这对我来说很难解释，但我会尝试：
首先，我的网页在 iOS6.x、Android、W7 中的 mobilebrowser 以及桌面浏览器 IE9、Safari 和 Chrome 上运行。该问题发生在iOS7中的苹果移动Safari浏览器中。我遇到了粘性页脚和虚拟键盘的问题，但已经解决了here https://stackoverflow.com/questions/18977540/div-element-wont-stay-at-the-bottom-when-ios-7-virtual-keyboard-is-present
现在我在页面上滚动时遇到问题。 iOS7上向下滚动时，通常导航栏会隐藏，地址栏会缩小。这不会发生。固定页眉和页脚之间的内容是滚动的，但内容的底部被页脚和导航栏重叠。我必须等待滚动停止才能再次向下滚动。然后地址栏将缩小，导航栏将隐藏，底部内容将显示。当我在页面底部并想要向上滚动时，会发生同样的事情，只是向上：滚动到顶部，标题和小地址栏与上部内容重叠，等待滚动停止，然后再次滚动以展开地址栏、显示导航栏以及显示上部内容。
希望这张图片可以帮助：
