iOS 6.1与willTransitionToState的行为不同
我正在为我的UITableCell子类，以便将Minus图像和EditMode中的Delete图像移动到相反的方向。 它到目前为止工作得很好，但在iOS 6中，当我在tableView上使用reloadData时，负图像跳转到单元格的左侧而不是保持在右侧。 我不知道在iOS 6中发生了什么变化来触发这种行为。
我不知道是不是导致这个问题的原因，但是我已经记录了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：

如果在xib上启用了自动布局，则可能是问题的原因。 这个答案可能会提供一些洞察内容， 而不是在iOS 6 UITableViewCell原型单元中缩进
