编辑:我向 Apple 报告了这个错误，现在它已关闭，在测试版 iOS 9.0 (13A4254v) 上进行了测试并且可以正常工作。

为了更好的解释而编辑:

我在一个网页中有一堆文章，都包裹在一个 div(列)中。这些文章有一个具有绝对位置和固定宽度和高度的类。

有一个应用按钮:- 包装器/列的 translate3d- 一个 window.history.pushState

所有样式都正确应用于所有文章，但是当我按下按钮并在 pushState 之后，所有/某些第 nth-child() 样式未正确应用(左、上和宽度)。如果我将 :nth-child() 更改为 :nth-of-type()，则在 pushState 之后一切正常。

当 safari 在按下点击按钮并影响 translate3d 元素(硬件加速)后确定激活切换到阅读器模式的可能性时，问题似乎是可见的。

它发生在使用 iPad2、iPad3 retina 和 4 的 Safari iOS8 上。它不会发生在使用 iPad mini retina 的情况下。使用 iOS7 和之前的版本都可以正常工作，但使用 iOS8 就不行。

你有过这样的经历吗？

最佳答案

事实上 nth-child 在 IOS8 上不工作。

切换为 nth-of-type 对我有用。

很好的支持https://developer.mozilla.org/en-US/docs/Web/CSS/:nth-of-type

也就是说，如果您不想冒险，可以按如下方式检测 IOS 8。 

function isIOS8() {
  if ("600.1.4" == $.browser.version || ~navigator.userAgent.indexOf('OS 8_') ){
    return true;
  }
  return false;
}

var i=0,
    $el = $('ul.poll');

if( isIOS8() ){
    $el.find(' li:nth-of-type(' + (i + 1) + ')').text('my first Child');
}else{
    $el.find('.choice:nth-child(' + (i + 1) + ')').text('my first Child');
}
