When a parent view has multiple peer views, iOS will select the highest level View to respond to the event, and the underlying view event will never be responded.
-Weex add attribute `eventPenetrationEnabled` to `<div>` component. When the value is `true`, the view's children views still respond to the event normally, while the view itself will not respond to the event, but pass the event to the lower level View.

当一个父View存在多个同级子View时，由于`iOS`会选择层级最高的View来响应事件，底层的View的事件永远都不会响应。
-Weex在`<div>`组件中增加了`eventPenetrationEnabled`属性，当值为`true`时，View的子View仍能正常响应事件，但View自身将不会响应事件，而是将事件向下层View传递。
