Question

我正在使用UITableView。

 CategoryCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierLink];

这是我收到错误的行。它在IOS 7中工作。但是当我在IOS 8中运行应用程序时，我收到了错误

** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Must translate autoresizing mask into constraints to have _setHostsLayoutEngine:YES.

在此处查看答案：why do i get "Must translate autoresizing mask into constraints to have _setHostsLayoutEngine:YES" in xcode 6 beta

这暂时为我解决了。

Answer 2

我已经看到这种情况发生了约束。尝试运行删除了约束的代码，然后逐个重新添加。
