什么是“iPhone 视口比例错误”？
HTML5 移动样板 建议添加这段 Javascript 来修复“iPhone 视口比例错误”：
// 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";
};

HTML5 mobile boilerplate recommends adding this snippet of Javascript to fix the "iPhone viewport scale bug":

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 查看此演示页面。将手机从纵向旋转为横向。请注意，页面在横向视图上按比例放大。
请参阅此处了解详细信息 http://webdesignerwall.com/tutorials/iphone- safari-viewport-scaling-bug
