表格视图在真实设备上不刷新

【中文标题】表格视图在真实设备上不刷新【英文标题】：Table view is not refreshing on real device 【发布时间】：2015-05-06 07:07:09 【问题描述】：我的表格视图有问题。
当我选择行时，我的单元格高度正在改变并显示一些信息。如果我第二次选择，它正在关闭。
在模拟器上就像一个魅力，但在真实设备上，第一部分工作正常，但当我想关闭它时，他正在执行代码但可能没有刷新 tableView，因为我的信息保持显示。
真实设备的另一个问题：我的视图没有出现。

我不知道这是否是问题，但是当我在真实设备中第一次按下后，行正在改变颜色。为什么？有什么想法吗？
【问题讨论】：
我猜你滚动时会发生这种情况？ 没有。我的行只是没有关闭.. :( 不要开启滚动功能试试看 如果我禁用滚动功能，我看不到关于描述和carac的信息。 【参考方案1】：如果在模拟器中一切正常但在设备中运行良好，则检查“dequeueReusableCellWithIdentifier”/“CellID”值，因为模拟器不区分大小写，但设备区分大小写。
可能是找不到你的手机ID所以它发生了，我不确定但只检查一次。
