问题描述

我有一个问题，我可以使用视图中可浏览到uitableview的普通按钮，从单元格获取值并设置文本标签(在第一个视图中)的方式这个值，然后使用后退按钮返回到第一个视图?

最简单的方法是将单元格中的值捕获到全局变量中(您可以在App Delegate或Singleton中设置全局变量)，而所有按钮要做的就是抓住该变量的值，而不是进入UITableView来获取某个单元格值.

Easiest way is to just have the value in the cell be captured in a global varialble (you can set up global variables either in the App Delegate or in a Singleton) and that way all the button has to do is grab that variable's value instead of going into the UITableView to get a certain cell value.
