Ios 无法删除UITableView中的行

我有两个数组，在删除行时需要从中删除数据，这两个数组似乎都已删除。但是，当我滑动以删除时，会出现以下错误：

[2078:568325]***在-[UITableView]中的断言失败 _endCellAnimationsWithContext:，/SourceCache/UIKit/UIKit-3318.16.21/UITableView.m:1582[2078:568325] ***由于未捕获异常“NSInternalInconsistencyException”而终止应用程序，原因：“无效更新：无效” 节0中的行数。表中包含的行数 更新2后的现有节数必须等于 更新2之前该节中包含的行，加号或减号 从插入的节0插入或删除的行数， 1删除并加上或减去移入或移出的行数 第0节搬进来了，第0节搬出去了。”

它似乎在deleteRowsAtIndexPaths上出错

在从数据模型中删除元素之前，请尝试移动调用以删除行。大概是这样的：

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {

    if editingStyle == UITableViewCellEditingStyle.Delete {
        audioPlayers[indexPath.row].stop()
        tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
        audioFiles.removeAtIndex(indexPath.row)
        audioPlayers.removeAtIndex(indexPath.row)
    }

}

我让它像

        override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
        if editingStyle == .Delete {
            managedObjectContext.deleteObject(fetchedResultsController.objectAtIndexPath(indexPath) as! NSManagedObject)
            do {
                try managedObjectContext.save()
            } catch {
                print("error managed object context in dictionary table")
            }
        } else if editingStyle == .Insert {

        }    
    }
  func controller(controller: NSFetchedResultsController, didChangeObject anObject: AnyObject, atIndexPath indexPath: NSIndexPath?, forChangeType type: NSFetchedResultsChangeType, newIndexPath: NSIndexPath?) {
        switch type {
        case NSFetchedResultsChangeType.Insert:
            tableView.insertRowsAtIndexPaths([newIndexPath!], withRowAnimation: .Fade)
        case NSFetchedResultsChangeType.Delete:
            tableView.deleteRowsAtIndexPaths([indexPath!], withRowAnimation: .Fade)
        case NSFetchedResultsChangeType.Move:
            tableView.deleteRowsAtIndexPaths([indexPath!], withRowAnimation: .Fade)
            tableView.insertRowsAtIndexPaths([newIndexPath!], withRowAnimation: .Fade)
        case NSFetchedResultsChangeType.Update:
            tableView.cellForRowAtIndexPath(indexPath!)
        }
    }

    func controller(controller: NSFetchedResultsController, didChangeSection sectionInfo: NSFetchedResultsSectionInfo, atIndex sectionIndex: Int, forChangeType type: NSFetchedResultsChangeType) {
        switch type {
        case NSFetchedResultsChangeType.Insert:
            tableView.insertSections(NSIndexSet(index: sectionIndex), withRowAnimation: .Fade)
        case NSFetchedResultsChangeType.Delete:
            tableView.deleteSections(NSIndexSet(index: sectionIndex), withRowAnimation: .Fade)
        case NSFetchedResultsChangeType.Move:
            tableView.deleteSections(NSIndexSet(index: sectionIndex), withRowAnimation: .Fade)
            tableView.insertSections(NSIndexSet(index: sectionIndex), withRowAnimation: .Fade)
        case NSFetchedResultsChangeType.Update:
            break
        }
    }

表中的行数返回什么值view@chrono删除数据后，需要重新加载tableView。最后，请尝试[tableView reloadData]返回enumeratedDocumentDirectory函数的计数，该函数返回strings@Akshay我把它扔进去了，但它还是扔了同样的错误。我把它放在removeAtIndex和tableView之间。deleteRows@chrono尝试将其放在删除和调试该部分中的代码之后，因为更新表视图和删除itemNegatory没有意义。谢谢你的建议。似乎只是没有更新我的文档模型中的行。您的意思是应用我的解决方案后，您看不到您的数据模型音频文件和音频播放器更新吗？

        override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
