如何将TableView连接到DetailView [英] How do I connect my TableView to a DetailView

问题描述

我的问题是，当用户按下田纳西州啤酒花时，当他们按下我想要推送到列出该区域规格的详细视图时......所以从应用程序的开头它将去田纳西州（RootTable） - >田纳西州啤酒花（SecondTable） - >规格（的DetailView）。有人能指导我如何使其正常运作吗？



谢谢！



RootTableViewController.h

My question is ay when the user presses "Tennessee Hops", when they press that I want to it to push to a detail view listing the specs of that area... So from the opening of the app it would go Tennessee(RootTable) -> Tennessee Hops(SecondTable) -> Specs(DetailView). Can someone lead me in the right direction as to how to get this to function correctly?

Thanks!
