推荐答案

拆分视图将该消息发送给其委托，询问代理是否应隐藏该分隔符。因此，是代表，并回答拆分视图的问题。

The split view sends that message to its delegate, to ask the delegate whether it should hide that divider. So, be the delegate, and answer the split view's question.

请务必查看文档。这可能是那个消息不会实现你想要的。该文档列出了您可以通过回复该邮件所做的一切。

Be sure to check out the documentation. It's possible that that message won't accomplish what you want it to. The documentation lists everything you can do by responding to that message.
