ios – UISearchController导致黑屏Swift 2.0

概述我在使用Swift 2.0的iOS 9中遇到了一个奇怪的问题.我在tableViewController中添加了UISearchController但它会导致一个奇怪的黑屏问题.当我按下搜索栏并写一些东西时,它显示我的过滤结果没有任何问题,但当我点击另一个标签栏按钮,如书签,然后当我点击tableViewController再次观看时,它显示黑屏像屏幕截图. 有我的tableViewControl 我在使用Swift 2.0的iOS 9中遇到了一个奇怪的问题.我在tableVIEwController中添加了UISearchController但它会导致一个奇怪的黑屏问题.当我按下搜索栏并写一些东西时,它显示我的过滤结果没有任何问题,但当我点击另一个标签栏按钮,如书签,然后当我点击tableVIEwController再次观看时,它显示黑屏像屏幕截图.

有我的tableVIEwController;

.name?.lowercaseString.rangeOfString(searchText) != nil})        self.filteredVeterinarIEs += self.veterinarIEs.filter({.town?.lowercaseString.rangeOfString(searchText) != nil})        tableVIEw.reloadData()    }}

这是来自iOS 9模拟器的黑屏图像,与真实设备相同.

当我点击searchbar并且它无法再次启动时,我认为它会消除我的tableVIEw.这是一个错误还是什么？

我怎么解决这个问题 ？

谢谢 ！

解决方法 朋友,在你的vIEwDIDLoad()中插入以下代码行：
