我不知道我做错了什么,我把它设置为获取数据了使用此代码
var appDel:AppDelegate = (UIApplication.sharedApplication().delegate as AppDelegate)
var context:NSManagedObjectContext = appDel.managedObjectContext!
var request = NSFetchRequest(entityName: "Subject")
request.returnsObjectsAsFaults = false;
这完美的作品称为“主体”的实体,如果有只有一个实体。 先进的感谢
删除设备上的应用程序,然后重建您的项目。它应该解决你的问题。 – 2014-10-04 12:08:47
