核心数据swift xcode 6问题 [英] core data swift xcode 6 question

问题描述

我正在尝试在表格中显示项目但是应用程序保存在核心数据中而没有显示，任何人都可以知道这里的问题，因为它没有显示应用程序有任何问题。

I'm trying to display an items in the table but the app is saved in the core data without displayed can anyone know what the problem here because it's doesn't show that the app have any problem.

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
    if segue.identifier == "edit" {
        let cell = sender as! UITableViewCell
        let indexPath = tableView.indexPathForCell(cell)
        let itemController: ViewController = segue.destinationViewController as! ViewController
        let nItem: ItemList = frc.objectAtIndexPath(indexPath!) as! ItemList
        itemController.nItem = nItem

这里显示项目的代码新的视图控制器。
