当滚动uitableview时，UiSegementedController的段自动在UITableViewCell中选择

Question

我已将UISegmentedController添加到TableViewCell中的CellForRowAtIndexPath。
以下是代码。

[cell.segStatus addTarget:self action:@selector(selectedSegmentControl:) forControlEvents: UIControlEventValueChanged];
[cell.segStatus setSegmentedControlStyle:UISegmentedControlStyleBar];
cell.segStatus.tag = indexPath.row;

我将UITableViewCell类用于自定义类。

我选择片段，当我滚动桌面视图时，其他单元格的分段控制器也会自动选择 为什么？我该怎么解决这个问题？
