iOS 6.1的行为与willTransitionToState不同 [英] iOS 6.1 is acting differently with willTransitionToState
本文介绍了iOS 6.1的行为与willTransitionToState不同的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我将子类化我的 UITableCell ，以移动减号图像和删除图像在EditMode到相反的方向。它的工作伟大到目前为止，但在iOS 6当我使用reloadData在我的tableView减图像跳转到单元格的左侧，而不是停留在右边。我不知道什么改变在iOS 6中触发的行为。
我不知道这是什么原因导致的问题，但我已经记录所有的起源在iOS 5和iOS 6，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

解决方案
如果在xib上启用了自动布局，可能是问题的原因。此答案可能提供一些见解 contentView不缩进iOS 6 UITableViewCell原型单元
I'm subclassing my UITableCell in order move the Minus image and the Delete image in EditMode to the oposite direction. It worked great so far but in iOS 6 when I use reloadData on my tableView the minus image jumps to the left side of the cell instead of staying on the right. I have no idea what changed in iOS 6 to trigger that behavior.
I don't know if that's what is causing the issue but I've logged all the origins in iOS 5 and iOS 6 and the only difference was:
iOS 5.0: Log 5 - State 1 And 3: 560.000000 , 0.000000 , 41.000000 , 40.000000
iOS 6.1: Log 5 - State 1 And 3: 808.000000 , 0.000000 , 41.000000 , 40.000000
