 introduced two new bugs:
  1) It's possible to open links within a contentEditable area by clicking on them.
  2) If you hold down the finger it will display the link/image touch callout menu.
