如何防止UISearchBar向上移动

Question

我把UISearchBar放在UIView下，如下图所示。问题是 - 在完成搜索或单击取消后，UISearchBar将转移到顶部，然后我收到错误消息：

2014-05-22 15:45:18.663 MyAPP[14402:60b] *** Assertion failure in -[UITableView layoutSublayersOfLayer:], /SourceCache/UIKit_Sim/UIKit-2935.137/UIView.m:8794

问题：

1）是否可以修复UISearchBar的位置？以及如何做到这一点？

2）如何解决错误？
