【问题描述】：

我添加了一个自定义单元格，如下所示用于步进进度。 UI 透视图，它看起来是我想要的，但我无法弄清楚如何确定按钮是否已被点击。

我的灵感来自https://github.com/yenbekbay/AYStepperView，但是这个有 PageViewController，我无法将它添加到 tableCell 中。

#import "StepperProgressTableViewCell.h"
#import "AYStepperView.h"

static CGFloat const kFormStepperViewHeight = 80;

@interface StepperProgressTableViewCell ()

@property (nonatomic) AYStepperView *stepperView;
@property (nonatomic) NSUInteger currentIndex;
@property (nonatomic) NSUInteger currentStep;

@end

@implementation StepperProgressTableViewCell

- (void)awakeFromNib 
    [super awakeFromNib];
    // Initialization code
    [self setUpViews];
    self.currentIndex = 0;
    self.currentStep = 0;


- (void)setSelected:(BOOL)selected animated:(BOOL)animated 
    [super setSelected:selected animated:animated];


#pragma mark Private

- (void)setUpViews 

    self.stepperView = [[AYStepperView alloc]initWithFrame:CGRectMake(0, 40 , self.frame.size.width, kFormStepperViewHeight) 
                         titles:@[NSLocalizedString(@"Start", nil), 
                                 NSLocalizedString(@"Cooking", nil), 
                                 NSLocalizedString(@"Ready", nil)]];
    self.stepperView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;
    self.stepperView.userInteractionEnabled = YES;
    [self addSubview:self.stepperView];

【问题讨论】：

请不要发布您的整个代码，而只发布与您的问题相关的部分。

【参考方案1】：

如果您想从单元格捕获事件到视图控制器，最简单的方法是创建一个协议并将视图控制器设置为单元格的委托。我相信这里有很多类似的问题可以帮助你喜欢this one。
