删除搜索栏表格视图中的单元格会导致执行两次删除(Deleting a cell in search bar table view causes delete to be executed twice)

问题 我有一个由核心数据与NSFetchedResultsController实例备份的表视图。 此表有一个显示过滤数据的搜索栏。 搜索栏有一个单独的NSFetchedResultsController (现在是 FRC)实例。 到目前为止一切顺利,数据在表格视图中按预期获取和显示,并且在搜索栏的表格视图中也正确显示(搜索数据时)。 我的问题是,如果我尝试删除搜索栏表格视图中的单元格,则会出现coredata异常: 错误:严重的应用程序错误。 在调用 -controllerDidChangeContent: 期间,从 NSFetchedResultsController 的委托中捕获了异常。 尝试从第 0 节中删除第 0 行,该第 0 行在更新前仅包含 0 行 userInfo (null) 进一步检查表明,FRC 的controllerWillChangeContent方法在一个单元格删除时被调用两次! 这会导致deleteRowsAtIndexPaths为同一个单元deleteRowsAtIndexPaths用两次(因此 coredata 异常)。 再玩一玩,我发现这个问题是在搜索后第一次显示搜索栏的表格视图时发生的。 (即使我回去删除常规表格视图中的单元格也会出现问题) 我已经确保deleteRowsAtIndexPaths方法在代码中只调用一次(在 FRC

Laravel 搜索栏(Laravel search bar)

问题 我正在尝试为一个项目构建一个搜索栏,“最有效”的那个是来自 w3 的那个我不是要在你可以按 Enter 的地方制作一个搜索栏,而是一个可以过滤单词的搜索栏,而无需连接到我的数据库。 这是我的代码: <div class="dropdown-menu"> <input type="text" class="form-control" id="myInput" onkeyup="myFunction()"placeholder="search.." title="namesearch"> <div class="dropdown-divider"></div> @foreach($users as $user) <ul id="myUL"> <li><a href="#">{{ $user->username }}</a></li> </ul> @endforeach </div> </div> 而对于我的 javascript(它只过滤最上面的一个(不知道为什么)) var input, filter, ul, li, a, i, txtValue; input = document.getElementById("myInput"); filter = input.value.toUpperCase(); ul = document.getElementById("myUL"

speech recognition does not return good the value on time ionic 5

I have a problem with this ionic plugin, I do everything right, but when you bring me the data, it does so after a subsequent action, such as pressing the button again or simply pressing some other element.

Deleting a cell in search bar table view causes delete to be executed twice

I have a table view backed up by core data with NSFetchedResultsController instance. This table has a search bar that displays filtered data. The search bar has a separate NSFetchedResultsController (FRC from now) instance. So far so good, the data is fetched and shown as expected in the table view and also shown correctly in the search bar's table view (when searching for data). My problem is that if I try to delete a cell in the search bar's table view then I get a coredata exception : error: Serious application error. An exception was caught from the delegate of NSFetchedResultsController

快速从表视图问题中搜索动态数据问题(Searching dynamic data issue from table view issue in swift)

在我的 TableView 中实现 SearchBar 并使用 NSFetchedResultsController 和适当的谓词使搜索工作(Implementing a SearchBar inside my TableView and using NSFetchedResultsController and the appropriate predicate to get searches working)

问题 我有一个简单的 TableViewController,它有一个添加按钮,它转到一个 ModalViewController; 用户将文本添加到文本字段中,按保存并关闭,条目将添加到核心数据中的实体和属性并显示在 TableViewController 中。 它运作良好。 我首先从另一个按钮开始,它在表视图中拉出一个 UISearchBar,我可以搜索结果并将其拉回来; 那行得通。 然后我在 TableViewController 的底部添加了一个新选项卡,并设法在那里获取搜索栏和表格。 现在,我希望 SearchBar 位于 Single Table View 的顶部,并且我希望用户能够键入并动态搜索 TableView。 我的 fetchRequest 目前对于 TableView 看起来像这样(没有搜索栏): NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Transaction" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]

Implementing a SearchBar inside my TableView and using NSFetchedResultsController and the appropriate predicate to get searches working

I have a simple TableViewController which has an add button which goes over to a ModalViewController; the user adds in text into a text field, presses save and that dismisses and the entry is added to the Entities and Attributes in Core Data and displayed in the TableViewController. It works well. I firstly started off with another button that pulled up a UISearchBar in a Table View and I could search for results and pull that back; that worked. I then added a new tab to the bottom of the TableViewController and managed to get the search bar and table in there. Now, I want the SearchBar at the

Laravel search bar

I'm trying to build a search bar for a project, the one that worked "the most" was the one from w3 I'm not trying to make one whhere youcan press enter, but just one that filters on the words, without connecting to my database. Here is my code: <div class="dropdown-menu"> <input type="text" class="form-control" id="myInput" onkeyup="myFunction()"placeholder="search.." title="namesearch"> <div class="dropdown-divider"></div> @foreach($users as $user) <ul id="myUL"> <li><a href="#">{{ $user->username }}</a></li> </ul> @endforeach </div> </div> And for my javascript (which only filters the top
