iOS 10未检测到Touchend事件

所以这个代码示例适用于iOS 8和9上的10.3 iphone 6和11上的其他iPhone的iPad。严格来说似乎是iOS 10的问题。我有一个脚本来检测滑动方向,如果向上滑动一个div向上或向下滑动。

在iOS 10中,如果我在屏幕的上半部分开始向上滑动它可以工作,如果我从屏幕的一半以下开始它将无法工作,并且滑动方向将注册为“没有”#39;你可以在这个全屏代码中看到它

// The inner-most qualifiers can be put before them though without introducing ambiguity
