ios - 组件的 "row container"是什么？

Question

https://facebook.github.io/react-native/docs/listview.html说:

removeClippedSubviews bool

A performance optimization for improving scroll perf of large lists, used in conjunction with overflow: 'hidden' on the row containers.

和 https://facebook.github.io/react-native/docs/performance.html说:

removeClippedSubviews

"When true, offscreen child views (whose overflow value is hidden) are removed from their native backing superview when offscreen. This can improve scrolling performance on long lists. The default value is true."(The default value is false before version 0.14-rc).

This is an extremely important optimization to apply on large ListViews. On Android the overflow value is always hidden so you don't need to worry about setting it, but on iOS you need to be sure to set overflow: hidden on row containers.

但什么是“行容器”？

<ListView renderRow={(r) => <Row r=r>}>

我需要申请这个 overflow: hidden到 <ListView>或 <Row>风格？

从您共享的文档中-

When true, offscreen child views (whose overflow value is hidden) are removed from their native backing superview when offscreen.

这意味着在您的情况下，您需要申请 overflow: hidden到 Row您在 renderRow 中使用过的组件.
