iOS9.1终于可以关闭讨厌的300ms延迟了

通过viewprot配置来关闭,FastClick快要完成历史使命了。

Fast-Tap on iOS

On Safari for iOS, the 350 ms wait time to detect a second tap has been removed to create a “fast-tap” response. This is enabled for pages that declare a viewport with either width=device-width or user-scalable=no. Authors can also opt in to fast-tap behavior on specific elements by using the CSS touch-action property, using the manipulation value.

See http://www.w3.org/TR/pointerevents/#the-touch-action-css-property.
