iOS8 Swift：deleteRowsAtIndexPaths崩溃

iOS8 Swift：deleteRowsAtIndexPaths崩溃

使用Xpre Core Data Master-
Detail模板项目很容易重现崩溃。通常，当您使用时

NSFetchedResultsController

，您应该真正使用

NSFetchedResultsControllerDelegate

（您已声明但不使用它）。

删除

tableView:commitEditingStyle:forRowAtIndexPath:

方法中的这些行：

tableViewMain.beginUpdates()tableViewMain!.deleteRowsAtIndexPaths([indexPath!], withRowAnimation: UITableViewRowAnimation.Fade)tableViewMain.endUpdates()

并将这些行添加到您的viewController类中：

func controllerWillChangeContent(controller: NSFetchedResultsController) {    tableViewMain.beginUpdates()}func controller(controller: NSFetchedResultsController!, didChangeSection sectionInfo: NSFetchedResultsSectionInfo!, atIndex sectionIndex: Int, forChangeType type: NSFetchedResultsChangeType) {    switch type {    case .Insert:        tableViewMain.insertSections(NSIndexSet(index: sectionIndex), withRowAnimation: .Fade)    case .Delete:        tableViewMain.deleteSections(NSIndexSet(index: sectionIndex), withRowAnimation: .Fade)    default:        return    }}func controller(controller: NSFetchedResultsController!, didChangeObject anObject: AnyObject!, atIndexPath indexPath: NSIndexPath!, forChangeType type: NSFetchedResultsChangeType, newIndexPath: NSIndexPath!) {    switch type {    case .Insert:        tableViewMain.insertRowsAtIndexPaths([newIndexPath], withRowAnimation: .Fade)    case .Delete:        tableViewMain.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)    case .Update:        return        //Should also manage this case!!!        //self.configureCell(tableView.cellForRowAtIndexPath(indexPath), atIndexPath: indexPath)    case .Move:        tableViewMain.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)        tableViewMain.insertRowsAtIndexPaths([newIndexPath], withRowAnimation: .Fade)    default:        return    }}func controllerDidChangeContent(controller: NSFetchedResultsController!) {    tableViewMain.endUpdates()}

这应该可以解决您的问题。
