ios - 委托(delegate)按钮单击在 tableview 单元格中不起作用

Question

我正在使用 Delegate 方法来访问我的表格 View 的单元格的按钮单击方法信息。我的表格 View 单元格是自定义的。我在单独的 xib 文件中设计了单元格，还为单元格声明了一个 tableViewCell 类型类。并将该类赋予我设计的单元格。我在同一表格 View 中根据日期和其他一些条件加载不同的单元格设计。但问题是当我点击我的单元格内的按钮时，它不起作用。我已经在代码所在的地方下了断点，但是就是不去断点。

这是我遵循的步骤。当我使用 storyboards 在原型(prototype)单元格内设计我的表格单元格时，它运行良好。我使用 xib 做了同样的事情，但我不知道哪里出了问题。

这是我自定义的单元格的 .h 类，我声明了委托(delegate) #导入

@class CellForComingDates;

@protocol ComingDateRowDelegate <NSObject>

-(void)DeleteButtonAction_new:(CellForComingDates*)cell;


@end


@interface CellForComingDates : UITableViewCell

@property (strong, nonatomic) IBOutlet UIImageView *cellImage;
@property (strong, nonatomic) IBOutlet UILabel *personName;
@property (strong, nonatomic) IBOutlet UILabel *appoinmentTime;
@property (strong, nonatomic) IBOutlet UILabel *appoinmentDate;
@property (strong,nonatomic) NSString* appoinmentstartTime;
@property (strong,nonatomic) NSString* appoinmentendTime;
@property (strong,nonatomic) NSString* appoinmentID;
@property (strong,nonatomic) NSString* USER;

@property (weak) id<ComingDateRowDelegate> comingDateDel;


@end

这是包含我的 IBAction 方法的 .m 类。 并且我已将 IBaction 正确连接到按钮

- (IBAction)DeleteButton:(id)sender {
[self.comingDateDel DeleteButtonAction_new:self];
}

然后，在 tableView 类中，我实现了点击方法

-(void)DeleteButtonAction_new:(CellForComingDates*)cell{
     AppoinmentID = cell.appoinmentID;
   UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Delete Appoinment"
                                                message:@"click ok to delete"
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:@"Cancel",nil];
alert.tag = kAlertViewTwo;
[alert show];
}

但是当我点击按钮时它没有响应...有人能告诉我这里发生了什么吗？

谢谢

Answer 1

我想你忘记了[cell setComingDateDel:self];

在 cellForRowAtIndexPath 中添加此调用。

更新:

尝试在执行 return 之前添加 [cell setComingDateDel:self];。
