iOS过滤的tableview导航推UIView，然后UIView回导致崩溃

问题描述：

有人遇到了同样的麻烦问题吗？我无法弄清楚UIView会向谁发送发布消息。iOS过滤的tableview导航推UIView，然后UIView回导致崩溃

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。并且过滤的tableView被触发以显示在UISearchController - > searchResultsController中，代码如下所示。

func updateSearchResultsForSearchController(searchController: UISearchController) { 

... 

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

在过滤的tableView，单元行显示行，然后点击任何细胞触发细节的UIView显示，代码是象下面这样：

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，详细的UIView显示良好，但是当点击'返回“按钮返回TableView，应用程序崩溃。

启用后僵尸，调试报告：

答

试试这个

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

改变的viewController时..

答

在计算器看了很多讨论后，最终得到一个有用的建议，这真的有用。 '不要同时推动两个viewController动画。推动第一个没有动画，并推动第二个与动画。的UINavigationController不能在同一时间”

UINavigationController crash because of pushing and poping UIViewControllers

最后，只改变一行代码处理两个动画：self.navigationController .pushViewController（），设置动画为真。这个bug已修复。我无法相信这是iOS的错误，或者一些未知的知识。
