所以问题是我没有编写此代码，而只是尝试编辑一些代码。它是与某个电气I / O板有关的代码，该I / O板是工厂系统的输入/输出控制板，由各种iOS设备运行。
我似乎无法弄清楚以前的编码器在此类中的操作：

我遇到的问题是我无法弄清楚如何在情节提要上的UIProgressViews中取值（如您所说，这是一个琐碎的概念）。但是，通过这种设置它相当复杂。
第二个问题是；我不确定是否可以调试此方法，因为该应用程序仅在将外部设备（nanospark控制器板）连接到iPod时运行。
我遇到的最后一个但也是最后一个问题是，我假设正在调用IBAction InputChannelChanged（无法使用上述断点定期调试此操作，因为它需要外部设备来运行该应用程序），但是当我运行该应用程序时，它会执行所有操作它应该和按钮正确响应原始软件开发人员已编码的内容。
这意味着，如果我将发短信方法添加到IBAction中（通过添加[appDelegate watchPins @“ TEST”]），它不会将文本发送给用户，但是按钮仍会按照先前的操作进行操作开发人员的愿望...。这意味着确实调用了IBAction方法...但是，为什么我的文本没有通过？我知道[appDelegate watchPins：@“ TEST”];应该像我在他的其他几个班级中使用过的那样工作。
这是显示AnalogVC.m UI的屏幕截图：
http://i.stack.imgur.com/NNpZk.png
不必强制回答所有这些问题，只是我觉得有必要提供所有这三个问题，以解决问题的更多背景信息。感谢您，并为TL; DR感到抱歉。
我会上传图片，但是我没有要求的最低信誉。
我试图添加另一个IBAction只是为了查看按钮是否对此做出反应；即使我从其他工作类中复制了准确的代码，也还是一无所有。
最佳答案
通常的规则是在IB（界面生成器）中检查您的插座和操作。通常，这是一个断开的链接。
如果不是那样，您将需要找出一种调试方法。如果原始开发人员无法模拟专用硬件，他们是如何编写该应用程序的？
您的SO读者无法知道导致该应用无法正常运行的原因。
一种选择是将日志语句添加到IBAction方法中，运行开发以在现场构建程序，然后将iPad连接到Xcode并查看控制台日志以查看日志语句的输出。
顺便说一句，您发布了数百行代码，其中很多是Xcode添加的样板代码，其余大部分与您要解决的问题无关。最好减少发布到相关部分的代码，以使读者可以了解重要内容。否则，他们可能会在滚动无关代码的堆中试图找到与您的帖子相关的内容时失去耐心。
