滚动后 iOS UITableViewCell 无法正确更新

Question

这就是我所拥有的:我有一个带有自定义 UITableViewCell 的 TableView，它正在从 MutableArray 加载数据。

在我的 cellForRow: 我调用代码用数组中的数据绘制 subview ，当我向下滚动和向上滚动时，该 subview 看起来非常错误，但每个标签似乎都是正确的...

我在谷歌上尝试了很多答案，但都没有解决它，我什至将 subview 放到数组中，但也不起作用，抱歉，我还不能发布图片:(

NSMutableArray *mintHistoryList = //Array of Epin objects 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];
// Configure the cell...

EPinObject *data;

if (indexPath.row < self.mintHistoryList.count && [[self.mintHistoryList objectAtIndex:indexPath.row] isKindOfClass:[EPinObject class]])
    {
        data = [self.mintHistoryList objectAtIndex:indexPath.row];
        UILabel *pinGeneratedDateLabel = (UILabel *)[cell viewWithTag:100];
        pinGeneratedDateLabel.text = data.pinGeneratedTime;

        UILabel *pinNumberLabel = (UILabel *)[cell viewWithTag:101];
        pinNumberLabel.text = data.pinCode;

        UILabel *pinOriginalLabel = (UILabel *)[cell viewWithTag:102];
        pinOriginalLabel.text = [NSString stringWithFormat:@"%@%@", [Common currencyFloatRemake:data.pinOriginalAmount],[Common currencyCodeToSymbol:data.pinCurrencyCode]];
        pinOriginalLabel.adjustsFontSizeToFitWidth=YES;
        pinOriginalLabel.minimumScaleFactor=0.5;

        UILabel *pinLeftLabel = (UILabel *)[cell viewWithTag:103];
        pinLeftLabel.text = [NSString stringWithFormat:@"%@%@ left", [Common currencyFloatRemake:data.pinLeftAmount],[Common currencyCodeToSymbol:data.pinCurrencyCode]];
        pinLeftLabel.adjustsFontSizeToFitWidth=YES;
        pinLeftLabel.minimumScaleFactor=0.5;

        //THIS PART

        UIView *circleView = (UIView *)[cell viewWithTag:104];
        [circleView addSubview:[Customview alloc]initWithOriginal:data.pinOriginalAmount andLeft:data.pinLeftAmount];  
    }

数组没有变，其他标签也没有变，只是 subview 不对

向下和向上滚动: https://drive.google.com/file/d/0BwtBKpSMH_eHWkxmeDNGQUJvdnM/view?usp=sharing

Answer 1

我认为问题出在这里

UIView *circleView = (UIView *)[cell viewWithTag:104];
[circleView addSubview:[Customview alloc]initWithOriginal:data.pinOriginalAmount andLeft:data.pinLeftAmount];  

当您重用单元格时，它将包含 2 个 circleView... 你应该删除之前的那个，或者重用 circleView 本身
