在视图控制器之间进行通信 [英] Communicating between view Controllers

问题描述

我的一个视图控制器具有多个UISwitch，并且我希望另一个视图控制器能够访问If/and语句的UISwitch的值.如何在Objective-c中执行此操作?

one of my view controllers has several UISwitches, and I want another view Controller to be able to access the values of the UISwitches for If/and statements. How do I do this in Objective-c?

推荐答案

您可能不想这样做.如果您希望第二个ViewController基于第一个ViewController的开关而具有不同的行为，则应仅将这些开关绑定到User Defaults，您可以在应用程序中的任何位置读取它.

You probably don't want to do that. If you want a second ViewController to have different behavior based on switches thrown in the first, you should just bind the switches to User Defaults, which you can read anywhere in your app.
