【问题描述】：
所以问题是我没有编写代码，只是尝试编辑一些代码。它是属于某个电气 I/O 板的代码，它是工厂系统的输入/输出控制板，由各种 iOS 设备运行。
我似乎不太明白以前的编码员在这个课程中做了什么：
//
// AnalogVC.m
//
#import "AnalogVC.h"
#import "AppDelegate.h"
@interface InputItem : NSObject
@property (weak,nonatomic) UISwitch *onSwitch;
@property (weak,nonatomic) UIProgressView *progressView;
@property (weak,nonatomic) UILabel *valueLabel;
@end
@implementation InputItem
AppDelegate *appDelegate;
+ (id)itemWithSwitch:(id)temp progress:(id)progress label:(id)label
{
InputItem *item = [[InputItem alloc] init];
item.onSwitch = temp;
item.progressView = progress;
item.valueLabel = label;
return item;
}
- (void)setDisconnected
{
self.onSwitch.on = NO;
self.onSwitch.enabled = NO;
self.valueLabel.text = @"0.000 v";
self.progressView.progress = 0;
}
- (void)setOn
{
self.onSwitch.on = YES;
self.onSwitch.enabled = YES;
self.valueLabel.text = @"0.000 v";
self.progressView.progress = 0;
[appDelegate watchPins:@"testing ON"];
}
- (void)setOff
{
self.onSwitch.on = NO;
self.onSwitch.enabled = YES;
self.valueLabel.text = @"0.000 v";
self.progressView.progress = 0;
[appDelegate watchPins:@"testing OFF"];
}
- (void)setValue:(double)value
{
if (self.onSwitch.on)
{
self.valueLabel.text = [NSString stringWithFormat:@"%0.3f v",value];
self.progressView.progress = value/5.0;
if(value > 0.8){
[appDelegate watchPins:@"testing VALUE"];
}
}
}

我遇到的问题是我无法弄清楚如何从情节提要上的 UIProgressViews 获取值（就像你说的那样，这是一个微不足道的概念）。然而，这种设置是相当复杂的。
第二个问题是；我不确定是否有办法调试它，因为应用程序仅在外部设备（nanospark 控制器板）连接到 iPod 时运行。
我遇到的最后一个也是最后一个问题是我假设正在调用 IBAction InputChannelChanged（不能使用上述断点定期调试它，因为它需要外部设备来运行应用程序），但是当我运行应用程序时它做了它应该做的一切，并且按钮对原始软件开发人员的编码做出正确的反应。
这意味着，如果我将我的发短信方法添加到 IBAction（通过添加 [appDelegate watchPins@"TEST"]），它不会将文本发送给用户，但按钮仍然会执行它们应该按照一致性执行的操作对以前的开发人员的愿望....这意味着确实正在调用 IBAction 方法...但是为什么我的文本没有通过呢？我知道 [appDelegate watchPins:@"TEST"];应该像我在他的其他几个课程中使用过的那样工作。
这是显示 AnalogVC.m 的 UI 的屏幕截图：

不必回答所有这些问题，只是我觉得有必要提供所有三个问题以更好地了解问题的背景。感谢和抱歉 TL;DR。
我会上传图片，但我没有所需的最低声望。
我尝试添加另一个 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确切的代码，仍然一无所获。
