Question

我有一个带滑块和标签的自定义表格视图单元格。我在自定义单元格上为滑块和标签创建了一个属性。我想将滑块值传输到标签。这就是我的束缚：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSDictionary *cellInfo = [[self.sections objectAtIndex:currentTab] objectAtIndex:indexPath.row];
    HLMagnitudoTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[cellInfo objectForKey:@"cell"] forIndexPath:indexPath];

    UIImageView *radioIndicator = (UIImageView *)[cell.contentView viewWithTag:200];

    radioIndicator.image = (currentBullet != indexPath.row) ? [UIImage imageNamed:@"RadioOff"] : [UIImage imageNamed:@"RadioOn"];

    UIImageView *av = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 80)];
    av.backgroundColor = [UIColor clearColor];
    av.opaque = NO;
    av.image = [UIImage imageNamed:@"NewsSeparetor.png"];
    cell.backgroundView = av;

    cell.slider.maximumValue = 100;
    cell.slider.minimumValue = 1;
    cell.slider.continuous = TRUE;
    cell.slider.tag = 1;
    cell.slider.value = [cell.label.text intValue];
    [cell.slider addTarget:self action:@selector(sliderChanged:) forControlEvents:UIControlEventValueChanged];
    return cell;
}

- (void)sliderChanged:(UISlider *)slider
{

}

在单元格中创建滑块并为每个滑块设置标记值：例如：

slider.tag=1

注册更新值时要调用的方法：

[slider addTarget:self action:@selector(sliderChanged:) forControlEvents:UIControlEventValueChanged];

然后在您的方法中，您将能够使用标记获取滑块的值：

-(void)sliderChanged:(UISlider *)sender {
    int tag = sender.tag; 

    if (tag ==1 ) //Update the label
       slider1Label.text=[NSString strinWithFormat:@"%d",sender.value]
    }
   else if (tag == 2){
   //Do something else
   }
}
