我将我UITableCell的子类化，以便将 EditMode 中的减号图像和删除图像移动到相反的方向。到目前为止效果很好，但是在 iOS 6 中，当我在 tableView 上使用 reloadData 时，减号图像会跳到单元格的左侧，而不是停留在右侧。我不知道 iOS 6 中发生了什么变化来触发这种行为。
我不知道这是否是导致问题的原因，但我已经记录了 iOS 5 和 iOS 6 中的所有来源，唯一的区别是：
iOS 5.0： 日志 5 - 状态 1 和 3：560.000000、 0.000000 、 41.000000 、 40.000000
iOS 6.1： 日志 5 - 状态 1 和 3：808.000000、 0.000000 、 41.000000 、 40.000000
这是代码：
