问题描述
我正在将项目更新到iOS 8，并且正在使用我的一个UITableViewCell实现来解决这个问题。目前在模拟器上而不是设备，它被设置为iPhone 6。
I am updating a project to iOS 8 and am running into this issue with one of my UITableViewCell implementations. Currently on Simulator and not a device and it is set to "iPhone 6".
*** Assertion failure in -[UITableViewCell _setHostsLayoutEngine:], /SourceCache/UIKit_Sim/UIKit-3318/NSLayoutConstraint_UIKitAdditions.m:2754
2014-09-15 10:43:52.890 BasketballStatTracker[10662:304085] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Must translate autoresizing mask into constraints to have _setHostsLayoutEngine:YES.'
奇怪的是我在所有其他UITableViews中使用这个自定义UITableViewCell子类并且它正在工作没有任何断言。
The odd part is that I am using this Custom UITableViewCell subclass in all my other UITableViews and it is working well without any asserts.
这是cellForRowAtIndexPath：实现。
Here is the cellForRowAtIndexPath: implementation.
MyTableCell *cell =(MyTableCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell =[[MyTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
这是堆栈跟踪

任何想法？
推荐答案
我找到了一个放置在视图层次结构中的错误UITableViewCell陷入困境的.xib。删除它修复了问题。
I located an errant UITableViewCell that was placed within the view hierarchy of the troubled .xib. Removing it fixed the problem.
