HTML5 mobile boilerplate建议添加此Javascript片段以修复“iPhone视口缩放错误”:

// Fix for iPhone viewport scale bug 
// http://www.blog.highub.com/mobile-2/a-fix-for-iphone-viewport-scale-bug/

MBP.viewportmeta = document.querySelector && document.querySelector('meta[name="viewport"]');
MBP.ua = navigator.userAgent;

MBP.scaleFix = function () {
  if (MBP.viewportmeta && /iPhone|iPad|iPod/.test(MBP.ua) && !/Opera Mini/.test(MBP.ua)) {
    MBP.viewportmeta.content = "width=device-width, minimum-scale=1.0, maximum-scale=1.0";
    document.addEventListener("gesturestart", MBP.gestureStart, false);
  }
};
MBP.gestureStart = function () {
    MBP.viewportmeta.content = "width=device-width, minimum-scale=0.25, maximum-scale=1.6";
};

使用iPhone查看此demo page。将手机从纵向旋转到横向。请注意页面在横向视图中放大。
