Question

有人遇到同样困扰的问题吗？我无法弄清楚UIView会向他发送发布消息。

非常感谢您的任何建议。

我的测试代码严格遵循Apple tableView / Search示例代码指南。初始TableView工作完美。触发过滤后的tableView以显示在UISearchController中 - ＆gt; searchResultsController，代码如下。

func updateSearchResultsForSearchController(searchController: UISearchController) {

...

        let tableController = self.searchController!.searchResultsController as! FilteredTableViewController
        tableController.datasource = self.tableData?.tableFilteredCellRecords
        tableController.navController = self.navigationController
        tableController.tableView.reloadData()
...
}

在过滤后的tableView中，单元格行显示OK，然后单击任意单元格以触发细节UIView显示，代码如下：

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    let record = self.tableData!.getFilteredTableRecord(indexPath.row)

    if(record != nil) {
        let detailViewController = DetailViewController()
        detailViewController.titleText = record?.title
        detailViewController.descText = record?.desc
        detailViewController.imgExist = record!.imgview

    self.navigationController?.pushViewController(detailViewController, animated: false)

    }
}

然后细节UIView显示效果很好，但点击“返回”后按钮返回TableView，App崩溃。

启用Zombie后，调试报告：

Answer 1

试试这个

   self.view = [[UIView alloc]initWithFrame:self.view.frame];

更改viewController ..

Answer 2

在stackoverflow中阅读了很多讨论后，最后得到一个有用的建议，这真的有效。 '不要同时推动两个viewControllers动画。在没有动画的情况下推送第一个，然后用动画推动第二个动画。 UINavigationController无法同时处理两个动画'

UINavigationController crash because of pushing and poping UIViewControllers

最后，只更改一行代码：self.navigationController？.pushViewController（），将动画设置为true。这个bug是修复的。我无法相信这是iOS错误或一些未知的知识。

iOS过滤后的tableview导航按UIView，然后UIView返回导致崩溃
