Question

我在自定义单元格中有四个按钮，例如ans1，ans2，ans3，ans4，我想验证每个didselectrowatindexpath indexpath.row中的按钮我该怎么做？我还设置了按钮标签（1,2,3,4）？这是我的cellforatindexpath代码

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *cellId = @"Cell";
    ContestQATableViewCell *cell =(ContestQATableViewCell *)[tableViewQA dequeueReusableCellWithIdentifier:cellId];
    if (cell==nil)
    {
        NSArray *myNib;
        myNib =[[NSBundle mainBundle]loadNibNamed:@"ContestQATableViewCell" owner:self options:nil];
        cell = (ContestQATableViewCell *)[myNib lastObject];
    }
    cell.question.text = [getContestQArray objectAtIndex:indexPath.row];
    NSString *str1 = [getAnswer1Array objectAtIndex:indexPath.row];
    NSString *str2 = [getAnswer2Array objectAtIndex:indexPath.row];
    NSString *str3 = [getAnswer3Array objectAtIndex:indexPath.row];
    NSString *str4 = [getAnswer4Array objectAtIndex:indexPath.row];
    [cell.answer1 setTitle:str1 forState:UIControlStateNormal];
    [cell.answer2 setTitle:str2 forState:UIControlStateNormal];
    [cell.answer3 setTitle:str3 forState:UIControlStateNormal];
    [cell.answer4 setTitle:str4 forState:UIControlStateNormal];
    return cell;
}

如果我点击ans1剩下的3个按钮将被取消选择如果我点击ans2剩下3个按钮将取消选择等等... 在每个自定义单元格中

- (IBAction)select:(id)sender {

    UIButton* btn=(UIButton*)sender;

    CustomCell* cel=(CustomCell*)[btn.superview superview];

    if (cel.a1.tag==btn.tag) {

        [cel.a1 setImage:[UIImage imageNamed:@"active.png"] forState:UIControlStateNormal];
    }else{

        [cel.a1 setImage:[UIImage imageNamed:@"inactive.png"] forState:UIControlStateNormal];
    }
    if (cel.a2.tag==btn.tag) {

        [cel.a2 setImage:[UIImage imageNamed:@"active.png"] forState:UIControlStateNormal];
    }else{

        [cel.a2 setImage:[UIImage imageNamed:@"inactive.png"] forState:UIControlStateNormal];
    }
    if (cel.a3.tag==btn.tag) {

        [cel.a3 setImage:[UIImage imageNamed:@"active.png"] forState:UIControlStateNormal];
    }else{

        [cel.a3 setImage:[UIImage imageNamed:@"inactive.png"] forState:UIControlStateNormal];
    }
    if (cel.a4.tag==btn.tag) {

        [cel.a4 setImage:[UIImage imageNamed:@"active.png"] forState:UIControlStateNormal];
    }else{

        [cel.a4 setImage:[UIImage imageNamed:@"inactive.png"] forState:UIControlStateNormal];
    }

}

我看到你的工具现在不好。有办法得到它，但目前尚不清楚。所以我建议你应该将按钮操作的动作放到ContestQATableViewCell的类中，并调用委托给控制器的表视图和doSomeThingWithit

首先创建委托：

@protocol ContestCellDelegate <NSObject>

@required
- (void)didTapButtonAtIndexpath:(NSIndexPath *)indexPath posision:  (NSInteger)position;
@end
  @interface ContestQATableViewCell : UITableViewCell

 @property (weak, nonatomic) IBOutlet UILabel *question;
 @property (weak, nonatomic) IBOutlet UIButton *answer1;
 @property (weak, nonatomic) IBOutlet UIButton *answer2;
 @property (weak, nonatomic) IBOutlet UIButton *answer3;
 @property (weak, nonatomic) IBOutlet UIButton *answer4;

 @property (strong, nonatomic) NSIndexPath *indexPath;
 @property (weak, nonatomic) id<ContestCellDelegate>delegate;

 //- (void)configCellWithQuestion:()


  @end

当你点击它时，你在Cell中添加动作，你调用delgate：

 - (IBAction)answer1IsTapped:(id)sender {
if (self.delegate) {
    [self.delegate didTapButtonAtIndexpath:self.indexPath posision:1];
   }
}
 - (IBAction)answer2IsTapped:(id)sender {
if (self.delegate) {
    [self.delegate didTapButtonAtIndexpath:self.indexPath posision:2];
}
}

   - (IBAction)answer3IsTapped:(id)sender {
if (self.delegate) {
    [self.delegate didTapButtonAtIndexpath:self.indexPath posision:3];
}
}

   - (IBAction)answer4IsTapped:(id)sender {
if (self.delegate) {
    [self.delegate didTapButtonAtIndexpath:self.indexPath posision:4];
}
 }

在控制器中你抓住并做你想做的事情：

    - (void)didTapButtonAtIndexpath:(NSIndexPath *)indexPath posision:(NSInteger)position {
//You can get index postion and do anything here
NSLog(@"%ld %ld", (long)indexPath.row, (long)position);
}
